Subject [jira] [Commented] (HBASE-7679) implement store file management for stripe compactions
Date Sun, 17 Mar 2013 01:10:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13604472#comment-13604472

stack commented on HBASE-7679:
------------------------------

ConcatenatedLists should have unit test.

Should this define be in the Interface or do you think it implementation specific?

+  public static final String BLOCKING_STOREFILES_KEY = "hbase.hstore.blockingStoreFiles";

This has to be public?

+  public byte[] getMetadataValue(byte[] key) {

On StripeStoreFileManager, do we know if this approach has merit?  Have we run models or actual
test runs and can see it saves i/o?  Would be interesting to know.  Do we have to commit it
to figure this out?  I can see committing all the refactorings which allow different compaction
policies but would think a compaction engine would need to have proven merit before it goes
in?  What you think Sergey?

Do we have to have a L0?  Can we not flush multiple files when we flush, one per boundary
in the region?  Was that thought just too much work flushing?
