Examples with KeyspaceParams org.apache.cassandra.schema.KeyspaceParams used on opensource projects

Example 1 with KeyspaceParams

use of org.apache.cassandra.schema.KeyspaceParams in project cassandra by apache.

the class KeyspaceAttributes method asAlteredKeyspaceParams.

public KeyspaceParams asAlteredKeyspaceParams(KeyspaceParams previous) {
    boolean durableWrites = getBoolean(Option.DURABLE_WRITES.toString(), previous.durableWrites);
    ReplicationParams replication = getReplicationStrategyClass() == null ? previous.replication : ReplicationParams.fromMap(getAllReplicationOptions());
    return new KeyspaceParams(durableWrites, replication);
}

Example 2 with KeyspaceParams

use of org.apache.cassandra.schema.KeyspaceParams in project cassandra by apache.

the class AlterKeyspaceStatement method validate.

public void validate(ClientState state) throws RequestValidationException {
    KeyspaceMetadata ksm = Schema.instance.getKeyspaceMetadata(name);
    if (ksm == null)
        throw new InvalidRequestException("Unknown keyspace " + name);

        // The strategy is validated through KSMetaData.validate() in announceKeyspaceUpdate below.
        // However, for backward compatibility with thrift, this doesn't validate unexpected options yet,
        // so doing proper validation here.
        KeyspaceParams params = attrs.asAlteredKeyspaceParams(ksm.params);
        params.validate(name);
        if (params.replication.klass.equals(LocalStrategy.class))
