> Key: HBASE-4542
> URL: https://issues.apache.org/jira/browse/HBASE-4542
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.89.20100924
> Reporter: Kannan Muthukkaruppan
> Assignee: Madhuwanti Vaidya
> Fix For: 0.94.0, 0.96.0
>
> Attachments:
> 0001-jira-HBASE-4542-Add-filter-info-to-slow-query-loggin.patch,
> Add-filter-info-to-slow-query-logging-2012-03-06_14_28_13.patch,
> D1263.2.patch, D1539.1.patch
>
>
> Slow query log doesn't report filters in effect.
> For example:
> {code}
> (operationTooSlow): \
> {"processingtimems":3468,"client":"10.138.43.206:40035","timeRange":
> [0,9223372036854775807],\
> "starttimems":1317772005821,"responsesize":42411, \
> "class":"HRegionServer","table":"myTable","families":{"CF1":"ALL"]},\
> "row":"6c3b8efa132f0219b7621ed1e5c8c70b","queuetimems":0,\
> "method":"get","totalColumns":1,"maxVersions":1,"storeLimit":-1}
> {code}
> the above would suggest that all columns of myTable:CF1 are being requested
> for the given row. But in reality there could be filters in effect (such as
> ColumnPrefixFilter, ColumnRangeFilter, TimestampsFilter() etc.). We should
> enhance the slow query log to capture & report this information.
