PARTITION BY SYSTEM_TIME INTERVAL ...
...
Lots of changes:
* calculate the current history partition in ::external_lock(),
not in ::write_row() or ::update_row()
* remove dynamically collected per-partition row_end stats
* no full table scan in open_table_from_share to calculate these
stats, no manual MDL/thr_locks in open_table_from_share
* no shared stats in TABLE_SHARE = no mutexes or condition waits when
calculating current history partition
* always compare timestamps, don't convert them to MYSQL_TIME
(avoid DST ambiguity, and it's faster too)
* correct interval handling, 1 month = 1 month, not 30 * 24 * 3600 seconds
* save/restore first partition start time, and count intervals from there
* only allow to drop first partitions if INTERVAL
* when adding new history partitions, split the data in the last history
parition, if it was overflowed
* show partition boundaries in INFORMATION_SCHEMA.PARTITIONS

Timestamp-based versioning for InnoDB [ closes #209 ]
...
* Removed integer_fields check
* Reworked Vers_parse_info::check_sys_fields()
* Misc renames
* versioned as vers_sys_type_t
* Removed versioned_by_sql(), versioned_by_engine()
versioned() works as before;
versioned(VERS_TIMESTAMP) is versioned_by_sql();
versioned(VERS_TRX_ID) is versioned_by_engine().
* create_tmp_table() fix
* Foreign constraints for timestamp-based
* Range auto-specifier fix
* SQL: 1-row partition rotation fix [fixes #260 ]
* Fix 'drop system versioning, algorithm=inplace'
