Dan Berindei created ISPN-12733: ----------------------------------- Summary: Cache collections toArray() is inefficient Key: ISPN-12733 URL: https://issues.redhat.com/browse/ISPN-12733 Project: Infinispan Issue Type: Bug Components: Core, Streams Affects Versions: 12.0.1.Final, 11.0.9.Final Reporter: Dan Berindei Fix For: 12.1.0.Final Cache collections do not implement {{toArray()}}, so they use the implementation from {{AbstractCloseableIteratorCollection}}, which calls first {{collection.size()}}, creates an array with the appropriate size, and then populates the array from the iterator. Calling {{stream().toArray()}} avoids the {{size()}} call, so they should also implement {{toArray()}} and use {{stream.toArray()}} internally. -- This message was sent by Atlassian Jira (v8.13.1#813001)
