BELUGA BEHR created HBASE-19682: ----------------------------------- Summary: Use Collections.emptyList() For Empty List Values Key: HBASE-19682 URL: https://issues.apache.org/jira/browse/HBASE-19682 Project: HBase Issue Type: Improvement Components: hbase Affects Versions: 3.0.0 Reporter: BELUGA BEHR Priority: Minor
Use {{Collection.emptyList()}} for returning an empty list instead of {{return new ArrayList<> ()}}. The default constructor creates a buffer of size 10 for _ArrayList_ therefore, returning this static value saves on some memory and GC pressure and saves time not having to allocate a new internally buffer for each instantiation. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
