Example 1 with TokenFactory

use of org.apache.cassandra.dht.Token.TokenFactory in project cassandra by apache.

the class NativeSSTableLoaderClient method init.

        tables.putAll(fetchTables(keyspace, session, partitioner, types));
        // We only need the TableMetadata for the views, so we only load that.
        tables.putAll(fetchViews(keyspace, session, partitioner, types));
