Hi, @fengbaoli. Flink + Fluss support delta join is a combination of Flink's DeltaJoin operator and Fluss's prefixLookup to lookup data from Fluss. The introduction of Flink's DeltaJoin operator is based on the discussion in the FLIP which is still under discussion. The prefixLookup of Fluss has already been merged into the main branch and can be formally used after the release of v0.6. Therefore, the formal use of the delta join capability will depend on the progress of discussions and development of this FLIP
