Are you Okay with 0.94 patch v5 ?

 Allow coprocessor to interact with batches per region sent from a client(?)

  Issue Type: New Feature
Affects Versions: 0.95.0, 0.94.6
Reporter: Lars Hofhansl
Assignee: Anoop Sam John
 Fix For: 0.95.0, 0.94.6

 HBASE-4210_Trunk-V3.patch


 Currently the coprocessor write hooks - {pre|post}{Put|Delete} - are strictly 
 one row|cell operations.
 It might be a good idea to allow a coprocessor to deal with batches of puts 
 and deletes as they arrive from the client.

+1 on patch (both 0.94 and 0.96).

MiniBatchOperationInProgress is still a bit questionable (slightly overkill. 
IMHO, just to hide the array offset). Also this won't allow the RegionObserver 
to interfere with the batch of operations (for example removing one), but I 
guess that would be tricky anyway.

May be CP can set the status so that region can ignore the Mutation?

Not sure about MiniBatchOperationInProgress. You are halfway from starting with 
an array and ending up with the full list contract, including proper iterators. 
Why not have getters and setters take an index parameter? Then there would seem 
no need for next(), rewind(), the IllegalStateExceptions, etc.

[~apurtell] Thanks for the review and comment.
Ya it looks simple for me. Oops why I have not gone with that simplest way! :(
So when MiniBatchOperationInProgress contains operation index [5-10) and some 
one call MiniBatchOperationInProgress#getOperation(1) - we can convert it into 
BatchOperationInProgress.operations[5+1].  I read your comment correctly? This 
looks just fine with me. I will update the patch tonight.

Looks fine. Just like InternalScanner#next() returns hasNext. 
bq.Can we avoid exposing WALedits here? Because we now expose them in 
WalObserver also.
Why I have done so is, the prePut() hook allows the CP to add/change the 
WALWdit. We capture the WALEdits from CP and writing. So may be some one might 
need it?

 Allow coprocessor to interact with batches per region sent from a client(?)
 ---

 Key: HBASE-4210
 URL: https://issues.apache.org/jira/browse/HBASE-4210
 Project: HBase
  Issue Type: New Feature
Affects Versions: 0.94.0
Reporter: Lars Hofhansl
Assignee: Anoop Sam John
Priority: Minor
 Fix For: 0.96.0, 0.94.6

 Attachments: HBASE-4210_94.patch


 Currently the coprocessor write hooks - {pre|post}{Put|Delete} - are strictly 
 one row|cell operations.
 It might be a good idea to allow a coprocessor to deal with batches of puts 
 and deletes as they arrive from the client.

Got busy with some other works. Will come up with a patch next week.
Also this pre hooks for the Puts will be called after the TS for the Puts are 
populated in HRegion so the hooks can get the actual TS which will go in the 
Put. Just seen the issue raised by JD HBASE-7774

Yes Anoop.  The patch will be very useful for folks to understand what was done.

bq. The main concern is how we can pass the mutations which are handled in a 
current Mini batch.

Yes, I propose you don't do that, and instead inform the CP when a batch is 
starting, when the batch has completed, and by inclusion of an RPC id in hook 
upcalls for the individual ops in the batch, what ops below to what batch RPC 
(by ID). 

This way there is no expensive construction of a large data structure.

Using RPC ID to tie individual hooks together works.

I also do like Anoops suggestion to pass an array of operations along with 
first and last. Specifically that would be batchOp.operations, firstIndex, and 
lastIndexExclusive. That way nothing needs to be copied and we still have the 
(semi) intuitive pattern that you get an array of operations along with what 
subset of is being handled now.

The RPC ID idea is cleaner; but it is harder to use by a hook and the preHooks 
are actually all run before any batch.

I think the CP should know which all Mutations is getting applied each time. 
The batch of mutations might be running in N number of mini batches. So in 
every mini batch we need to know which all Mutations getting applied this time. 
This way only I can be make sure that I add the index for those Puts. This 
makes index 100% consistent.  This one can be achieved with RPC ID alone Andrew?

Andrew - You agree on passing the Mutation(which are getting applied in every 
MiniBatch) also to CP. Waiting a +1 from CP's boss. :)
