    Percona Server for MySQL 8.0.16-7¶

    Percona announces the release of Percona Server for MySQL 8.0.16-7 on August 15, 2019 (downloads are available here and from the Percona Software Repositories). This release includes fixes to bugs found in previous releases of Percona Server for MySQL 8.0. Percona Server for MySQL 8.0.16-7 is now the current GA release in the 8.0 series. All of Percona’s software is open-source and free.

    Percona Server for MySQL 8.0 includes all the features and bug fixes available in MySQL 8.0.16 Community Edition in addition to enterprise-grade features developed by Percona.

    Encryption Features General Availability (GA)¶

    • Encrypting Temporary Files

    • Encrypting the Undo Tablespace

    • Encrypting the System Tablespace

    • default_table_encryption =OFF/ON

    • table_encryption_privilege_check=OFF/ON

    • Encrypting the Redo Log files for master key encryption only

    • Merge-sort-encryption

    • Encrypting Doublewrite Buffers

    Bugs Fixed¶

    • Parallel doublewrite buffer writes must crash the server on an I/O error occurs. Bug fixed #5678.

    • After resetting the innodb_temp_tablespace_encrypt to OFF during runtime the subsequent file-per-table temporary tables continue to be encrypted. Bug fixed #5734.

    • Setting the encryption to ON for the system tablespace generates an encryption key and encrypts system temporary tablespace pages. Resetting the encryption to OFF, all subsequent pages are written to the temporary tablespace without encryption. To allow any encrypted tables to be decrypted, the generated keys are not erased. Modifying the innodb_temp_tablespace_encrypt does not affect file-per-table temporary tables. This type of table is encrypted if ENCRYPTION =’Y’ is set during table creation. Bug fixed #5736.

    • An instance started with the default values but setting the redo-log without specifying the keyring plugin parameters does not fail or throw an error. Bug fixed #5476.

    • The rocksdb_large_prefix allows index key prefixes up to 3072 bytes. The default value is changed to TRUE to match the behavior of the innodb_large_prefix. #5655.

    • On a server with a large number of tables, a shutdown may take a measurable length of time. Bug fixed #5639.

    • The changed page tracking uses the LOG flag during read operations. The redo log encryption may attempt to decrypt pages with a specific bit set and fail. This failure generates error messages. A NO_ENCRYPTION flag lets the read process safely disable decryption errors in this case. Bug fixed #5541.

    • If large pages are enabled on MySQL side, the maximum size for innodb_buffer_pool_chunk_size is effectively limited to 4GB. Bug fixed #5517. (Upstream 94747)

    • The TokuDB hot backup library continually dumps TRACE information to the server error log. The user cannot enable or disable the dump of this information. Bug fixed #4850.

    Other bugs fixed: #5688, #5723, #5695, #5749, #5752, #5610, #5689, #5645, #5734, #5772, #5753, #5129, #5102, #5681, #5686, #5681, #5310, #5713, #5007, #5102, #5129, #5130, #5149, #5696, #3845, #5149, #5581, #5652, #5662, #5697, #5775, #5668, #5752, #5782, #5767, #5669, #5753, #5696, #5803, #5804, #5820, #5827, #5835, #5724, #5767, #5782, #5794, #5796, #5746 and, #5748.

    Known Issues¶

    • #5865: Percona Server for MySQL 8.0.16-7 does not support encryption for the MyRocks storage engine. An attempt to move any table from InnoDB to MyRocks fails as MyRocks currently sees all InnoDB tables as being encrypted.
