Subject Sizing walog area
Date Wed, 23 Oct 2013 17:02:34 GMT
Greetings all,
For Accumulo 1.4 where write ahead logs are not yet stored in HDFS, does
anyone have guidancewith respect to sizing the walog area?  What exactly
triggers when write ahead logs get removed?  What might cause them to hang
around for an extended period of time (as in under abnormal circumstances)?

The system this applies to will see an ingest rate of approximately 2000
docs per second averaging 1-2K each (broken out into 12 columns each, so
24,000 entries per second) across 6 tabletserver nodes.

Thanks in advance,
