Hi Kevin
I am very much interested to see this. We have done something similar
internally but along with the new coprocessor hooks that we added, we also
tweaked a bit on the kernel side.
It is something like,

Hi All
When we try to build any type of secondary indices for a given table how can
one handle maxVersions in the secondary index tables.
For eg,
I have inserted
Row1 - Val1 = t
Row1 - Val2 = t+1
Row1 - Val3. = t+2
Ideally if my max versions is only one then Val3 should be my
Ram,
If I understand correctly, I think you can design your index such that you
don't actually use the timestamp (e.g. everything gets put with a TS = 10 -
or some other non-special, relatively small number that's not 0 as I'd
worry about that in HBase ;) Then when you set maxVersions to 1,
Hi Jesse
Thanks lot for your reply.
- Not maintaining timestamps in the sec index may cause problems when I
issue an delete on the main table and the corresponding things needs to be
deleted in the sec index.
- As in the case I mentioned below
Index table will have
Val1_row1 (t)
Val2_row1 (t+2)

What about writing a marker (a file) into the region at split (from
preSplit) which is then existence checked and read at open (postOpen)? This
file would contain whatever indexing metadata is required.
Also, splits are nearly instant because the daughters are created with
reference files to the
Never mind, I went to look at the code. Should have done that first.
Looking at 0.94 sources, in SplitTransaction, first we notify the master
that the split has happened, and wait for the master to process it (which
opens daughters), and then call up to the CP with the daughter regions as

Thanks for sharing a pointer to your implementation.
My two cents:
timestamp is a way to do MVCC and setting every KV with the same TS will
get concurrency control very tricky and error prone, if not impossible

I think this discussion should be on HBASE JIRA.
Another dimension to secondary indexing is the co-location (or pairing) of
data table region and index table region. Related regions from the two
tables should be placed on the same region server.

I think we should revive secondary indexes discussion (actually it has been

Since Ramkrishna has design in mind, he would be the best person to log a
new JIRA.

Hi
As per Andrew the postSplit needs to move up before even the transitioning
of the ZK nodes are done. But in case of splits it is like if the META is
updated with the updated daughter info, the clients will tend to send in the
data to those updated regions.
So it is better we can add a new
