This makes the code easier to read, but does not change behavior. # Conflicts: # presto-main/src/main/java/io/prestosql/dispatcher/QueuedStatementResource.java
QueuedStatementResource attempts to maintain an in-memory query cache by only expiring queries that are no longer tracked by DispatchManager. It is possible for a query to be created in QueuedStatementResource, but never submitted to DispatchManager if the client never comes back and calls getStatus() (which is the trigger for the query to be submitted to DispatchManager). To handle this, we add a timeout to purge queries from this cache if it has not been submitted by the query abandoned client timeout threshold. # Conflicts: # presto-main/src/main/java/io/prestosql/dispatcher/QueuedStatementResource.java
