Intro* INSERT statements could face a non-existant block when MCOL-498 feature
is enabled. writeRow() guard blocks was supposed to proactively create empty
blocks. The pre-patch logic failed when first value in the block has been
removed by DELETE and this overwrites the whole valid block with empty magics.
This patch moves proactive creation logic into allocRowId().
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.
This patch will allow MariaDB replication into UM1 when enabling the
following is added to the SystemConfig section of Columnstore.xml:
<ReplicationEnabled>Y</ReplicationEnabled>
The intended use case is to replication from an InnoDB MariaDB server
into ColumnStore. You would need to create the tables on the ColumnStore
slave as "ColumnStore" and the same tables in the master as InnoDB.
At the moment the use case is narrow and could be prone to problems so
this will use the hidden flag until we can improve it.
names that contains '/' sign in the middle. Given the name `some/table/` in to or
from. RENAME uses a prefix to the left of the first '/', namely `some` and doesn't
consider the trailer `/table/`.
doesn't crash on multi-RENAME statements when non-alphanumeric
chars are presented in table names.
Replaced INFINIDB_DEBUG with MCS_DEBUG in ha_calpont_ddl.cpp
Removed unused debug outputs.
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.
* TEXT and BLOB now have separate identifiers internally
* TEXT columns are identified as such in system catalog
* cpimport only requires hex input for BLOB, not TEXT
This does the following:
* Switch resource manager to a singleton which reduces the amount of
times the XML data is scanned and objects allocated.
* Make the I_S tables use the FE implementation of the system catalog
* Make the I_S.columnstore_columns table use the RID list cache
* Make the extentmap pre-allocate a vector instead of many small allocs
This patch allows the following syntax to change the current
autoincrement value for the table:
ALTER TABLE table_name COMMENT='autoincrement=value';
Where "value" is the new integer to be used.
