Example 1 with PartitionQueryRequest

use of com.google.spanner.v1.PartitionQueryRequest in project java-firestore by googleapis.

the class CollectionGroup method getPartitions.

/**
 * Partitions a query by returning partition cursors that can be used to run the query in
 * parallel. The returned partition cursors are split points that can be used as starting/end
 * points for the query results.
 *
 * @deprecated Please use {@link #getPartitions(long)} instead. All cursors will be loaded before
 *     any value will be provided to {@code observer}.
 * @param desiredPartitionCount The desired maximum number of partition points. The number must be
 *     strictly positive. The actual number of partitions returned may be fewer.
 * @param observer a stream observer that receives the result of the Partition request.
