  14. def fetchColumns(columnSpecs: Seq[ColumnSpec]): Future[Map[ColumnSpec, Response]]

    Fetch method to simulate a random access interface for Chronon by distributing requests to relevant GroupBys.

    Fetch method to simulate a random access interface for Chronon by distributing requests to relevant GroupBys. This is a batch API which allows the caller to provide a sequence of ColumnSpec queries and receive a mapping of results.

    TODO: Metrics TODO: Collection identifier for metrics TODO: Consider removing prefix interface for this method TODO: Consider using simpler response type since mapping is redundant

    columnSpecs

    – batch of ColumnSpec queries

    returns

    Future map of query to GroupBy response
