Method Detail

HydraTask_initialize

public static void HydraTask_initialize()

Initialize the test and the regions

initialize

protected void initialize(String regionDescriptName)

HydraTask_putUnEvenlyTillThreshold

public static void HydraTask_putUnEvenlyTillThreshold()

Task to populate both the regions incrementally till it reaches the threshold

HydraTask_putExtraKeysWithSleep

public static void HydraTask_putExtraKeysWithSleep()

This task is done once the regions are populated till the eviction threshold is reached. In this task only one region is populated to trigger the eviction of both PRs.

HydraTask_logRegionSize

public static void HydraTask_logRegionSize()

HydraTask_printBucketAndDiskEntries

public static void HydraTask_printBucketAndDiskEntries()

HydraTask_verifyProportionateEviction

public static void HydraTask_verifyProportionateEviction()

Task to verify that even though the eviction is trigerred by one PR, both the PRs evict and they do in proportion to the bucket sizes

logRegionSize

protected void logRegionSize(com.gemstone.gemfire.internal.cache.PartitionedRegion aRegion)

populateSequentiallyAndIncrementally

protected void populateSequentiallyAndIncrementally()

populateSpecificBucketSpecificSize
