-The section ["Plugin Configuration Basics"]({{site.baseurl}}/docs/plugin-configuration-basics) covers attributes that you configure for use with a CSV, TSV, PSV (comma-, tab-, pipe-separated) values text file. This section presents examples of how to use those attributes and [tips for performant querying]({{site.baseurl}}/docs/text-files-csv-tsv-psv/#tips-for-performant-querying) of these text files.
-## Managing Headers in Text Files
-In the storage plugin configuration, you set attributes on the text reader format configuration. This section presents examples of using the following attributes defined in ["List of Attributes and Definitions"]({{site.baseurl}}/docs/plugin-configuration-basics/#list-of-attributes-and-definitions):
+Best practices for reading text files are:
+
+* Select data from particular columns
+* CAST data
+* Use a distributed file system
+
+### Select Data from Particular Columns
+
+Converting text files to another format, such as Parquet, using the CTAS command and a SELECT * statement is not recommended. Instead, select data from particular columns using the [COLUMN[n] syntax]({{site.baseurl}}/docs/querying-plain-text-files), and then assign meaningful column
+names using aliases. For example:
+
+ CREATE TABLE parquet_users AS SELECT CAST(COLUMNS[0] AS INT) AS user_id,
+ COLUMNS[1] AS username, CAST(COLUMNS[2] AS TIMESTAMP) AS registration_date
+ FROM `users.csv1`;
+
+You need to select particular columns instead of using SELECT * for performance reasons. Drill reads CSV, TSV, and PSV files into a list of
+VARCHARS, rather than individual columns. While parquet supports and Drill reads lists, as of this release of Drill, the read path for complex data is not optimized.
+
+### Cast data
+
+You can also improve performance by casting the VARCHAR data to INT, FLOAT, DATETIME, and so on when you read the data from a text file. Drill performs better reading fixed-width than reading VARCHAR data.
+
+### Use a Distributed File System
+Using a distributed file system, such as HDFS, instead of a local file system to query the files also improves performance because currently Drill does not split files on block splits.
+
+## Configuring Drill to Read Text Files
+In the storage plugin configuration, you can set the following attributes that affect how Drill reads CSV, TSV, PSV (comma-, tab-, pipe-separated) files. ["List of Attributes and Definitions"]({{site.baseurl}}/docs/plugin-configuration-basics/#list-of-attributes-and-definitions):

-parent: "Release Notes"
----
-
-Apache Drill 0.5.0, the first beta release for Drill, is designed to help
-enthusiasts start working and experimenting with Drill. It also continues the
-Drill monthly release cycle as we drive towards general availability.
-
-The 0.5.0 release is primarily a bug fix release, with [more than 100 JIRAs](h
-ttps://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12313820&versi
-on=12324880) closed, but there are some notable features. For information
-about the features, see the [Apache Drill Blog for the 0.5.0
-release](https://blogs.apache.org/drill/entry/apache_drill_beta_release_see).
-
-This release is available as [binary](http://www.apache.org/dyn/closer.cgi/inc
-ubator/drill/drill-0.5.0-incubating/apache-drill-0.5.0-incubating.tar.gz) and
-[source](http://www.apache.org/dyn/closer.cgi/incubator/drill/drill-0.5.0-incu
-bating/apache-drill-0.5.0-incubating-src.tar.gz) tarballs that are compiled
-against Apache Hadoop. Drill has been tested against MapR, Cloudera, and
-Hortonworks Hadoop distributions. There are associated build profiles and
-JIRAs that can help you run Drill against your preferred distribution.
-
-Apache Drill 0.5.0 Key Notes and Limitations
-
- * The current release supports in memory and beyond memory execution. However, you must disable memory-intensive hash aggregate and hash join operations to leverage this functionality.
- * While the Drill execution engine supports dynamic schema changes during the course of a query, some operators have yet to implement support for this behavior, such as Sort. Others operations, such as streaming aggregate, may have partial support that leads to unexpected results.
- * There are known issues with joining text files without using an intervening view. See [DRILL-1401](https://issues.apache.org/jira/browse/DRILL-1401) for more information.

