QueryStrategy

trait QueryStrategy[-Q, -L, X] extends Serializable

Query support for summingbird beyond Key-Value Q represents the query object L represents the logical input keys from your data X represents the expansion of logical keys (can't co variant because Set is not)

Abstract Value Members

  1. abstract def index(key: L): Set[X]

    Used in your summingbird job to flatmap your keys, increment all these X with the value

  2. abstract def query(q: Q): Set[X]

    Used by the client reads, read all these X and sum the result
