codelipenghui opened a new pull request #11389:
URL: https://github.com/apache/pulsar/pull/11389
### Motivation
Currently, the read ReadHandle only invalidates when removing the ledger
from the ManagedLedger.
If the ManagedLedger has many ledgers(the topic might retain infinite data),
we will get oom
on the direct memory since we are using 1MB read cache by default for the
offloaded data ReadHandle.
If all the cursors are consumed data, the ReadHandle can be closed safely.
And if a cursor reset
to an earlier position to consume the historical data, the ReadHandle will
be reopened again.
### Verifying this change
New tests were added to ensure the ReadHandle had been invalidated property.
