Blockstore
The validator blockstore rocksdb database can be inspected using the ldb
tool.
ldb
is part of the rocksdb
code base and is also available in the rocksdb-tools
package.

Upgrade
If a new software version introduces a new column family to the blockstore, that new (empty) column will be automatically created. This is the same logic that allows a validator to start fresh without the blockstore directory.
Downgrade
If a new column family has been introduced to the validator blockstore, a subsequent downgrade of the validator to a version that predates the new column family will cause the validator to fail while opening the blockstore during startup.
List column families:
ldb --db=<validator ledger path>/rocksdb/ list_column_families
Warning: Please seek guidance on discord before modifying the validator blockstore.
Drop a column family:
ldb --db=<validator ledger path>/rocksdb drop_column_family <column family name>
