Anoop Sam John commented on HBASE-17765:
Patch looks good.
{code}
public static final String COMPACTING_MEMSTORE_THRESHOLD_KEY =
51"hbase.hregion.compacting.memstore.threshold";
{code}
Am not sure whether this name is correct. This is a threshold value for
#segments above which there will be in memory merge. So seeing this one may
not get what threshold it is. Compacting memstore will have threshold for in
memory flush also (Segment flush to pipeline)/ So pls give a better/clear name.

This JIRA intends to fixs bugs in merge and make it configurable. Under HBASE-16417 there is a discussion whether to make the merge part of the default configuration or not. This JIRA doesn't turn the merge into default.

updateRegionSize is added to swap() as new parameter - without explanation in
@param javadoc.
{code}
if (closeSuffix && region != null) {

closeSuffix above is changed to updateRegionSize in the patch.
Can you add some comment for the change ?

[ https://issues.apache.org/jira/browse/HBASE-17765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15907066#comment-15907066 ] ramkrishna.s.vasudevan commented on HBASE-17765: REading thro the patch, now since you have increased the threshold to 30, you will not do the MERGE till 30 is reached and so the data will be read from multiple segments only. But you will keep flattening the youngest segment? > Reviving the merge possibility in the CompactingMemStore > > > Key: HBASE-17765 > URL: https://issues.apache.org/jira/browse/HBASE-17765 > Project: HBase > Issue Type: Sub-task >Reporter: Anastasia Braginsky >Assignee: Anastasia Braginsky > Fix For: 2.0.0 > > Attachments: HBASE-17765-V01.patch > > > According to the new performance results presented in the HBASE-16417 we see > that the read latency of the 90th percentile of the BASIC policy is too big > due to the need to traverse through too many segments in the pipeline.

[ https://issues.apache.org/jira/browse/HBASE-17765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15907061#comment-15907061 ] Anastasia Braginsky commented on HBASE-17765: - [~anoop.hbase], in addition to what [~ebortnik] had answered you, your math is correct. 16 should be max and 30 stands there for safety. According to our recent experiments, we are not sure the default way should be no merge. But let discuss it when we publish the results. Currently the #segments in pipeline is configurable and can be any number. Pay attention that this patch also fixes the bug according to which the region server wasn't updated with the new sizes when the merge did happened. > Reviving the merge possibility in the CompactingMemStore > > > Key: HBASE-17765 > URL: https://issues.apache.org/jira/browse/HBASE-17765 > Project: HBase > Issue Type: Sub-task >Reporter: Anastasia Braginsky >Assignee: Anastasia Braginsky > Fix For: 2.0.0 > > Attachments: HBASE-17765-V01.patch > > > According to the new performance results presented in the HBASE-16417 we see > that the read latency of the 90th percentile of the BASIC policy is too big > due to the need to traverse through too many segments in the pipeline.

We create a larger segment with one index - but no data is copied. Also, we avoid using the SQM scan (more expensive), so duplicate data versions are not eliminated. Bottom line - (1) the overhead and the space savings are both between BASIC and EAGER, and (2) the tail read latency problem is solved. We'll be publishing the perf results shortly. Following that, let's collectively decide whether MERGE should be a level between BASIC and EAGER, or maybe just become the new BASIC, for simplicity.

Or it is just merge of the index data? Ya make that 30 to be configurable is fine IMO. In ur tests how much this #segments in pipeline gets to?As per the math it can not be more than 16 no? Default 128 MB flush size and 4x as blocking factor. And 25% of flush size is what the in memory flush cap.So we can have 4 * 4 segments at max in pipeline? Or my math is somewhere wrong? Accordingly the default of this config we need to adjust. IMO than a 30 value, we should do this way.. When the config values of this in memory flush factor and/or blocking factor changes, we need to adjust this new config so as to make the default way of no merge. Ya one can always change it then. > Reviving the merge possibility in the CompactingMemStore > > > Key: HBASE-17765 > URL: https://issues.apache.org/jira/browse/HBASE-17765 > Project: HBase > Issue Type: Sub-task >Reporter: Anastasia Braginsky >Assignee: Anastasia Braginsky > Fix For: 2.0.0 > > Attachments: HBASE-17765-V01.patch > > > According to the new performance results presented in the HBASE-16417 we see > that the read latency of the 90th percentile of the BASIC policy is too big > due to the need to traverse through too many segments in the pipeline.
