Jean-Daniel Cryans commented on HBASE-11120:
bq. I don't see hbase.hstore.compaction.min.size in code base any more
Yeah I was confused by this too, [~stack], until I found this thread that you
started for this reason a while back:
http://osdir.com/ml/general/2013-06/msg41068.html
Basically, {{CompactionConfiguration}} was written with a configuration
prefix so doing a grep on that config (or hbase.hstore.compaction.max.size)
won't return anything. I think we should undo the refactoring in that class
since it obviously breaks a pattern we're used to, which is to completely spell
out the configuration names so we can easily search for them.

stack commented on HBASE-11120:
---
Why did the patch go from 21k to 6k [~misty]? Did you get less ambitious?
Looking the below:
{code}
entryhbase.hstore.compaction.min.size/entry
entryA StoreFile smaller than this size (in bytes) will
always be eligible for
minor compaction./entry
-entry10/entry
+entry128 MB/entry
/row
row
entryhbase.hstore.compaction.max.size/entry
entryA StoreFile larger than this size (in bytes) will
be excluded from minor
compaction./entry
-entry1000/entry
+entryLong.MAX_VALUE/entry
{code}
... I don't see hbase.hstore.compaction.min.size in code base any more and you
can't write Long.MAX_VALUE or 128 MB as values... our configuration system
can't digest anything but numbers.
Let me know why big difference in size. Maybe this patch should have had more
in it? Thanks.

Jean-Daniel Cryans commented on HBASE-11120:
Spent some more time reading through and I saw that I had missed a few things.
BTW, thanks again Misty for working on this, it is much needed.
I'm not sure about this part:
{quote}
However, if the normal compaction
+algorithm do not find any normally-eligible StoreFiles, a
major compaction is
+the only way to get out of this situation, and is forced.
This is also called a
+size-based or size-triggered major compaction.
{quote}
The exploration compaction will select the smallest set of files to compact and
it won't trigger a major compaction. Also, I looked for size-based and
size-triggered in the code but couldn't find anything so I'm not sure what
this is referring to.
This is wrong:
{quote}
+termIf this compaction was user-requested, do a major
compaction./term
+listitem
+ paraCompactions can run on a schedule or can be initiated
manually. If a
+compaction is requested manually, it is always a major
compaction. If the
+compaction is user-requested, the major compaction still
happens even if the are
+more than varnamehbase.hstore.compaction.max/varname
files that need
+compaction./para
+/listitem
{quote}
It will do a minor compaction if the user asks for that, or a major compaction
if it's specifically asked for.
It might be good to mention that hbase.hstore.compactionThreshold was the old
name for hbase.hstore.compaction.min in this section:
{quote}
+ row
+entryhbase.hstore.compaction.min/entry
+entryThe minimum number of files which must be eligible
for compaction before
+ compaction can run./entry
+entry3/entry
+ /row
{quote}
Those two are wrong (if 1000 bytes was the max we'd probably never compact :P):
{quote}
+ row
+entryhbase.hstore.compaction.min.size/entry
+entryA StoreFile smaller than this size (in bytes) will
always be eligible for
+ minor compaction./entry
+entry10/entry
+ /row
+ row
+entryhbase.hstore.compaction.max.size/entry
+entryA StoreFile larger than this size (in bytes) will
be excluded from minor
+ compaction./entry
+entry1000/entry
+ /row
{quote}
It should be 128MB and Long.MAX_VALUE as per:

Jean-Daniel Cryans commented on HBASE-11120:
On top of Sergey's comments:
This could also use a sentence regarding TTLs, they are simply filtered out and
tombstones aren't created:

One thing bothers me about this para:
{noformat}
+paraThe compaction algorithms used by HBase have evolved over
time. HBase 0.96
+ introduced a new algorithm for compaction file selection. To
find out about the old

the new algorithm, which

xlink:href=https://issues.apache.org/jira/browse/HBASE-7842;HBASE-7842/link.
{noformat}
What's written next is much more about how to pick the files that will then be
considered for compaction than the actual new policy which is in
ExploringCompactionPolicy.java. In other words, the text that follows what I
just quoted is ok but not really new in 0.96 via HBASE-7842, and it seems to me
that we should explain what HBASE-7842 does.

[jira] [Commented] (HBASE-11120) Update documentation about major compaction algorithm
[ https://issues.apache.org/jira/browse/HBASE-11120?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=14005471#comment-14005471 ] Misty Stanley-Jones commented on HBASE-11120: - a store can only have so many files, and that's called the blocking store file count so you cannot flush data if you have too many files, you have to wait for a compaciton and you cannot insert if the memstore is over some threshold but then the compaction selection might not select a single file if none of them are good so if you get there, you're stuck that's the accounting here: boolean mayBeStuck = (candidateFiles.size() - filesCompacting.size() + futureFiles) = storeConfigInfo.getBlockingFileCount(); Jean-Daniel Cryans 10:29 am if our files we're supposed to compact, minus the ones we're already compacting, plus 1 since those files will end up being a new store file, is greater or equal to the blocking file count then we force a compacting compaction Update documentation about major compaction algorithm - Key: HBASE-11120 URL: https://issues.apache.org/jira/browse/HBASE-11120 Project: HBase Issue Type: Bug Components: Compaction, documentation Affects Versions: 0.98.2 Reporter: Misty Stanley-Jones Assignee: Misty Stanley-Jones Attachments: HBASE-11120.patch [14:20:38] jdcryans seems that there's http://hbase.apache.org/book.html#compaction and http://hbase.apache.org/book.html#managed.compactions [14:20:56] jdcryans the latter doesn't say much, except that you should manage them [14:21:44] jdcryans the former gives a good description of the _old_ selection algo [14:45:25] jdcryans this is the new selection algo since C5 / 0.96.0: https://issues.apache.org/jira/browse/HBASE-7842 -- This message was sent by Atlassian JIRA (v6.2#6252)
