Constructor Detail

StressTestConcurrent.Task

public StressTestConcurrent.Task(IIndex ndx,
                         int keyLen,
                         int nops,
                         double insertRate,
                         IIndex groundTruth,
                         ReentrantLock lock)

Parameters:

ndx - The index under test.

groundTruth - Used for performing ground truth correctness tests when running against one or more data services with index partition split, move, and join enabled (optional). When specified this should be backed by a TemporaryStore or TemporaryRawStore. The caller is responsible for validating the index under test against the ground truth on completion of the test.

lock - Used to coordinate operations on the groundTruth store. May be null if the groundTruth store is null.

Method Detail

call

public Void call()
          throws Exception

Executes a random batch operation with keys presented in sorted order.

Note: Batch operations with sorted keys have twice the performance of the corresponding operation with unsorted keys due to improved locality of the lookups performed on the index.

Specified by:

call in interface Callable<Void>

Returns:

The commit time of the transaction.

Throws:

Exception
