SawtoothMutationAggregator

class SawtoothMutationAggregator extends SawtoothAggregator

Mutations processing starts with an end of the day snapshot FinalBatchIR. On top of this FinalBatchIR mutations are processed.

update/merge/finalize are related to snapshot data. As such they follow the snapshot Schema and aggregators. However mutations come into play later in the group by and a finalized version of the snapshot data is created to be processed with the mutations rows. Since the dataframe inputs are aligned between mutations and snapshot (input) no additional schema is needed.

    Given aggregations FinalBatchIRs at the end of the Snapshot (batchEndTs) and mutation and query times, determine the values at the query times for the aggregations.

    Given aggregations FinalBatchIRs at the end of the Snapshot (batchEndTs) and mutation and query times, determine the values at the query times for the aggregations. This is pretty much a mix of online with extra work for multiple queries ts support.
