A stress test of concurrent writers on one or more named indices.

Parameters:

journal - The database.

timeout - The #of seconds before the test will terminate.

nresources - The #of named indices that will be used by the tasks.

minLocks - The minimum #of resources in which a writer will obtain a lock in [0:nresources].

maxLocks - The maximum #of resources in which a writer will obtain a lock in [minLocks:nresources].

ntrials - The #of transactions to execute.

keyLen - The length of the random unsigned byte[] keys used in the operations. The longer the keys the less likely it is that there will be a write-write conflict (that concurrent txs will write on the same key).

nops - The #of operations to be performed in each transaction.

failureRate - The percentage of Writers that will throw a SpuriousException rather than completing normally.

Throws:

InterruptedException

main

public static void main(String[] args)
                 throws Exception

Runs a single instance of the test as configured in the code.

Throws:

Exception

doComparisonTest

public com.bigdata.testutil.ExperimentDriver.Result doComparisonTest(Properties properties)
                                                              throws Exception

Setup and run a test.

Specified by:

doComparisonTest in interface com.bigdata.testutil.ExperimentDriver.IComparisonTest

Parameters:

properties - There are no "optional" properties - you must make sure that each property has a defined value.

Throws:

Exception
