Examples with AggregationMetadata org.apache.rya.indexing.pcj.fluo.app.query.AggregationMetadata used on opensource projects

Example 1 with AggregationMetadata

use of org.apache.rya.indexing.pcj.fluo.app.query.AggregationMetadata in project incubator-rya by apache.

the class AggregationObserver method parseObservation.

@Override
public Observation parseObservation(final TransactionBase tx, final Bytes row) {
    requireNonNull(tx);
    requireNonNull(row);
    // Make nodeId and fetch the Aggregation node's metadata.
    final String nodeId = BindingSetRow.makeFromShardedRow(Bytes.of(AGGREGATION_PREFIX), row).getNodeId();
    final AggregationMetadata metadata = queryDao.readAggregationMetadata(tx, nodeId);
    // Read the Visibility Binding Set from the value.
    final Bytes stateBytes = tx.get(row, FluoQueryColumns.AGGREGATION_BINDING_SET);
    final AggregationState state = STATE_SERDE.deserialize(stateBytes.toArray());
    final VisibilityBindingSet aggBindingSet = new VisibilityBindingSet(state.getBindingSet(), state.getVisibility());
    // Figure out which node needs to handle the new metadata.
    final String parentNodeId = metadata.getParentNodeId();
    return new Observation(nodeId, aggBindingSet, parentNodeId);
}
