- Explain what query optimiser support for the clustering keys means: the query optimiser will avoid primary clustered index reads and replace them by secondary clustered index reads in certain scenarios.
- Before the full supported syntax, add a few basic examples of CREATE TABLE etc.
- It would be very nice to have an example with a differing query plan for the same query with regular and with clustering secondary key. Might be possible to ask Tokutek for what would be a flagship example, or maybe there is an example in their docs.

In the sample CREATE TABLE, define a primary key too for clarity
The query plans with clustering and regular secondary index are identical (except for index name and row estimate).

29+=====================================
30+ Metrics for scalability measurement
31+=====================================
32+
33+|Percona Server| has implemented extra scalability metrics in :rn:`5.6.17-65.0`. These metrics allow using Little's Law, queueing theory, and Universal Scalability Law to gain insights into server performance. This feature is implemented as a plugin.
34+
35+Installation
36+============
37+
38+Scalability Metrics plugin is shipped with |Percona Server|, but it is not installed by default. To enable the plugin you must run the following command:
39+
40+.. code-block:: mysql
41+
42+ INSTALL PLUGIN scalability_metrics SONAME 'scalability_metrics.so';
43+
44+You can check if the plugin is loaded correctly by running:
45+
46+.. code-block:: mysql
47+
48+ SHOW PLUGINS;
49+
50+The plugin should be listed in the output:

218+
219+==================
220+ Audit Log Plugin
221+==================
222+
223+Percona Audit Log Plugin provides monitoring and logging of connection and query activity that were performed on specific server. Information about the activity will be stored in the XML log file where each event will have its ``NAME`` field, it's own unique ``RECORD_ID`` field and a ``TIMESTAMP`` field. This implementation is alternative to the `MySQL Enterprise Audit Log Plugin <dev.mysql.com/doc/refman/5.5/en/audit-log-plugin.html>`_
224+
225+Audit Log plugin produces the log of following events:
226+
227+* **Audit** - Audit event indicates that audit logging started or finished. ``NAME`` field will be ``Audit`` when logging started and ``NoAudit`` when logging finished. Audit record also includes server version and command-line arguments.
228+
229+Example of the Audit event: ::
230+
231+ <AUDIT_RECORD
232+ "NAME"="Audit"
233+ "RECORD"="1_2014-04-29T09:29:40"
234+ "TIMESTAMP"="2014-04-29T09:29:40 UTC"

237+ "OS_VERSION"="x86_64-debian-linux-gnu",
238+ />
239+
240+* **Connect**/**Disconnect** - Connect record event will have ``NAME`` field ``Connect`` when user logged in or login failed, or ``Quit`` when connection is closed. Additional fields for this event are ``CONNECTION_ID``, ``STATUS``, ``USER``, ``PRIV_USER``, ``OS_LOGIN``, ``PROXY_USER``, ``HOST``, and ``IP``. ``STATUS`` will be ``0`` for successful logins and non-zero for failed logins.
241+
242+Example of the Disconnect event: ::
243+
244+ <AUDIT_RECORD
245+ "NAME"="Quit"
246+ "RECORD"="24_2014-04-29T09:29:40"
247+ "TIMESTAMP"="2014-04-29T10:20:13 UTC"

253+ "PROXY_USER"=""
254+ "HOST"=""
255+ "IP"=""
256+ "DB"=""
257+ />
258+
259+* **Query** - Additional fields for this event are: ``COMMAND_CLASS`` (values come from the ``com_status_vars`` array in the :file:`sql/mysqld.cc`` file in a MySQL source distribution. Examples are ``select``, ``alter_table", "create_table", etc.), ``CONNECTION_ID``, ``STATUS`` (indicates error when non-zero), ``SQLTEXT`` (text of SQL-statement, statements are rewritten to exclude passwords by default, this can be changed by :option:`--log-raw` option ), ``USER``, ``HOST``, ``OS_USER``, ``IP``. Possible values for the ``NAME`` name field for this event are ``Query``, ``Prepare``, ``Execute``, ``Change user``, etc.
260+
261+Example of the Query event: ::
262+
263+ <AUDIT_RECORD
264+ "NAME"="Query"
265+ "RECORD"="23_2014-04-29T09:29:40"

303+Log Format
304+==========
305+
306+Audit log plugin supports two formats. In one format (``OLD``) log record properties are saved as XML attributes and in the other (``NEW``) log recored properties are saved as XML tags. Audit log format can be set up with the :variable:`audit_log_format` variable.
307+
308+Example of the ``OLD`` format: ::
309+
310+ <AUDIT_RECORD
311+ "NAME"="Query"
312+ "RECORD"="2_2014-04-28T09:29:40"

318+ "USER"="root[root] @ localhost []"
319+ "HOST"="localhost"
320+ "OS_USER"=""

