MemtableParams	Memtable types and options are specified with these parameters.
MigrationCoordinator	Migration coordinator is responsible for tracking schema versions on various nodes and, if needed, synchronize the schema.
OfflineSchemaUpdateHandler	Update handler which works only in memory.
PartitionDenylist	PartitionDenylist uses the system_distributed.partition_denylist table to maintain a list of denylisted partition keys for each keyspace/table.
ReplicationParams
Schema	Manages shared schema, keyspace instances and table metadata refs.
SchemaChangeNotifier	Registers schema change listeners and sends the notifications.
SchemaConstants	When adding new String keyspace names here, double check if it needs to be added to PartitionDenylist.canDenylistKeyspace
SchemaEvent
SchemaKeyspace	system_schema.* tables and methods for manipulating them.
SchemaKeyspaceTables
SchemaMutationsSerializer
SchemaPullVerbHandler	Sends it's current schema state in form of mutations in response to the remote node's request.
