Hi Srini, We have tried the approach what Moiz had mentioned – using CDTCN and caching data, and it was quite performant in one of our reference application. You may want to look - https://git.opendaylight.org/gerrit/#/c/45131/ Regards Muthu From: controller-dev-boun...@lists.opendaylight.or

[controller-dev] how to update the initial config after moving to blueprint

2016-09-14 Thread Mohamed ElSerngawy
Hi Team, I had struggled to update the initial configuration of the openflow plugin after starting ODL. For example: previously when we want to change the Openflow plugin port configuration (6633 to 6634) or transport-protocol (tcp to tls), we just change the values in the 42-openflowplugin-*.x

The single use ClusteredDataChange/ClusteredDataTreeChange listeners are fine and may perform better than the remote read but if you really have a lot of reads even this mechanism is expensive as there is quite a bit of overhead associated with setting up a listener. I would recommend that you

With Beryllium-SR3, I just verified using tcpdump on port 2550 that the data for the read operation at the follower came over the network from the shard leader. Is there any plan with Boron to make it a local read from the replica? On Wed, Sep 14, 2016 at 1:43 PM, Srini Seetharaman < srini.seetha

Hi Tom and Moiz Is it still the case with Beryllium and Boron that the read transactions from a follower are forwarded to the leader? Thanks Srini. On Sat, Feb 28, 2015 at 8:26 AM, Tom Pantelis wrote: > Colin, Tianzhu > > Reads are also forwarded to the leader so, yes, remote reads would take >

No. I thought there was a bug for pipe-lining but I don't see one. Initial patch in https://git.opendaylight.org/gerrit/#/c/28775/ On Wed, Sep 14, 2016 at 11:12 AM, Colin Dixon wrote: > Is it all tracked under bug 5280? > > --Colin > > > On Tue, Sep 13, 2016 at 2:18 PM, Robert Varga wrote: > >>
