liangyepianzhou opened a new pull request #12449:
URL: https://github.com/apache/pulsar/pull/12449
Master Issue: #<xyz>
### Motivation
Redundant information does not need to be stored for a long time. The
messages that have been aborted in a transaction and the Txn Marks that have
been read are all redundant information
### Modifications
Modified the offload method in ledgerOffload interface, and added an
OffloadFilter type parameter.
OffloadFilter is a newly added interface, responsible for judging from the
perspective of transaction,
whether the ledger can be uninstalled, and the entry needs to be offloaded
and so on. The main implementation is OffloadFilterImp and OffloadFilterDisabled
