---------------------------------
Summary: Allow Ozone debug tools that need to read RocksDB to
automatically create a checkpoint
Key: HDDS-11775
URL: https://issues.apache.org/jira/browse/HDDS-11775
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ethan Rose
If a process like Ozone has a RocksDB instance open for write, then another
process like {{ozone debug}} cannot open the DB for reading. Many {{ozone
debug}} tools will not give consistent results on a DB undergoing writes
anyways. To fix this, we can have {{ozone debug}} operate on a RocksDB
checkpoint if the Ozone process is running. This avoids users having to
manually install RocksDB's ldb and make the checkpoint themselves. This could
be an optional flag like {{--checkpoint}} that instructs the command to create
a checkpoint from the RocksDB instance provided and read that instead.