+title: "Apache Drill 1.1.0 Release Notes"
+parent: "Release Notes"
+---
+
+It has been about 6 weeks since the release of Drill 1.0.0. Today we're happy to announce the availability of Drill 1.1.0, providing 119 additional enhancements and bug fixes.
+
+## Noteworthy New Features in Drill 1.1.0
+
+Drill now supports window functions, automatic partitioning, and Hive impersonation.
+
+### [Ranking Window Functions]({{site.baseurl}}/docs/ranking-window-functions/)
+
+* ROW_NUMBER
+* RANK
+* DENSE_RANK
+* PERCENT_RANK
+* CUME _DIST
+
+### [Aggregate Window Functions]({{site.baseurl}}/docs/aggregate-window-functions/)
+
+* COUNT
+* SUM
+* MIN
+* MAX
+* AVG
+
+### [Automatic Partitioning]({{site.baseurl}}/docs/partition-pruning/#automatic-partitioning) in CTAS (DRILL-3333)
+
+When a table is created with a partition by clause, the parquet writer will create separate files for the different partition values. The data will first be sorted by the partition keys, and the parquet writer will create a new file when it encounters a new value for the partition columns.
+
+When queries are issued against data that was created this way, partition pruning will work if the filter contains a partition column. Unlike directory-based partitioning, no view is required, nor is it necessary to reference the dir* column names.
+
+### [Hive impersonation]({{site.baseurl}}/docs/configuring-user-impersonation-with-hive-authorization) support (DRILL-3203)
+
+When impersonation is enabled, Drill now supports impersonating the user who issued the query when accessing Hive metadata/data (instead of accessing Hive as the user that started the drillbit).

-title: "Apache Drill 0.4.0 Release Notes"
-parent: "Release Notes"
----
-The 0.4.0 release is a developer preview release, designed to help enthusiasts
-start to work with and experiment with Drill. It is the first Drill release
-that provides distributed query execution.
-
-This release is built upon [more than 800
-JIRAs](https://issues.apache.org/jira/browse/DRILL/fixforversion/12324963/).
-It is a pre-beta release on the way towards Drill. As a developer snapshot,
-the release contains a large number of outstanding bugs that will make some
-use cases challenging. Feel free to consult outstanding issues [targeted for
-the 0.5.0
-release](https://issues.apache.org/jira/browse/DRILL/fixforversion/12324880/)
-to see whether your use case is affected.
-
-To read more about this release and new features introduced, please view the
-[0.4.0 announcement blog
-entry](https://blogs.apache.org/drill/entry/announcing_apache_drill_0_4).
-
-The release is available as both [binary](http://www.apache.org/dyn/closer.cgi
-/incubator/drill/drill-0.4.0-incubating/apache-drill-0.4.0-incubating.tar.gz)
-and [source](http://www.apache.org/dyn/closer.cgi/incubator/drill/drill-0.4.0-
-incubating/apache-drill-0.4.0-incubating-src.tar.gz) tarballs. In both cases,
-these are compiled against Apache Hadoop. Drill has also been tested against
-MapR, Cloudera and Hortonworks Hadoop distributions and there are associated
-build profiles or JIRAs that can help you run against your preferred
-distribution.
-
-Some Key Notes & Limitations
-
- * The current release supports in memory and beyond memory execution. However, users must disable memory-intensive hash aggregate and hash join operations to leverage this functionality.
- * In many cases,merge join operations return incorrect results.
- * Use of a local filter in a join “on” clause when using left, right or full outer joins may result in incorrect results.
- * Because of known memory leaks and memory overrun issues you may need more memory and you may need to restart the system in some cases.
- * Some types of complex expressions, especially those involving empty arrays may fail or return incorrect results.
- * While the Drill execution engine supports dynamic schema changes during the course of a query, some operators have yet to implement support for this behavior (such as Sort). Others operations (such as streaming aggregate) may have partial support that leads to unexpected results.
- * Protobuf, UDF, query plan interfaces and all interfaces are subject to change in incompatible ways.
- * Multiplication of some types of DECIMAL(28+,*) will return incorrect result.
