Dear Wiki user,

The "API" page has been changed by JonHermes.

--------------------------------------------------

  
  Remove data from the row specified by `key` at the granularity specified by `column_path`, and the given `timestamp`.  Note that all the values in `column_path` besides `column_path.column_family` are truly optional: you can remove the entire row by just specifying the !ColumnFamily, or you can remove a !SuperColumn or a single Column by specifying those levels too. Note that the `timestamp` is needed, so that if the commands are replayed in a different order on different nodes, the same result is produced.
  
+ === describe_cluster_name ===
+ ''Requires Cassandra 0.6''
+ 
+  . `string describe_cluster_name()`
+ 
+ Gets the name of the cluster.
+ 
+ === describe_version ===
+ ''Requires Cassandra 0.6''
+ 
+  . `string describe_version()`
+ 
+ Gets the Thrift API version.
+ 
+ === describe_ring ===
+ ''Requires Cassandra 0.6''
+ 
+  . `list<TokenRange> describe_ring(string keyspace)`
+ 
+ Gets the token ring; a map of ranges to host addresses. Represented as a set of `TokenRange` instead of a map from range to list of endpoints, because you can't use Thrift structs as map keys: https://issues.apache.org/jira/browse/THRIFT-162 for the same reason, we can't return a set here, even though order is neither important nor predictable.

+ === describe_keyspace ===
+ ''Requires Cassandra 0.7''
+ 
+  . `KsDef describe_keyspace(string keyspace)`
+ 
+ Gets information about the specified keyspace.

  === describe_keyspaces ===
- ''Requires Cassandra 0.6''
+ ''Requires Cassandra 0.7''
  
-  . `set<string> describe_keyspaces()`
+  . `list<KsDef> describe_keyspaces()`
  
+ Gets a list of all the keyspaces configured for the cluster. (Equivalent to calling describe_keyspace(k) for k in keyspaces.)
- Gets a list of all the keyspaces configured for the cluster.
