Set a proper type for string literals on ConstantColumn ctor
to fix the regression produced by MCOL-174.
Removed OPTIMIZER_SWITCH_EXISTS_TO_IN b/c MDB produces
unsupported optimization with it and CS couldn't create
ExistsFilter.
This patch:
* Moves ColumnStore my.cnf to /etc/my.cnf.d/columnstore.cnf
* Removes unneeded entries from columnstore.cnf
* Removes some things that used my.cnf and are now dead
* Also removes utils/scenarios
* Modifies things that use extra defaults file to use the standard one
* Makes sure that C++11 standard is used for older CMake versions
With this patch we no longer need to set -DINSTALL_SYSCONF2DIR and
-DINSTALL_SYSCONFDIR when building MariaDB server.
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.
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.
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
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.
Dumpcat was trying to pull in Perl's MySQL DBD as a dependency in RPM
builds. For 1.1 this causes conflicts so we can't do this. There are
alternative tools in ColumnStore to do the same thing as dumpcat.pl and
the SQL files are still there which is what the support tool uses.
* Add INFORMATION_SCHEMA.COLUMNSTORE_FILES which contains information
about files
* Remove file information from COLUMNSTORE_EXTENTS (due to above)
* Hide columns with Object ID < 3000 (internal columns)
* Fix bad calculation in data_size columns
* Fix minor memory leak
* Add compressedSize() function to IDBFileSystem to get the used file
size for a compressed file
* Add columnstore_info schema with utility stored procedures to access
the information_schema tables
This patch does the following:
* Fix a year storage issue in the datestamp for the columnstore tables
metadata table (note that any previous tables will still have the
incorrect year stored).
* Expose the table creation date in CalpontSystemCatalog::getTables()
* Add an INFORMATION_SCHEMA table listing the tables in ColumnStore
(similar to systable)
* Add an INFORMATION_SCHEMA table listing the columns in ColumnStore
(similar to syscolumn)
* Add an INFORMATION_SCHEMA table listing the extents in ColumnStore
(similar to the editem tool but with additional file information)
* Modifies the build system and scripts to support the new tables
