The persister would then just need 1 of those while it worked during startup and then it would go away when done, unlike this. You could also then separately test the codec class (current parent) and the processor/callback fully that way rather than e.g creating a test subclass to test the parent bits, and not really _directly_ testing this class at all [it seems so far]. The large and regular persister could still use the same processor and then just toggle a flag to indicate which behaviour to give. ########## artemis-core-client/src/main/java/org/apache/activemq/artemis/core/protocol/core/CoreRemotingConnection.java: ########## @@ -81,6 +81,11 @@ default boolean isBeforeProducerMetricsChanged() { return version < PacketImpl.ARTEMIS_2_28_0_VERSION; } + default boolean isBeforeAMQPMapCodecChanged() { Review Comment: 'isBeforeAMQPMapCodecChanged' means barely anything to me now even with the context of the PR, its going to be incomprehensible the next time almost anyone sees it in future.

Its already the case that this system here isnt even used in the tracking the size and counts relating to the map(possibly plural at some point) that is encoded, or the large message boolean that is separate, so its already necessary to inspect multiple places to figure our what is going on (which doesnt tell you the size of any given thing, just the group of them) instead of just reading a comment on a constant. ########## artemis-protocols/artemis-amqp-protocol/src/main/java/org/apache/activemq/artemis/protocol/amqp/broker/AMQPMessageMapCodec.java: ########## @@ -0,0 +1,204 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
