All CQL statements are executed directly against the Cassandra server CQL statementsThis interpreter is compatible with any CQL statement supported by Cassandra. Ex:INSERT INTO users(login,name) VALUES(&#39;jdoe&#39;,&#39;John DOE&#39;);SELECT * FROM users WHERE login=&#39;jdoe&#39;;Each statement should be separated by a semi-colon ( ; ) except the special commands below:@prepare@bind@remove_prepare@consistency@serialConsistency@timestamp@retryPolicy@fetchSize@requestTimeOutMulti-line statements as well as multiple statements on the same line are also supported as long as they are separated by a semi-colon.

Single line comments start with the hash sign (#) or double slashes (//). Multi-line comments are enclosed between /** and **/. Ex:#Single line comment style 1INSERT INTO users(login,name) VALUES(&#39;jdoe&#39;,&#39;John DOE&#39;);//Single line comment style 2/** Multi line comments **/Insert into users(login,name) vAlues(&#39;hsue&#39;,&#39;Helen SUE&#39;);Syntax ValidationThe interpreters is shipped with a built-in syntax validator. This validator only checks for basic syntax errors.All CQL-related syntax validation is delegated directl
y to CassandraMost of the time, syntax errors are due to missing semi-colons between statements or typo errors.Schema commandsTo make schema discovery easier and more interactive, the following commands are supported: Command Description DESCRIBE CLUSTER; Show the current cluster name and its partitioner DESCRIBE KEYSPACES; List all existing keyspaces in the cluster and their configuration (replication factor, durable write ...) DESCRIBE TABLES; List all existing keyspaces in the cluster and for each, all the tables name DESCRIBE TYPES; List all existing keyspaces in the cluster and for each, all the user-defined types name DESCRIBE FUNCTIONS; List all existing keyspaces in the cluster and for each, all the functions name DESCRIBE AGGREGATES; List all existing keyspaces in the cluster and for each, all the aggregates name DESCRIBE MATERIALIZED VIEWS; List all existing keyspa
ces in the cluster and for each, all the materialized views name DESCRIBE KEYSPACE &lt;keyspacename&gt;; Describe the given keyspace configuration and all its table details (name, columns, ...) DESCRIBE TABLE (&lt;keyspacename&gt;).&lt;tablename&gt;; Describe the given table. If the keyspace is not provided, the current logged in keyspace is used. If there is no logged in keyspace, the default system keyspace is used. If no table is found, an error message is raised DESCRIBE TYPE (&lt;keyspacename&gt;).&lt;typename&gt;; Describe the given type(UDT). If the keyspace is not provided, the current logged in keyspace is used. If there is no logged in keyspace, the default system keyspace is used. If no type is found, an error message is raised DESCRIBE FUNCTION (&lt;keyspacename&gt;).&lt;functionname&gt;; Describe the given
function. If the keyspace is not provided, the current logged in keyspace is used. If there is no logged in keyspace, the default system keyspace is used. If no function is found, an error message is raised DESCRIBE AGGREGATE (&lt;keyspacename&gt;).&lt;aggregatename&gt;; Describe the given aggregate. If the keyspace is not provided, the current logged in keyspace is used. If there is no logged in keyspace, the default system keyspace is used. If no aggregate is found, an error message is raised DESCRIBE MATERIALIZED VIEW (&lt;keyspacename&gt;).&lt;view_name&gt;; Describe the given view. If the keyspace is not provided, the current logged in keyspace is used. If there is no logged in keyspace, the default system keyspace is used. If no view is found, an error message is raised The schema objects (cluster, keyspace, table, type, function and aggregate) are disp
layed in a tabular format.There is a drop-down menu on the top left corner to expand objects details. On the top right menu is shown the Icon legend. Runtime ParametersSometimes you want to be able to pass runtime query parameters to your statements.Those parameters are not part of the CQL specs and are specific to the interpreter.Below is the list of all parameters: Parameter Syntax Description Consistency Level @consistency=value Apply the given consistency level to all queries in the paragraph Serial Consistency Level @serialConsistency=value Apply the given serial consistency level to all queries in the paragraph Timestamp @timestamp=long value Apply the given timestamp to all queries in the paragraph. Please note that timestamp value passed directly in CQL statement will override this value Retry Policy @retryPolicy=value Apply the given retry policy to all queries in t
