#opendaylight-meeting: MD-SAL Status Call - July 15th, 2014
Meeting started by devinavery at 16:14:58 UTC
(full logs).
Meeting summary
- Status Sync (devinavery, 16:15:18)
- Toaster example updated with example async
programming (devinavery,
16:15:40)
- upcoming: Simplify WriteTransaction by changing
signature - deprecating old method adding new one (devinavery,
16:16:29)
- Colin asks if using "asyncCommit" instead of
"Ready" would make more sense to others. (devinavery,
16:16:47)
- Robert explains that "ready" means that the
transaction is "ready to submit" (devinavery,
16:17:05)
- another suggestion is to use "submit". Looking
for opinions on this call. (devinavery,
16:17:39)
- Does "submit" generally apply to
transactions? (devinavery,
16:19:46)
- Robert: Transactions which are "Ready" is well
known in transaction processing, so it really depends where we get
our vocabulary from (devinavery,
16:20:41)
- ACTION: Tom P to send
an e-mail to controller dev to get opinion on submit vs ready. Keep
open for 24 hours (devinavery,
16:22:01)
- Question about MD-SAL Clustering - colindixon
is providing a quick update (devinavery,
16:23:34)
- https://git.opendaylight.org/gerrit/#/q/status:open+topic:akka-raft,n,z
akka raft related commits (colindixon,
16:24:10)
- https://git.opendaylight.org/gerrit/#/q/status:open+topic:clustering,n,z
clustering related commits (colindixon,
16:24:26)
- general questions (devinavery, 16:28:40)
- Can you provide some pointers on the possible
query languages being developers for MD-SAL? (devinavery,
16:29:10)
- https://www.youtube.com/watch?v=UihFZpi8E-s
youtube video of xsql query stuff from Sharon (colindixon,
16:29:26)
- There is a NO-SQL type language being
developed. See notes from previous calls. (devinavery,
16:29:41)
- Also an effort ongoing with an intern to get
xpath working with MD-SAL - colindixion, devinavery regXboi, jan
medev are working on that (devinavery,
16:30:48)
- https://wiki.opendaylight.org/view/OpenDaylight_Controller:MD-SAL:XSQL
this the wiki page which walks through the XSQL (nosql-style) query
language and how you can play with it (colindixon,
16:32:05)
- Question about consolidating data models - is
anyone working on this? (devinavery,
16:32:45)
- Tony - the model colindixon mentioned is used
by the topology exporter. (devinavery,
16:34:02)
- Colindixon: in general there is a desire to
move towards having only one inventory/topology. Ask to Tony - do
you know if it is on the roadmap? (devinavery,
16:34:33)
- Tony there are some on going discussions.
Heavily depends on the community (devinavery,
16:34:55)
- Colin: topology stores hosts, inventory is the
root for flows. So you have to translate from topology to inventory
and back and forth because of the varying models. (devinavery,
16:36:01)
- topology does not not actually have hosts (at
least not at the moment) it stores the links betwee switches
(colindixon,
16:36:48)
- Tony: we would need someone to focus on a
migration strategy and so far there is no one actively working
it. (devinavery,
16:37:23)
- Jan: The open flow call discussed these models
and we need to kick off the conversation about the common models. We
need to start the discussions within open daylight and then move on
to IETF. (devinavery,
16:38:18)
- colindixon: suggestion we need some group of
people (really light way) who can review and track models going
into the code and can provide some comments on yangs to help
standardizing them (devinavery,
16:39:36)
- colindixon: that group could provide
suggestions when models are similar etc. (devinavery,
16:40:26)
- : devinavery: question: should the MD-SAL call
start the modeling discussions? (devinavery,
16:40:44)
- colindixon: we should at least open a bug to
merge the two models together. (devinavery,
16:41:18)
- ACTION: colindixon
will open a bug for a feature enhancement to merge the inventory and
topology models so we can at least track it (colindixon,
16:41:46)
- Next MD-SAL call - we can revisit this
discussion about a body of people to review the yang models as they
come in. Not proposing a a rigid review body... need to brain
storm (devinavery,
16:43:27)
- Question from Colin: If I have a DataObject, is
there an easy way to convert that to JSON or XLM without going
through restconf (devinavery,
16:44:05)
- Answer: you would need to replicate what
resting does under the hood, which is not exposed in a friendly API
right now. Question from Colin - should we open an
enhancement? (devinavery,
16:44:36)
- https://bugs.opendaylight.org/show_bug.cgi?id=1360
this is the bug to track (colindixon,
16:45:24)
- Enhancement 1360 is open and tracking this.
Colindixon is willing to start working if he can (devinavery,
16:45:27)
- ACTION: robert varga
to add some feedback on 1360 (colindixon,
16:48:25)
