Roman Leventov 84fe91ba0b Monomorphic processing of TopN queries with 1 and 2 aggregators (key part of #3798) (#3889) ... * Monomorphic processing: add HotLoopCallee, CalledFromHotLoop, RuntimeShapeInspector, SpecializationService. Specialize topN queries with 1 or 2 aggregators. Add Cursor.advanceUninterruptibly() and isDoneOrInterrupted() for exception-free query processing. * Use Execs.singleThreaded() * RuntimeShapeInspector to support nullable fields * Make CalledFromHotLoop annotation Inherited * Remove unnecessary conversion of array of ColumnSelectorPluses to list and back to array in CardinalityAggregatorFactory * Close InputStream in SpecializationService * Formatting * Test specialized PooledTopNScanners * Set flags in PooledTopNAlgorithm directly * Fix tests, dependent on CountAggragatorFactory toString() form * Fix * Revert CountAggregatorFactory changes * Implement inspectRuntimeShape() for LongWrappingDimensionSelector and FloatWrappingDimensionSelector * Remove duplicate RoaringBitmap dependency in the extendedset pom.xml * Fix * Treat ByteBuffers specially in StringRuntimeShape * Doc fix * Annotate BufferAggregator.init() with CalledFromHotLoop * Make triggerSpecializationIterationsThreshold an int * Remove SpecializationService.PerPrototypeClassState.of() * Add comments * Limit the amount of specializations that SpecializationService could make * Add default implementation for BufferAggregator.inspectRuntimeShape(), for compatibility with extensions * Use more efficient ConcurrentMap's idioms in SpecializationService		2017-03-17 14:44:36 -05:00
