Under StoreScanner KVHeap, we have only single file always and there is no comparison happening and no calls to getXXXOffset/Length there. There is get calls in StoreScanner (max 2 times) and then in SQM also we need component offset/length. But in SQM we dont do get calls on KeyValue to get offset/length. Instead we calculate there on parsing KV buffer on our own. (See code below). Then SQM is skipping these cells and so no further get calls on the cells. So in effect there is 2 times get call on rowLength and just one time on others. This makes it clear why no adv. In a real case where Cells are not skipped (and in trunk especially) there are many times call happen and mainly on rowLength.

If u see table in above comments you can see how many times each call happen on a single Cell. Those numbers are when cells are written back to client side so comes in all layes.

[jira] [Commented] (HBASE-12295) Prevent block eviction under us if reads are in progress from the BBs
[ https://issues.apache.org/jira/browse/HBASE-12295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14566406#comment-14566406 ] Anoop Sam John commented on HBASE-12295: bq.Don't these each have their own ref count? Now in our impl, ref count is incremented per scanner. So it is not like normal java ref count. When we see one HFileBlock's ref count is 2 that means there are 2 active scanners still referring to this. Those refs might be in the read path places like comparators etc and/or by cells created from this block. So if we have to make some thing like cell close() we will maintain the count incremented when a Cell is created also. This creation is at HFileScanner level. Then every cell, when closed has to decrement this count. But the disadv for this wrt perf is we will make the counter incr/decr many times. This has to be an atomic long and so there will be some cost. But more than that , the complications will be in cell filtering area etc. When the Cell is created from Scanner level, we dont know whether this cell will get eliminated. The cell can get ignored at many places (due to version/ttl/acl/visibility/filter etc etc).. All these impl has to handle the close of the cell when it is being ignored. There can be custom filters which is doing this elimination. (by filterCell(Cell) or by filterRowCells(List) ) All these has to handle the close. And filter can transform an incoming cell into another and make that to be used from then on (transformCell(Cell)) Same way CPs also can do this filtering. There is the complication which I was telling. I actually liked that idea so that changes in HRegion level can be avoided.. Then thinking more and more I landed in all these kind of practical issues...

[jira] [Created] (HBASE-13817) ByteBufferOuputStream - add writeInt support

We use StreamUtils to do this which will write each byte one after the other. So 4 write calls on Stream.(OutputSteam has only this support) With ByteBufferOuputStream we have the overhead of checking for size limit and possible grow with every write call. Internally this stream writes to a ByteBuffer. Again inside the ByteBuffer implementations there is position limit checks. If we do write these length as int in one go we can reduce this overhead. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

The idea here is that we read a hfile, and if we have the mob refs present on a cell, we verify that the corresponding mob file is present. Furthermore, we could verify if the mob value cell is present I think in this patch, we should do same things as what is done in HFileCorruptionChecker where only opening a reader to a HFile. We can file another JIRA to detect the missed mob files which needs a full table scan I am afraid (In the current implementation of HFile.main() it does the full table scan, we need resolve the reference to mob file in that scan). bq. But this tool just try create a reader on the HFiles and not really reading Cells out of it. So may be we will have the ref cell -> mob cell check as an other tool or so? Or am I missing some thing? You are right Anoop. This one is just to find all the mob files and check whether they are corrupt. We need another JIRA to check the missed mob cells. bq. But this would need a full table scan also? Are you just plan to check the integrity of the MOB files?

[jira] [Created] (HBASE-13819) Make RPC layer CellBlock buffer a DirectByteBuffer
Anoop Sam John created HBASE-13819: -- Summary: Make RPC layer CellBlock buffer a DirectByteBuffer Key: HBASE-13819 URL: https://issues.apache.org/jira/browse/HBASE-13819 Project: HBase Issue Type: Sub-task Reporter: Anoop Sam John Assignee: Anoop Sam John Fix For: 2.0.0 In RPC layer, when we make a cellBlock to put as RPC payload, we will make an on heap byte buffer (via BoundedByteBufferPool). The pool will keep upto certain number of buffers. This jira aims at testing possibility for making this buffers off heap ones. (DBB) The advantages 1. Unsafe based writes to off heap is faster than that to on heap. Now we are not using unsafe based writes at all. Even if we add, DBB will be better 2. When Cells are backed by off heap (HBASE-11425) off heap to off heap writes will be better 3. When checked the code in SocketChannel impl, if we pass a HeapByteBuffer to the socket channel, it will create a temp DBB and copy data to there and only DBBs will be moved to Sockets. If we make DBB 1st hand itself, we can avoid this one more level of copying. Will do different perf testing with changed and report back. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
