Duong commented on HDDS-9528:
-----------------------------
We should use ReferenceQueue to watch objects being GCed.
Example:

> Managed objects override finalize()

> URL: https://issues.apache.org/jira/browse/HDDS-9528
> Project: Apache Ozone
> Issue Type: Improvement
> Components: db
> Reporter: Tsz-wo Sze
> Priority: Major
>
> HDDS-9294 avoided creating Managed objects per get request. However, we
> still have
> - a ManagedReadOptions per db iterator.
> - a ManagedWriteBatch per RDBBatchOperation
> - snapshot related code using may Managed objects.
> Managed objects should not override finalize().
