[Laurynas Biveinis (laurynas-biveinis)]

    - 151: "SHOW TEMPORARY TABLES has been removed, and its
      functionality ..."
    - For InnoDB METRICS, please point to monitor names, there are
      many of them.
    - innodb_dict_tables parent feature has been replaced by the
      Oracle 5.6 feature.
    - It is not fully correct to say that 1/10 s loop variables were
      replaced by active loops etc as these are not direct
      replacements. Rather, the new InnoDB master thread behaviour
      makes old variables redundant and introduces some new ones.
    - Innodb_master_thread_background_loops needs to be checked
      whether it was removed because it simply does not have any
      sense in 5.6.
    - binlog commit feature has been ported to 5.6, but without the
      variables Please check docs elsewhere too if they have to be
      updated.
    - re. system variables, I'd replace "variable hasn't been ported"
      with something that says feature owning that variable has not
      been ported etc. But need to phrase better.
    - innodb_adaptive_hash_index_partitions "has not been ported yet"
    - blocking buffer pool restore does not have a direct replacement
      in MySQL 5.6, it's a bug/feature request (crossref with one)
    - for the 5.5 dictionary size feature replaced with Oracle
      feature, please also see http://bugs.mysql.com/bug.php?id=69519
      and describe/link to docs as necessary.
    - innodb_fast_checksum needs upgrade description.
    - please remove "yet" from ibuf variables.
    - MySQL transactional slave logs needs MySQL doc link.
    - innodb_use_sys_stats_table replacement is InnoDB 5.6 persistent
      stats.

review: Needs Fixing

[Laurynas Biveinis (laurynas-biveinis)]

    - My previous review comment re. Com_show_temporary_tables is not
      addressed. Currently it is unclear what "Information" is the
      text referring to.
    - Re. INNODB_METRICS, please point not to the module but to the
      monitor, see the table in Oracle docs that lists
      adaptive_hash_pages_added etc.
    - I suggest to add wording next to 5.6 table_definition_cache to
      explain that this variable has a new extra meaning in 5.6 for
      InnoDB, as otherwise both its presence in the earlier versions
      and its name are counterintuitive.

review: Needs Fixing

[Laurynas Biveinis (laurynas-biveinis)]

    - What is the relation between innodb-fast-index-creation and
      innodb-fast-checksums? Won't the latter, when enabled on 5.5,
      prevent any in-place upgrade to 5.6, regardless of
      innodb-fast-index-creation?
    - Line 151: s/about this/about temporary tables
    - I Innodb_adaptive_hash_cells -> adaptive_hash_rows_added mapping
      is not correct. The hash cells variable counts the internal
      hash table size and the hash table uses link chaining, thus no
      relation to the "rows" which are the logical data entries stored
      there. (probably related to data rows but unable to check right
      now).
    - Likewise Innodb_adaptive_hash_heap_buffers is accounting hash
      table memory usage, while adaptive_hash_pages_added is
      accounting the number hash-indexed buffer pool data pages.
    - Line 253, 255: s/upstream/the upstream.

review: Needs Fixing

[Laurynas Biveinis (laurynas-biveinis)]

- What does " In this case ``ALTER TABLE`` won't work due to its implementation." mean in line 50?
- Line 208: s/in the future/in a future

review: Needs Fixing

[Laurynas Biveinis (laurynas-biveinis)]

Line 50: replace "dump/imported" with "dumped and imported". No need for a new review with this change.

+|Percona Server| 5.6 is based on |MySQL| 5.6 and incorporates many of the improvements found in |Percona Server| 5.5.
+
+Features removed from |Percona Server| 5.6 that were available in |Percona Server| 5.5
+=======================================================================================
 
 Some features that were present in |Percona Server| 5.5 have been removed in |Percona Server| 5.6. These are:
 
- * `fast_index_creation <http://www.percona.com/doc/percona-server/5.5/management/innodb_fast_index_creation.html>`_ (use MySQL 5.6's ALGORITHM= option instead)
- * `HandlerSocket <http://www.percona.com/doc/percona-server/5.5/performance/handlersocket.html>`_ (may return when HandlerSocket supports MySQL 5.6)
- * SHOW [GLOBAL] TEMPORARY TABLES functionality is now only available via the INFORMATION_SCHEMA tables :table:`TEMPORARY_TABLES` and :table:`GLOBAL_TEMPORARY_TABLES`.
+ * `HandlerSocket <http://www.percona.com/doc/percona-server/5.5/performance/handlersocket.html>`_ (This feature will be ported in one of the future |Percona Server| 5.6 releases)
+ * ``SHOW [GLOBAL] TEMPORARY TABLES`` functionality is now only available via the ``INFORMATION_SCHEMA`` tables :table:`TEMPORARY_TABLES` and :table:`GLOBAL_TEMPORARY_TABLES`.
  * `InnoDB timer-based Concurrency Throttling <http://www.percona.com/doc/percona-server/5.5/performance/innodb_thread_concurrency_timer_based.html>`_
  * `InnoDB Recovery Stats <http://www.percona.com/doc/percona-server/5.5/management/innodb_recovery_patches.html>`_
  * Rows_read counters in :ref:`slow_extended` and ``SHOW PROCESSLIST`` had a very fuzzy meaning so they were removed.
 
+Replaced features that were present in |Percona Server| 5.5
+===========================================================
+
 Some features that were present in |Percona Server| 5.5 have been replaced by a different implementation of the same/similar functionality in |Percona Server| 5.6. These are:
 
  * ``SHOW ENGINE INNODB STATUS`` section "OLDEST VIEW" has been replaced by the :table:`XTRADB_READ_VIEW` INFORMATION_SCHEMA table.
  * ``SHOW ENGINE INNODB STATUS`` sections on memory usage for InnoDB/XtraDB hash tables has been replaced by the :table:`XTRADB_INTERNAL_HASH_TABLES` INFORMATION_SCHEMA table.
  * The :table:`INNODB_RSEG` table has been renamed to :table:`XTRADB_RSEG`.
 
-Some |Percona Server| 5.5 features have been replaced by similar or equivalent MySQL 5.6 features, so we now keep the MySQL 5.6 implementations in |Percona Server| 5.6. These are:
-
- * `Show Lock Names <http://www.percona.com/doc/percona-server/5.5/diagnostics/innodb_show_lock_names.html>`_ has been replaced by PERFORMANCE_SCHEMA

  * `InnoDB Data Dictionary Size Limit <http://www.percona.com/doc/percona-server/5.5/management/innodb_dict_size_limit.html>`_ has been replaced by |MySQL| 5.6 using the existing table-definition-cache variable to limit the size of the |InnoDB| data dictionary.

  * The |InnoDB| data dictionary INFORMATION_SCHEMA tables have been superseded by the |MySQL| implementations
