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.
MariaDB 10.4 only allows the system root user to log in as the root DB
user. This means the SQL commands to install the plugins won't run on a
non-root install. This patch skips the grant tables for plugin install
and does some workarounds to get the plugins in.
* 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