he paragraph Fetch Size @fetchSize=integer value Apply the given fetch size to all queries in the paragraph Request Time Out @requestTimeOut=integer value Apply the given request timeout in millisecs to all queries in the paragraph Some parameters only accept restricted values: Parameter Possible Values Consistency Level ALL, ANY, ONE, TWO, THREE, QUORUM, LOCALONE, LOCALQUORUM, EACHQUORUM Serial Consistency Level SERIAL, LOCALSERIAL Timestamp Any long value Retry Policy DEFAULT, DOWNGRADINGCONSISTENCY, FALLTHROUGH, LOGGINGDEFAULT, LOGGINGDOWNGRADING, LOGGINGFALLTHROUGH Fetch Size Any integer value Please note that you should not add semi-colon ( ; ) at the end of each parameter statementSome examples:CREATE TABLE IF NOT EXISTS spark_demo.ts( key int PRIMARY KEY, value text);TRUNCATE spark_demo.ts;// Timestamp in the past@timestamp=10// Force timestamp dir
ectly in the first insertINSERT INTO spark_demo.ts(key,value) VALUES(1,&#39;first insert&#39;) USING TIMESTAMP 100;// Select some data to make the clock turnSELECT * FROM spark_demo.albums LIMIT 100;// Now insert using the timestamp parameter set at the beginning(10)INSERT INTO spark_demo.ts(key,value) VALUES(1,&#39;second insert&#39;);// Check for the result. You should see &#39;first insert&#39;SELECT value FROM spark_demo.ts WHERE key=1;Some remarks about query parameters:many query parameters can be set in the same paragraphif the same query parameter is set many time with different values, the interpreter only take into account the first valueeach query parameter applies to all CQL statements in the same paragraph, unless you override the option using plain CQL text (like forcing timestamp with the USING clause)the order of each query parameter with regard to CQL statement does not matterSupport for Prepared StatementsFor performance reason, it is better
to prepare statements before-hand and reuse them later by providing bound values.This interpreter provides 3 commands to handle prepared and bound statements:@prepare@bind@remove_preparedExample:@prepare[statement-name]=...@bind[statement-name]=âtextâ, 1223, â2015-07-30 12:00:01â, null, true, [âlist_item1â, âlist_item2â]@bind[statement-name-with-no-bound-value]@remove_prepare[statement-name]@prepareYou can use the syntax &quot;@prepare[statement-name]=SELECT...&quot; to create a prepared statement.The statement-name is mandatory because the interpreter prepares the given statement with the Java driver andsaves the generated prepared statement in an internal hash map, using the provided statement-name as search key.Please note that this internal prepared statement map is shared with all notebooks and all paragraphs becausethere is only one instance of the interpreter for CassandraIf the interpreter encounters many @prepare for the same
statement-name (key), only the first statement will be taken into account.Example:@prepare[select]=SELECT * FROM spark_demo.albums LIMIT ?@prepare[select]=SELECT * FROM spark_demo.artists LIMIT ?For the above example, the prepared statement is SELECT * FROM spark_demo.albums LIMIT ?.SELECT * FROM spark_demo.artists LIMIT ? is ignored because an entry already exists in the prepared statements map with the key select.In the context of Zeppelin, a notebook can be scheduled to be executed at regular interval,thus it is necessary to avoid re-preparing many time the same statement (considered an anti-pattern).@bindOnce the statement is prepared (possibly in a separated notebook/paragraph). You can bind values to it:@bind[select_first]=10Bound values are not mandatory for the @bind statement. However if you provide bound values, they need to comply to some syntax:String values should be enclosed between simple quotes (&#39;)Date values should be enclosed between simple quotes (&#3
