- Run TokuDB in MySQL 5.7 without any patches.
- Keep up with changes to the APIs used by storage engines.
- Experiment with MySQL 5.7 features.
- Run this version on any production system.
- MySQL 5.7 added a memory key parameter to my_malloc, my_strdup, etc. Needed to abstract these functions as tokudb_my_malloc, tokudb_my_strdup, etc.
- Set TokuDB's db type to DB_TYPE_UNKNOWN so that TokuDB's DB_TYPE_TOKUDB patch is not needed.
- Map TOKU_ZLIB to ROW_FORMAT_DEFAULT so that TokuDB's row format patch is not needed.
- Clustering keys are not supported. The clustering key patch would be needed.
- ZLIB compression is supported.
- Quicklz, LZMA compression are not supported. The row format patch would be needed.
- Online alter table is supported.
- 32 columns per key is not supported. The 32 columns per key patch would be needed.
- Auto increment any column is not supported. The auto increment patch would be needed.
- Default storage engine is InnoDB not TokuDB.
- TokuDB plugins must be manually installed.
- No mysql test patch, so TokuDB tests can not be run.
- No sql bench patch, so sql bench tests on TokuDB can not be run.
- No Tokutek backup.
- mysql with tokudb compiles
- install plugin tokudb soname 'ha_tokudb.so' works
- create tokudb table works
