    • isSingleThreaded

      public boolean isSingleThreaded()

    • setSingleThreaded

      public void setSingleThreaded(boolean singleThreaded)

    • 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()

    • getMaxSpillFileCount

      public int getMaxSpillFileCount()

    • 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