9;) and respect the formats (full list is in the documentation):yyyy-MM-dd HH:MM:ssyyyy-MM-dd HH:MM:ss.SSSnull is parsed as-isboolean (true|false) are parsed as-iscollection values must follow the standard CQL syntax:list: [&#39;listitem1&#39;, &#39;listitem2&#39;, ...]set: {&#39;setitem1&#39;, &#39;setitem2&#39;, â¦}map: {&#39;key1&#39;: &#39;val1&#39;, &#39;key2&#39;: &#39;val2&#39;, â¦}tuple values should be enclosed between parenthesis (see Tuple CQL syntax): (&#39;text&#39;, 123, true)udt values should be enclosed between brackets (see UDT CQL syntax): {streename: &#39;Beverly Hills&#39;, number: 104, zipcode: 90020, state: &#39;California&#39;, â¦}It is possible to use the @bind statement inside a batch:BEGIN BATCH @bind[insert_user]=&#39;jdoe&#39;,&#39;John DOE&#39; UPDATE users SET age = 27 WHERE login=&#39;hsue&#39;;APPLY BATCH;@remove_prepareTo av
oid for a prepared statement to stay forever in the prepared statement map, you can use the@remove_prepare[statement-name] syntax to remove it.Removing a non-existing prepared statement yields no error.Using Dynamic FormsInstead of hard-coding your CQL queries, it is possible to use [Zeppelin dynamic form] syntax to inject simple value or multiple choices forms.The legacy mustache syntax ( {{ }} ) to bind input text and select form is still supported but is deprecated and will be removed in future releases.LegacyThe syntax for simple parameter is: {{input_Label=default value}}. The default value is mandatory because the first time the paragraph is executed,we launch the CQL query before rendering the form so at least one value should be provided.The syntax for multiple choices parameter is: {{input_Label=value1 | value2 | ⦠| valueN }}. By default the first choice is used for CQL querythe first time the paragraph is executed.Example:#Secondary index on performer styleSELECT nam
e, country, performerFROM spark_demo.performersWHERE name=&#39;${performer=Sheryl Crow|Doof|Fanfarlo|Los Paranoia}&#39;AND styles CONTAINS &#39;${style=Rock}&#39;;In the above example, the first CQL query will be executed for performer=&#39;Sheryl Crow&#39; AND style=&#39;Rock&#39;.For subsequent queries, you can change the value directly using the form.Please note that we enclosed the ${ } block between simple quotes ( &#39; ) because Cassandra expects a String here.We could have also use the ${style=&#39;Rock&#39;} syntax but this time, the value displayed on the form is &#39;Rock&#39; and not Rock.It is also possible to use dynamic forms for prepared statements:@bind[select]==&#39;${performer=Sheryl Crow|Doof|Fanfarlo|Los Paranoia}&#39;, &#39;${style=Rock}&#39;Shared statesIt is possible to execute many paragraphs in parallel. However, at the back-end side, we&#39;re still using synchronous queries.Asynchrono
us execution is only possible when it is possible to return a Future value in the InterpreterResult.It may be an interesting proposal for the Zeppelin project.Recently, Zeppelin allows you to choose the level of isolation for your interpreters (see [Interpreter Binding Mode] ).Long story short, you have 3 available bindings:shared : same JVM and same Interpreter instance for all notesscoped : same JVM but different Interpreter instances, one for each noteisolated: different JVM running a single Interpreter instance, one JVM for each noteUsing the shared binding, the same com.datastax.driver.core.Session object is used for all notes and paragraphs.Consequently, if you use the USE keyspace_name; statement to log into a keyspace, it will change the keyspace forall current users of the Cassandra interpreter because we only create 1 com.datastax.driver.core.Session objectper instance of Cassandra interpreter.The same remark does apply to the prepared statement hash map, it is shared by a
ll users using the same instance of Cassandra interpreter.When using scoped binding, in the same JVM Zeppelin will create multiple instances of the Cassandra interpreter, thus multiple com.datastax.driver.core.Session objects. Beware of resource and memory usage using this binding ! The isolated mode is the most extreme and will create as many JVM/com.datastax.driver.core.Session object as there are distinct notes.Interpreter ConfigurationTo configure the Cassandra interpreter, go to the Interpreter menu and scroll down to change the parameters.The Cassandra interpreter is using the official Cassandra Java Driver and most of the parameters are usedto configure the Java driverBelow are the configuration parameters and their default values.

