ctdbGetTableStatus

Declaration

ULONG ctdbGetTableStatus(CTHANDLE Handle);

Description

Retrieves the table status. The table status indicates which rebuild action will be taken by an alter table operation.

Return Values

Returns CTDB_REBUILD_NONE if the table is not changed or a bit mask of the values below describing the table status.

The possible rebuild status returns are:

Rebuild Status Value	Rebuild Status Symbolic Code	Explanation
0	CTDB_REBUILD_NONE	Nothing to be done, no changes to table
1	CTDB_REBUILD_DODA	Update the table DODA
2	CTDB_REBUILD_RESOURCE	Update table FC!DFLD resource
4	CTDB_REBUILD_INDEX	Add new indices to table
8	CTDB_REBUILD_ALL	Rebuild all indices
16	CTDB_REBUILD_FULL	Full table rebuild. A temporary table is created and all data is moved to new table and the indexes are built on the fly.

Example

ULONG status = ctdbGetTableStatus(hTable);

if (status & CTDB_REBUILD_ALL || status & CTDB_REBUILD_FULL)

ctdbAlterTable(hTable, CTDB_ALTER_FULL)

else if (status)

ctdbAlterTable(hTable, CTDB_ALTER_NORMAL);
