Uses of ResourceHolder in io.druid.query.groupby.epinephelinae

Method parameters in io.druid.query.groupby.epinephelinae with type arguments of type ResourceHolder

Modifier and Type

Method and Description

static Pair<Grouper<io.druid.query.groupby.epinephelinae.RowBasedGrouperHelper.RowBasedKey>,Accumulator<AggregateResult,Row>>

RowBasedGrouperHelper.createGrouperAccumulatorPair(GroupByQuery query, boolean isInputRaw, Map<String,ValueType> rawInputRowSignature, GroupByQueryConfig config, com.google.common.base.Supplier<ByteBuffer> bufferSupplier, com.google.common.base.Supplier<ResourceHolder<ByteBuffer>> combineBufferSupplier, int concurrencyHint, LimitedTemporaryStorage temporaryStorage, com.fasterxml.jackson.databind.ObjectMapper spillMapper, AggregatorFactory[] aggregatorFactories, com.google.common.util.concurrent.ListeningExecutorService grouperSorter, int priority, boolean hasQueryTimeout, long queryTimeoutAt, int mergeBufferSize) If isInputRaw is true, transformations such as timestamp truncation and extraction functions have not been applied to the input rows yet, for example, in a nested query, if an extraction function is being applied in the outer query to a field of the inner query.
