Resolution: Duplicate
> Fix downgrade handler for 0.14.0

> Since the log block version (due to delete block change) has been upgraded in
> 0.14.0, the delete blocks can not be read in 0.13.0 or earlier.
> Similarly the addition of record level index field in metadata table leads to
> column drop error on downgrade. The Jira aims to fix the downgrade handler to
> trigger compaction and delete metadata table if user wishes to downgrade from
> version six (0.14.0) to version 5 (0.13.0).
