Subject Re: Starting up cassandra 0.7
Date Tue, 16 Nov 2010 19:58:20 GMT
This is embedded for testing cassandra 0.7 beta2.  using
EmbeddedCassandraService.

and manually adding schema programmatically using:
        for (KSMetaData table : DatabaseDescriptor.readTablesFromYaml()) {
            for (CFMetaData cfm : table.cfMetaData().values()) {
                CFMetaData.map(cfm);
            }
            DatabaseDescriptor.setTableDefinition(table,
                    DatabaseDescriptor.getDefsVersion());
        }

Is this the correct way to start up a test server, with the schema loaded?
