Robbie Gemmell updated PROTON-636: ---------------------------------- Priority: Minor (was: Major) > remove confusing default for session capacity and allow disabling it > -------------------------------------------------------------------- > > Key: PROTON-636 > URL: https://issues.apache.org/jira/browse/PROTON-636 > Project: Qpid Proton > Issue Type: Improvement > Components: proton-c > Reporter: Rafael H. Schloming > Assignee: Alan Conway > Priority: Minor > Labels: framing > Fix For: proton-c-0.23.0 > > > Original title: setting a 1MB frame size results in an undesirably small > session window) > Description, from PROTON-1739: > The session has a default 'incoming capacity' of 1MB, which actually has no > effect by default and leads to unexpected behaviour while changing other > configuration. It should be removed. > The value is used when the engine decides what incoming session window to set > on Flow frames, but only if a specific frame size is configured for the > transport, which it isn't by default. If a specific frame size is set, then > any session capacity really needs to be set based on it in order to be > appropriate, the default being fixed as it is leads to unexpectedly low > window sizes in many cases which will impact performance in unexpected ways. > Its confusing that setting frame size results in completely different > behaviour than before for another thing (window size) which perhaps hasn't > been configured at all, and the existing behaviour is also such that you cant > turn it off. -- 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