he paragraph Fetch Size @fetchSize=integer value Apply the given fetch size to all queries in the paragraph Request Time Out @requestTimeOut=integer value Apply the given request timeout in millisecs to all queries in the paragraph Some parameters only accept restricted values: Parameter Possible Values Consistency Level ALL, ANY, ONE, TWO, THREE, QUORUM, LOCALONE, LOCALQUORUM, EACHQUORUM Serial Consistency Level SERIAL, LOCALSERIAL Timestamp Any long value Retry Policy DEFAULT, DOWNGRADINGCONSISTENCY, FALLTHROUGH, LOGGINGDEFAULT, LOGGINGDOWNGRADING, LOGGINGFALLTHROUGH Fetch Size Any integer value Please note that you should not add semi-colon ( ; ) at the end of each parameter statementSome examples:CREATE TABLE IF NOT EXISTS spark_demo.ts( key int PRIMARY KEY, value text);TRUNCATE spark_demo.ts;// Timestamp in the past@timestamp=10// Force timestamp dir
ectly in the first insertINSERT INTO spark_demo.ts(key,value) VALUES(1,&#39;first insert&#39;) USING TIMESTAMP 100;// Select some data to make the clock turnSELECT * FROM spark_demo.albums LIMIT 100;// Now insert using the timestamp parameter set at the beginning(10)INSERT INTO spark_demo.ts(key,value) VALUES(1,&#39;second insert&#39;);// Check for the result. You should see &#39;first insert&#39;SELECT value FROM spark_demo.ts WHERE key=1;Some remarks about query parameters:many query parameters can be set in the same paragraphif the same query parameter is set many time with different values, the interpreter only take into account the first valueeach query parameter applies to all CQL statements in the same paragraph, unless you override the option using plain CQL text (like forcing timestamp with the USING clause)the order of each query parameter with regard to CQL statement does not matterSupport for Prepared StatementsFor performance reason, it is better
to prepare statements before-hand and reuse them later by providing bound values.This interpreter provides 3 commands to handle prepared and bound statements:@prepare@bind@remove_preparedExample:@prepare[statement-name]=...@bind[statement-name]=âtextâ, 1223, â2015-07-30 12:00:01â, null, true, [âlist_item1â, âlist_item2â]@bind[statement-name-with-no-bound-value]@remove_prepare[statement-name]@prepareYou can use the syntax &quot;@prepare[statement-name]=SELECT...&quot; to create a prepared statement.The statement-name is mandatory because the interpreter prepares the given statement with the Java driver andsaves the generated prepared statement in an internal hash map, using the provided statement-name as search key.Please note that this internal prepared statement map is shared with all notebooks and all paragraphs becausethere is only one instance of the interpreter for CassandraIf the interpreter encounters many @prepare for the same
statement-name (key), only the first statement will be taken into account.Example:@prepare[select]=SELECT * FROM spark_demo.albums LIMIT ?@prepare[select]=SELECT * FROM spark_demo.artists LIMIT ?For the above example, the prepared statement is SELECT * FROM spark_demo.albums LIMIT ?.SELECT * FROM spark_demo.artists LIMIT ? is ignored because an entry already exists in the prepared statements map with the key select.In the context of Zeppelin, a notebook can be scheduled to be executed at regular interval,thus it is necessary to avoid re-preparing many time the same statement (considered an anti-pattern).@bindOnce the statement is prepared (possibly in a separated notebook/paragraph). You can bind values to it:@bind[select_first]=10Bound values are not mandatory for the @bind statement. However if you provide bound values, they need to comply to some syntax:String values should be enclosed between simple quotes (&#39;)Date values should be enclosed between simple quotes (&#3
