I tried to downgrade from Scylla 5.1 to 5.0. As there already are ME sstables written, I tried to start the scylla 5.1 nodes with “sstable_format: md”. But unfortunetaly I am getting an error when starting scylla back up:
scylla: [shard 0] init - Startup failed: std::runtime_error (Feature ‘ME_SSTABLE_FORMAT’ was previously enabled in the cluster but its support is disabled by this node. Set the corresponding configuration option to enable the support for the feature.)
Should this setting simply prevent scylla from writing me-sstables, but still be able to read them?
Is there any other way to downgrade back to 5.0?
