Subject [jira] [Commented] (HBASE-4534) A new unit test for lazy seek and StoreScanner in general
Date Tue, 04 Oct 2011 01:54:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13119869#comment-13119869
] 

Jonathan Gray commented on HBASE-4534:
--------------------------------------

LUCENE-3408 is just a wrapper around two counter implementations.  One is thread-safe and
uses an AtomicLong, the other is not and uses a long.  It looks like they were just trying
to improve performance when the counter was being used in a single thread.

+1 that we should deal with changing AtomicLong to something else in another jira.

> A randomized unit test for Gets/Scans (all-row, single-row, multi-row, all-column, single-column,
and multi-column). Also all combinations of Bloom filters and compression (NONE vs GZIP) are
tested. The unit test flushes multiple StoreFiles with disjoint timestamp ranges and runs
various types of queries against them. Currently we are not testing overlapping timestamp
ranges.
