ASF subversion and git services commented on QPID-7830: ------------------------------------------------------- Commit a4ade5a371eefdee764a6e13341625a945d67d1b in qpid-broker-j's branch refs/heads/7.0.x from [~alex.rufous] [ https://git-wip-us.apache.org/repos/asf?p=qpid-broker-j.git;h=a4ade5a ] QPID-7830: [Broker-J] Simplify string caching functionality (cherry picked from commit 57bda83de7fbe6291aea507b5c1098fda5cf130d) > [Broker-J] Heap dominated by duplicates of common routing values / header > values etc > ------------------------------------------------------------------------------------ > > Key: QPID-7830 > URL: https://issues.apache.org/jira/browse/QPID-7830 > Project: Qpid > Issue Type: Bug > Components: Broker-J > Reporter: Keith Wall > Assignee: Alex Rudyy > Priority: Major > Fix For: qpid-java-broker-7.1.0, qpid-java-broker-7.0.4 > > Attachments: > 0001-QPID-7830-Broker-J-Simplify-string-caching-functiona.patch > > > When used for store and forwarding, in some use cases the Broker's heap can > become dominated by duplicates of common values such as routing information > (e.g. {{amq.direct}} or an application's queue name) or common header values > (e.g a application/octet-stream or an application's user id). > On the 0-8..0-91 paths, every enqueued message gets its own > {{MessagePublishInfo}} referencing its own {{AMQShortString}} exchange and > routing keys. For some use-cases, these are drawn from a small set. On the > AMQP 1.0 path, {{Properties#to}} is an example. 0-10 is probably affected > too. > This unnecessarily increases the heap requirements of the Broker. > The Broker should adopt a sensible intern/caching policy with the same policy > applying regardless of whether messages follow the on-line enqueue or > recovery path. Note that in AMQP 1.0, values which are {{Symbols}} have > their underlying String automatically interned. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
