Please find attached the WIP version 1 of the auto partitioning patch. There
was discussion on this a while back on -hackers at:
Please note that this patch tries to automate the activities that currently
are carried out manually. It does nothing fancy beyond that for now. There
were a lot of good suggestions, I have noted them down but for now I have
tried to stick to the initial goal of automating existing steps for
Things that this patch does:
i) Handle new syntax to provide partitioning:
CREATE TABLE tabname (
) PARTITION BY
PARTITION partition_name CHECK(...),
PARTITION partition_name CHECK(...)
ii) Create master table.
iii) Create children tables based on the number of partitions specified and
make them inherit from the master table.
The following things are TODOs:
iv) Auto generate rules using the checks mentioned for the partitions, to
handle INSERTs/DELETEs/UPDATEs to navigate them to the appropriate child.
Note that checks specified directly on the master table will get inherited
v) Based on the PRIMARY, UNIQUE information specified, pass it on to the
vi) [stretch goal] Support HASH partitions
Will try to complete the above mentioned TODOs as soon as is possible.
Comments, feedback appreciated.
Thanks and Regards,
