Changes in AliSQL 5.6.32 (2016 11 11)

AliSQL 5.6.32 Release Notes (2016-11-11)

Abstract

About the table definition, server def(.FRM), data file(.IBD), InnoDB data dictionary maybe not consistent occasionally. So we supply a way to force clear the data.

Functionality Added or Changed

1. Support force drop table

Description:
Usually the meta data is not consistent between server layer and InnoDB layer.
So we supply a new syntax to clear the meta data.

Parameters:

no

Usage:

1. DROP TABLE FORCE t1;
2. ALTER TABLE t1 DROP PARTITION force p2;

2. TokuDB hot backup support

Description:
AliSQLBackup depends on tokudb_checkpoint_lock to implement hot backup, but invoking ft_close() to a FT file during backup will break the consistency between this FT and the others in the final backup directory. So when checkpoint lock is held by backup session, ft_close() should be skipped.

Parameters:

no

Usage:

no
