Elek, Marton commented on HDDS-1000:
------------------------------------
The earlier implementation for something like this is
hadoop/hadoop-ozone/tools/src/main/java/org/apache/hadoop/ozone/scm/cli/SQLCLI.java,
but I am almost sure that it doesn't work any more (it generated sql script
instead of yam)
And one related issue is HDDS-748. With this Jira it's possible to define the
encode/decode logic for rocksdb in separated class, so any tool and the server
side can share the logic (this is not yet adopted on the datanode side)
Just for the context: We also checked that
[https://calcite.apache.org/|https://calcite.apache.org/it] could be one option
to provide similar functionality as the SQLCLI (especially together with the
codecs) but I assume that this Jira can be implemented in a more simple way.
