ClueCon Weekly with Viktor Litvinov: Kamailio's KDMQ - Performance, Clustering, and Beyond SIP

Do we need a database at all? Can we just share data directly from one Kamailio to another?"

This week on ClueCon Weekly, host Luca is joined by Viktor Litvinov — lead developer at Net2Phone and open-source contributor — for a deep dive into Kamailio's Distributed Message Queue (KDMQ) module and the improvements he's been working on.

Viktor walks through why KDMQ exists in the first place: real-time data replication without external database dependencies. From there, the conversation covers what's already been improved and what still needs doing.

What's covered:

• Moving beyond SIP as a transport for KDMQ messages

• Stateless message sending for performance gains

• New RPC commands for cluster management

• The KDMQ peer ID, for isolating replication across sites or deployments

• A last-write-wins approach to conflict resolution
