IsAggOptimized returns whether aggFn has an optimized implementation.

NewAggregateFuncsAlloc returns a new AggregateFuncsAlloc.

ProcessAggregations processes all aggregate functions specified in aggregations.

HashAggKind indicates the hash strategy of executing an aggregate function in a grouping context.

OrderedAggKind indicates the ordered strategy of executing an aggregate function in a grouping context.

WindowAggKind indicates that an aggregate function is being executed as a window function.

AggregateFuncsAlloc is a utility struct that pools allocations of multiple aggregate functions simultaneously (i.e.

NewAggregatorArgs encompasses all arguments necessary to instantiate either of the aggregators.

NewHashAggregatorArgs encompasses all mandatory arguments necessary to instantiate the hash aggregator.

AggregateFunc is an aggregate function that performs computation on a batch when Compute(batch) is called and writes the output to the Vec passed in in SetOutput.

AggKind represents the context in which an aggregate function is executed - in a grouping or a window context.
