How to migrate data from the backend storage (cassandra) #3498
-
Currently we use Janusgraph+Cassandra. Now we are going to migrate to the ScyllaDB. Does it mean that we broke some data during the migration? Do we need to migrate any other keyspace? |

Most probably you either didn't migrate data correctly or there are some problems with your cluster. Try to use Repair on ScyllaDB nodes and see if that helps. ScyllaDB also has docs about migration: https://docs.scylladb.com/stable/using-scylla/migrate-scylla.html |
