filter(queryStream: DStream[(String, RunningQueryData)], bulletRecordStream: DStream[BulletRecord[_ <: Serializable]], broadcastedConfig: Broadcast[BulletSparkConfig]): DStream[(String, BulletData)]
Filter and apply partial aggregations for each query in the stream using the BulletRecord stream .
Filter and apply partial aggregations for each query in the stream using the BulletRecord stream .
This method takes the query stream and BulletRecord stream, and outputs com.yahoo.bullet.spark.data.BulletData stream (They can be com.yahoo.bullet.spark.data.BulletErrorData or com.yahoo.bullet.spark.data.FilterResultData)) to the JoinStreaming phase. In this method, the query stream is collected and broadcast to all executors. In each partition, queries consume the Bullet records and generate the output com.yahoo.bullet.spark.data.BulletData accordingly.
- queryStream
The input query stream.
- bulletRecordStream
The input BulletRecord stream.
- broadcastedConfig
The broadcasted com.yahoo.bullet.spark.utils.BulletSparkConfig configuration that has been validated.
- returns
A com.yahoo.bullet.spark.data.BulletData stream which contains the intermediate results for queries.
