> Optimize unnecessary type castings in Scan and Get setter methods
> -----------------------------------------------------------------
>
> Key: HBASE-29004
> URL: https://issues.apache.org/jira/browse/HBASE-29004
> Project: HBase
> Issue Type: Improvement
> Components: Performance
> Reporter: Chandra Sekhar K
> Assignee: Chandra Sekhar K
> Priority: Major
> Labels: pull-request-available
>
> In the setter methods of Scan and Get, we invoke the super class method, type
> cast and return the object.
> {code:java}
> public Scan setColumnFamilyTimeRange(byte[] cf, long minStamp, long maxStamp)
> {
> return (Scan) super.setColumnFamilyTimeRange(cf, minStamp, maxStamp);
> }{code}
>
> In profiler reports it's observed that this typecasting does take some
> additional cpu cycles. we can optimize this by adding an explicit return
> statement with current object.
> {code:java}
> public Scan setColumnFamilyTimeRange(byte[] cf, long minStamp, long maxStamp)
> {
> super.setColumnFamilyTimeRange(cf, minStamp, maxStamp);
> return this;
> }{code}
