Message: Missing responseHandler for MapClearExpiredOperation

[Joan Balagueró]

Hello,

I have a 3-node cluster with just one IMap that contains few data. When I shutdown a node this message appears:

2023-12-15 09:28:09     [10.1.0.7]:9975 [ventusproxyCluster] [4.2.6] Repartitioning cluster data. Migration tasks count: 467

I suppose this is just a warning noticing me that data migration from this node to other nodes has started, but I would like to understand what this message exactly means, mainly when it's talking about "MapClearExpiredOperation".

Thanks a lot,

Joan.
