Method Detail

getDefaultStrategy

public String getDefaultStrategy()

isSingleThreaded

public boolean isSingleThreaded()

setSingleThreaded

public void setSingleThreaded(boolean singleThreaded)

getMaxIntermediateRows

public int getMaxIntermediateRows()

setMaxIntermediateRows

public void setMaxIntermediateRows(int maxIntermediateRows)

getMaxResults

public int getMaxResults()

setMaxResults

public void setMaxResults(int maxResults)

getBufferGrouperMaxSize

public int getBufferGrouperMaxSize()

getBufferGrouperMaxLoadFactor

public float getBufferGrouperMaxLoadFactor()

getBufferGrouperInitialBuckets

public int getBufferGrouperInitialBuckets()

getActualMaxSelectorDictionarySize

public long getActualMaxSelectorDictionarySize(DruidProcessingConfig processingConfig)

getActualMaxMergingDictionarySize

public long getActualMaxMergingDictionarySize(long maxHeapSize,
                                              int numConcurrentQueries)

For unit tests. Production code should use getActualMaxMergingDictionarySize(long, int).

getActualMaxMergingDictionarySize

public long getActualMaxMergingDictionarySize(DruidProcessingConfig processingConfig)

getMaxOnDiskStorage

public HumanReadableBytes getMaxOnDiskStorage()

getDefaultOnDiskStorage

public HumanReadableBytes getDefaultOnDiskStorage()

Mirror maxOnDiskStorage if defaultOnDiskStorage's default is not overridden by cluster operator. This mirroring is done to maintain continuity in behavior between Druid versions. If an operator wants to use defaultOnDiskStorage, they have to explicitly override it.

Returns:

The working value for defaultOnDiskStorage

isForcePushDownLimit

public boolean isForcePushDownLimit()

isApplyLimitPushDownToSegment

public boolean isApplyLimitPushDownToSegment()

isForceHashAggregation

public boolean isForceHashAggregation()

getIntermediateCombineDegree

public int getIntermediateCombineDegree()

getNumParallelCombineThreads

public int getNumParallelCombineThreads()

isMergeThreadLocal

public boolean isMergeThreadLocal()

isVectorize

public boolean isVectorize()

isIntermediateResultAsMapCompat

public boolean isIntermediateResultAsMapCompat()

isForcePushDownNestedQuery

public boolean isForcePushDownNestedQuery()

isMultiValueUnnestingEnabled

public boolean isMultiValueUnnestingEnabled()

withOverrides

public GroupByQueryConfig withOverrides(GroupByQuery query)

toString

public String toString()

Overrides:

toString in class Object
