We preserve union related condition blocks until UNION-capable smart handler.
Removed a number of commented code blocks.
Add projection list REAL and TIME constants, e.g
SELECT TIME'10:20:30', TIMESTAMP'2001-01-01 10:20:30', DATE'2001-01-01' FROM cs1;
Marked potentially useless block in ORDER BY processing for future removal.
Removed string variables used for reconstructed query in the pre-1.4 fork.
Removed cp_get_plan().
GBH doesn't step in if SH processes the query.
All smart handlers now correctly processes impossible WHERE and HAVING.
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.
sortItemIsInGroupRec() now has a base case for Item_Field and this prevents unbound recursion.
Fixes fromSub() call with incorrect number of arguments.
CS now doesn't ask for statistics unless a user explicitly asks for it using calsettrace().
FromSubQuery() is no pushdown aware.
Actualize OUTER_JOIN_DEBUG section in ha_calpont_execplan.cpp
to be used with 10.4.
Enabled derivedTableOptimization() for select handler.
Fix crash in ha_calpont_impl_close_connection()
Fix leak in ci.tableMap.
Removed extra returns in pushdown_init to avoid crashes.
create_select_handler now detects INSERT..SELECT.
buildConstColFromFilter now uses any kind of filter to supply
relevant columns.
Remove strings used by vtable redo phase.
Make FromSubQuery aware of Pushdown handlers.
Changed debug_walk to work around changed Item framework.
Temporary disabled derived handler and unsupported features checks.
Used Item attribute getters introduced by 10.4
Make changes to support Item::CONST_ITEM introduced by 10.4
as a replacement for INT_,REAL_,STRING_ ITEM.
Replaced QT_INFINIDB_DERIVED and similar flags
with correponded flags for Item->print().
Replaced or commented out infinidb_ variable names with columnstore_
where applicable.
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.
Renamed isInfiniDB() into isMCSTable
Changed getSelectPlan() to reuse it with derived and
other handler types.
Separate pushdown handlers methods and functions.
Removed vcxproj files from the source.
Added fix for MCOL-2166.
Merged with MCOL-2121
A view calling a view as part of a subquery outer join was not getting
the view name for the derived table columns. Which caused ColumnStore to
think it was joining outside of the view and triggered a missing column
error.
This fix adds the view name from the subquery if one cannot be obtained
from the field object.
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.
The problem was in processing a subquery in the where clause that was categorized as a
CACHE_ITEM in the parse tree. The fix involved how we walk the parse tree in gp_walk().
