1. abstract class Api extends Serializable

   

2. class ArrayRow extends Row

   

   Consumed by row aggregator after decoding.

   Consumed by row aggregator after decoding. Mutations follow the same schema as input for value indices. However there are two main differences. * ts and reversal columns are required for computation * Mutation ts takes on the role of ts. Since the schema is the same with the sole difference of the added columns, we add these columns on the tail of the Array and extract them accordingly. i.e. for mutations: reversal index = ArrayRow.length - (Constants.MutationAvroColumns.length - (index of reversal in Constants.MutationAvroColumns)

30. case class Mutation(schema: StructType = null, before: Array[Any] = null, after: Array[Any] = null) extends Product with Serializable

    

    Mutation is the general case of an Event Imagine a user impression/view stream - impressions/views are immutable events Imagine a stream of changes to a credit card transaction stream.

    MUTATION vs. EVENT

    Mutation is the general case of an Event Imagine a user impression/view stream - impressions/views are immutable events Imagine a stream of changes to a credit card transaction stream.

    • transactions can be "corrected"/updated & deleted, besides being "inserted"
    • This is one of the core difference between entity and event sources. Events are insert-only.
    • (The other difference is Entites are stored in the warehouse typically as snapshots of the table as of midnight) In case of an update - one must produce both before and after values In case of a delete - only before is populated & after is left as null In case of a insert - only after is populated & before is left as null

    TIME ASSUMPTIONS

    The schema needs to contain a ts(milliseconds as a java Long) For the entities case, mutation_ts when absent will use ts as a replacement

40. class TileCodec extends AnyRef

    

    TileCodec is a helper class that allows for the creation of pre-aggregated tiles of feature values.

    TileCodec is a helper class that allows for the creation of pre-aggregated tiles of feature values. These pre-aggregated tiles can be used in the serving layer to compute the final feature values along with batch pre-aggregates produced by GroupByUploads. The pre-aggregated tiles are serialized as Avro and indicate whether the tile is complete or not (partial aggregates)
