Draft / Open PRs Discussed in Meeting

PR	Discussion Summary	Status
sonic-sairedis #1897 – Improve smartswitch memory scaling	Conditionally caches high-volume DASH objects; 30–40% memory reduction observed on SONiC VS virtual test bed. Focus is memory improvement (not speed). Partial caching applied to select DASH objects. Before-and-after results to be added. Contributor: N. Hegde (new SONiC team member), context from Prabhat	Draft
sonic-SONiC #2336 – HA bulk sync failure handling	Open PR by Changrong defining bulk sync failure rollback to standalone mode. Still under construction	Open
sonic-swss-common #1188 – Expose batched ZmqProducerStateTable APIs	Enhances ZMQ producer state table APIs to enable batching for multiple entries per table, reducing end-to-end programming time by avoiding per-entry updates	Open

 

Additional Meeting Discussions

gNMI Client Placement (continued): The group noted ongoing collaboration between Michael and Mircea to land the gNMI client in sonic-management Docker. No new resolution this week; teams continuing async coordination.

 

Memorial Day Scheduling: Kristina checked in on upcoming meeting availability due to potential OOFs during Memorial Day week.
