SH query execution migrated from SH::init() into create_SH().
There is a session variable columnstore_processing_handlers_fallback
that allows to fallback to DH, GBH if SH fails. DH now uses semantic
tree check for unsupported features to allow to fallback to GBH or
storage API.
Fixes GBH related bug when create_GBH() returns a handler for
queries with impossible WHERE/HAVING.
Fixed bug in FromSubquery::transform() where isUnion is set to true.
Enabled RTTI b/c server team enabled it for MDB.
Removed unused code supposed to be used with vtable.
to avoid accedental crashes.
Add check for Conversion of Big IN Predicates Into Subqueries optimization
conditions.
Enabled derivedTableOptimization() for group by and derived handlers.
Disabled Conversion of Big IN Predicates Into Subqueries optimization.
Disabled most of optimizer_flags for now.
RowGroup + operator now correctly sets useStringTable flag that
instructs code to check StringStore instead of plain data buffer.
SELECT_LEX had been moved in THD so changed all references.
Avoid writing CS decimal scales into MDB decimal fields
d-only dec attribute. WIP
Replaced infinidb_vtable with a singleton MIGR.
Merged with MCOL-2121.
Added new wsrep include paths needed by UDaF code.
Removed .vcxproj from Connector code.
Legacy system vars with names infinidb_* was preserved for
backward compatibility and they will be used if
columnstore_use_legacy_vars variable is set.
Remove unused structure and plugin variable.
