Description

 

There is a bug when computing `FeaturesDelta` which cause us to generate snapshot on every commit.

 

[2022-06-08 13:07:43,010] INFO [BrokerMetadataSnapshotter id=0] Creating a new snapshot at offset 0... (kafka.server.metadata.BrokerMetadataSnapshotter:66)

[2022-06-08 13:07:43,222] INFO [BrokerMetadataSnapshotter id=0] Creating a new snapshot at offset 2... (kafka.server.metadata.BrokerMetadataSnapshotter:66)

[2022-06-08 13:07:44,228] INFO [BrokerMetadataSnapshotter id=0] Creating a new snapshot at offset 4... (kafka.server.metadata.BrokerMetadataSnapshotter:66)

 

Before a broker being unfenced, it won't starting publishing metadata, so it's meaningless to  generate a snapshot.
