intermediateComputeSizeBytesConfigured

public int intermediateComputeSizeBytesConfigured()

intermediateComputeSizeBytes

public int intermediateComputeSizeBytes()

computeMaxMemoryFromMaxHeapSize

public static long computeMaxMemoryFromMaxHeapSize()

poolCacheMaxCount

public int poolCacheMaxCount()

getNumThreadsConfigured

public int getNumThreadsConfigured()

Overrides:

getNumThreadsConfigured in class ExecutorServiceConfig

getNumMergeBuffers

public int getNumMergeBuffers()

getNumMergeBuffersConfigured

public int getNumMergeBuffersConfigured()

Returns the number of merge buffers _explicitly_ configured, or -1 if it is not explicitly configured, that is not a valid number of buffers. To get the configured value or the default (valid) number, use getNumMergeBuffers(). This method exists for ability to distinguish between the default value set when there is no explicit config, and an explicitly configured value.
