New Features
Now MyRocks Storage Engine has General Availablity status.
Binary log encryption has been implemented and can be now switched on using the encrypt_binlog variable.
print_lock_wait_timeout_info variable, introduced in previous release, but undocumented, allows to log information about all lock wait timeout errors.
Bugs Fixed
Intermediary slave with Blackhole storage engine couldn’t record updates from master to its own binary log in case of activated informational row-based logging. Bug fixed #1722789
Help command provided a link to an older version of the Percona Server manual. Bug fixed #1708073
A regression in the mysqld_safe script prevented to stop MySQL service correctly. Bugs fixed #1738742
Blackhole storage engine was incompatible with newer length limit of the InnoDB index key prefixes. Bug fixed #1733049
Heartbeats received by slave were reacted with mysql.slave_master_info table sync on each of them, causing huge increase in write load Bug fixed #1708033
MyRocks Changes
The replication writebatch functionality has been removed from Percona Server 5.7 due to unsafety of the current implementation.
Variables rocksdb_block_cachecompressed_hit, rocksdb_block_cachecompressed_miss, and rocksdb_getupdatessince_calls were renamed to rocksdb_block_cache_compressed_hit, rocksdb_block_cache_compressed_miss, and rocksdb_get_updates_since_calls respectively.
