Purpose
Committer node may use a large memory if the amount of data written to the table is particularly large, OOM may occur
if the memory is too small. In this case, you need to increase the Committer heap memory, but you may not want to
increase the memory of Flink's TaskManager uniformly, which may lead to a waste of memory.
You can use fine-grained-resource-management of Flink to increase committer heap memory only:
cluster.fine-grained-resource-management.enabled: true. (This is default after Flink 1.18)sink.committer-cpu(for example 1.0) andsink.committer-memory(for example 300 MB, depends on yourTaskManager).Tests
