HA_PARTITION_FUNCTION_SUPPORTED indicates that the function is

655

supported at all.

656

HA_FAST_CHANGE_PARTITION means that optimised variants of the changes

657

exists but they are not necessarily done online.

658

659

HA_ONLINE_DOUBLE_WRITE means that the handler supports writing to both

660

the new partition and to the old partitions when updating through the

661

old partitioning schema while performing a change of the partitioning.

662

This means that we can support updating of the table while performing

663

the copy phase of the change. For no lock at all also a double write

664

from new to old must exist and this is not required when this flag is

665

set.

666

This is actually removed even before it was introduced the first time.

667

The new idea is that handlers will handle the lock level already in

668

store_lock for ALTER Table partitions.

669

670

HA_PARTITION_ONE_PHASE is a flag that can be set by handlers that take

671

care of changing the partitions online and in one phase. Thus all phases

672

needed to handle the change are implemented inside the storage engine.

673

The storage engine must also support auto-discovery since the frm file

674

is changed as part of the change and this change must be controlled by

675

the storage engine. A typical engine to support this is NDB (through

676

WL #2498).