9;) and respect the formats (full list is in the documentation):yyyy-MM-dd HH:MM:ssyyyy-MM-dd HH:MM:ss.SSSnull is parsed as-isboolean (true|false) are parsed as-iscollection values must follow the standard CQL syntax:list: [&#39;listitem1&#39;, &#39;listitem2&#39;, ...]set: {&#39;setitem1&#39;, &#39;setitem2&#39;, â¦}map: {&#39;key1&#39;: &#39;val1&#39;, &#39;key2&#39;: &#39;val2&#39;, â¦}tuple values should be enclosed between parenthesis (see Tuple CQL syntax): (&#39;text&#39;, 123, true)udt values should be enclosed between brackets (see UDT CQL syntax): {streename: &#39;Beverly Hills&#39;, number: 104, zipcode: 90020, state: &#39;California&#39;, â¦}It is possible to use the @bind statement inside a batch:BEGIN BATCH @bind[insert_user]=&#39;jdoe&#39;,&#39;John DOE&#39; UPDATE users SET age = 27 WHERE login=&#39;hsue&#39;;APPLY BATCH;@remove_prepareTo av
oid for a prepared statement to stay forever in the prepared statement map, you can use the@remove_prepare[statement-name] syntax to remove it.Removing a non-existing prepared statement yields no error.Using Dynamic FormsInstead of hard-coding your CQL queries, it is possible to use [Zeppelin dynamic form] syntax to inject simple value or multiple choices forms.The legacy mustache syntax ( {{ }} ) to bind input text and select form is still supported but is deprecated and will be removed in future releases.LegacyThe syntax for simple parameter is: {{input_Label=default value}}. The default value is mandatory because the first time the paragraph is executed,we launch the CQL query before rendering the form so at least one value should be provided.The syntax for multiple choices parameter is: {{input_Label=value1 | value2 | ⦠| valueN }}. By default the first choice is used for CQL querythe first time the paragraph is executed.Example:#Secondary index on performer styleSELECT nam
e, country, performerFROM spark_demo.performersWHERE name=&#39;${performer=Sheryl Crow|Doof|Fanfarlo|Los Paranoia}&#39;AND styles CONTAINS &#39;${style=Rock}&#39;;In the above example, the first CQL query will be executed for performer=&#39;Sheryl Crow&#39; AND style=&#39;Rock&#39;.For subsequent queries, you can change the value directly using the form.Please note that we enclosed the ${ } block between simple quotes ( &#39; ) because Cassandra expects a String here.We could have also use the ${style=&#39;Rock&#39;} syntax but this time, the value displayed on the form is &#39;Rock&#39; and not Rock.It is also possible to use dynamic forms for prepared statements:@bind[select]==&#39;${performer=Sheryl Crow|Doof|Fanfarlo|Los Paranoia}&#39;, &#39;${style=Rock}&#39;Shared statesIt is possible to execute many paragraphs in parallel. However, at the back-end side, we&#39;re still using synchronous queries.Asynchrono
us execution is only possible when it is possible to return a Future value in the InterpreterResult.It may be an interesting proposal for the Zeppelin project.Recently, Zeppelin allows you to choose the level of isolation for your interpreters (see [Interpreter Binding Mode] ).Long story short, you have 3 available bindings:shared : same JVM and same Interpreter instance for all notesscoped : same JVM but different Interpreter instances, one for each noteisolated: different JVM running a single Interpreter instance, one JVM for each noteUsing the shared binding, the same com.datastax.driver.core.Session object is used for all notes and paragraphs.Consequently, if you use the USE keyspace_name; statement to log into a keyspace, it will change the keyspace forall current users of the Cassandra interpreter because we only create 1 com.datastax.driver.core.Session objectper instance of Cassandra interpreter.The same remark does apply to the prepared statement hash map, it is shared by a
ll users using the same instance of Cassandra interpreter.When using scoped binding, in the same JVM Zeppelin will create multiple instances of the Cassandra interpreter, thus multiple com.datastax.driver.core.Session objects. Beware of resource and memory usage using this binding ! The isolated mode is the most extreme and will create as many JVM/com.datastax.driver.core.Session object as there are distinct notes.Interpreter ConfigurationTo configure the Cassandra interpreter, go to the Interpreter menu and scroll down to change the parameters.The Cassandra interpreter is using the official Cassandra Java Driver and most of the parameters are usedto configure the Java driverBelow are the configuration parameters and their default values.
