Ted Yu created KYLIN-3144: ----------------------------- Summary: Adopt Collections.emptyList() for empty list values Key: KYLIN-3144 URL: https://issues.apache.org/jira/browse/KYLIN-3144 Project: Kylin Issue Type: Improvement Reporter: Ted Yu Priority: Minor
Use Collection.emptyList() for returning an empty list instead of returning new ArrayList<>(). The default constructor creates a buffer of size 10 for ArrayList . Therefore, returning this static value saves some memory and lessens GC pressure. One candidate for replacement is in HybridService#listHybrids() -- This message was sent by Atlassian JIRA (v6.4.14#64029)