456+.. rn:: 5.6.17-65.0
457+
458+==============================
459+ |Percona Server| 5.6.17-65.0
460+==============================
461+
462+Percona is glad to announce the release of |Percona Server| 5.6.17-65.0 on May 6th, 2014 (Downloads are available `here <http://www.percona.com/downloads/Percona-Server-5.6/Percona-Server-5.6.17-65.0/>`_ and from the :doc:`Percona Software Repositories </installation>`).
463+
464+Based on `MySQL 5.6.17 <http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-17.html>`_, including all the bug fixes in it, |Percona Server| 5.6.17-65.0 is the current GA release in the |Percona Server| 5.6 series. All of |Percona|'s software is open-source and free, all the details of the release can be found in the `5.6.17-65.0 milestone at Launchpad <https://launchpad.net/percona-server/+milestone/5.6.17-65.0>`_.
465+
466+New Features
467+============
468+
469+ |Percona Server| now supports :ref:`scalability_metrics_plugin`.
470+
471+ |Percona Server| now supports :ref:`audit_log_plugin`.
472+
473+ |Percona Server| parser and query optimizer now support :ref:`tokudb_multiple_clustering_keys` when TokuDB engine is used.
474+
475+ Storage engine handler interface has been extended with new calls to notify the storage engine of imminent table or index scan. The calls are used by TokuDB to improve performance of these operations.
476+
477+ |Percona Server| packages are now available for *Ubuntu* 14.04.
478+
479+Bugs Fixed
480+==========
481+
482+ |Percona Server| couldn't be built with *Bison* 3.0. Bug fixed :bug:`1262439`,upstream :mysqlbug:`71250`.
483+
484+ Fixed the inadequate background LRU flushing for write workloads with |InnoDB| compression that could lead to lower performance. Bug fixed :bug:`1295268`.
485+
486+ |Percona Server| debug packages were not built for the previous releases. Bug fixed :bug:`1298352`.
487+
488+ Queries that no longer exceed :variable:`long_query_time` were written to the slow query log if they matched the previous :variable:`long_query_time` value when :variable:`slow_query_log_use_global_control` variable was set to ``all``. Bug fixed :bug:`1016991`.
489+
490+ When writing audit plugins it was not possible to get notifications for general-log events without enabling the general-log. Bug fixed :bug:`1182535` (upstream :mysqlbug:`60782`).
491+
492+ ``mysqld_safe`` did not correctly parse :variable:`flush_caches` and :variable:`numa_interleave` options. Bug fixed :bug:`1231110`.
493+
494+ :ref:`threadpool` would handle a new client connection without notifying Audit Plugin. Bug fixed :bug:`1282008`.
495+
496+ Fixed a performance issue in extending tablespaces if running under ``fusionIO`` with :ref:`atomic writes <atomic_fio>` enabled. Bug fixed :bug:`1286114` (*Jan Lindström*).
497+
498+ Previous implementation of the :variable:`log_slow_rate_type` set to ``query`` with :variable:`log_slow_rate_limit` feature would log every nth query deterministically instead of each query having a 1/n probability to get logged. Fixed by randomly selecting the queries to be logged instead of logging every nth query. Bug fixed :bug:`1287650`.
499+
500+ |Percona Server| source files were referencing *Maatkit* instead of |Percona Toolkit|. Bug fixed :bug:`1174779`.
501+
502+ Maximum allowed value for :variable:`log_slow_rate_limit` was ``ULONG_MAX`` (ie. either ``4294967295`` or ``18446744073709551615``, depending on the platform). As it was unreasonable to configure the slow log for every four billionth session/query, new maximum allowed value is set to ``1000``. Bug fixed :bug:`1290714`.
503+
504+Other bugs fixed :bug:`1295523`, :bug:`1299688` (upstream :mysqlbug:`72163`) and :bug:`1272732`.

525+
526+==========================
527+ Multiple Clustering Keys
528+==========================
529+
530+TokuDB allows a secondary key to be defined as a clustering key. This means that all of the columns in the table are clustered with the secondary key. |Percona Server| parser and query optimizer support Multiple Clustering Keys when TokuDB engine is used. This means that the query optimizer will avoid primary clustered index reads and replace them by secondary clustered index reads in certain scenarios.
531+
532+The parser has been extended to support following syntax:
533+
534+.. code-block:: mysql
535+
536+ CREATE TABLE ... ( ..., CLUSTERING KEY identifier (column list), ...
537+ CREATE TABLE ... ( ..., UNIQUE CLUSTERING KEY identifier (column list), ...
538+ CREATE TABLE ... ( ..., CLUSTERING UNIQUE KEY identifier (column list), ...
539+ CREATE TABLE ... ( ..., CONSTRAINT identifier UNIQUE CLUSTERING KEY identifier (column list), ...
540+ CREATE TABLE ... ( ..., CONSTRAINT identifier CLUSTERING UNIQUE KEY identifier (column list), ...
541+
542+ CREATE TABLE ... (... column type CLUSTERING [UNIQUE] [KEY], ...)
543+ CREATE TABLE ... (... column type [UNIQUE] CLUSTERING [KEY], ...)
544+
545+ ALTER TABLE ..., ADD CLUSTERING INDEX identifier (column list), ...
546+ ALTER TABLE ..., ADD UNIQUE CLUSTERING INDEX identifier (column list), ...
547+ ALTER TABLE ..., ADD CLUSTERING UNIQUE INDEX identifier (column list), ...
548+ ALTER TABLE ..., ADD CONSTRAINT identifier UNIQUE CLUSTERING INDEX identifier (column list), ...
549+ ALTER TABLE ..., ADD CONSTRAINT identifier CLUSTERING UNIQUE INDEX identifier (column list), ...
550+
551+ CREATE CLUSTERING INDEX identifier ON ...
552+
553+Examples
554+========
555+
556+To create clustered index in TokuDB table, you need to add ``CLUSTERING`` keyword in front of any index that is to be created.
557+
558+* To create a clustered index while creating a new table:
559+
560+.. code-block:: mysql
561+
562+ CREATE TABLE city (city_id int PRIMARY KEY, name varchar(50), CLUSTERING KEY (citry_id)) engine=tokudb;
563+
564+* To add a clustered index on already existing table:
565+
566+.. code-block:: mysql
567+
568+ ALTER TABLE city ADD CLUSTERING INDEX clstr_key(city_id);
569+
570+or
571+
572+.. code-block:: mysql
573+
574+ CREATE CLUSTERING INDEX clstr_key ON city(city_id);
575+
