Field Detail

maxConcurrentNodes

public int maxConcurrentNodes

Maximum number of concurrent requests to server nodes at any point in time. If there are 16 nodes in the cluster and maxConcurrentNodes is 8, then queries will be made to 8 nodes in parallel. When a query completes, a new query will be issued until all 16 nodes have been queried. Default (0) is to issue requests to all server nodes in parallel.

recordQueueSize

public int recordQueueSize

Number of records to place in queue before blocking. Records received from multiple server nodes will be placed in a queue. A separate thread consumes these records in parallel. If the queue is full, the producer threads will block until records are consumed.
