StreamingGlobalLimitExec

case class StreamingGlobalLimitExec(streamLimit: Long, child: SparkPlan, stateInfo: Option[StatefulOperatorStateInfo] = None, outputMode: Option[OutputMode] = None) extends SparkPlan with UnaryExecNode with StateStoreWriter with Product with Serializable

A physical operator for executing a streaming limit, which makes sure no more than streamLimit rows are returned. This physical operator is only meant for logical limit operations that will get a input stream of rows that are effectively appends. For example, - limit on any query in append mode - limit before the aggregation in a streaming aggregation query complete mode

  113. def produceOutputWatermark(inputWatermarkMs: Long): Option[Long]

    Produce the output watermark for given input watermark (ms).

    Produce the output watermark for given input watermark (ms).

    In most cases, this is same as the criteria of state eviction, as most stateful operators produce the output from two different kinds:

    1. without buffering 2. with buffering (state)

    The state eviction happens when event time exceeds a "certain threshold of timestamp", which denotes a lower bound of event time values for output (output watermark).

    The default implementation provides the input watermark as it is. Most built-in operators will evict based on min input watermark and ensure it will be minimum of the event time value for the output so far (including output from eviction). Operators which behave differently (e.g. different criteria on eviction) must override this method.

    Note that the default behavior wil advance the watermark aggressively to simplify the logic, but it does not break the semantic of output watermark, which is following:

    An operator guarantees that it will not emit record with an event timestamp lower than its output watermark.

    For example, for 5 minutes time window aggregation, the advancement of watermark can happen "before" the window has been evicted and produced as output. Say, suppose there's an window in state: [0, 5) and input watermark = 3. Although there is no output for this operator, this operator will produce an output watermark as 3. It's still respecting the guarantee, as the operator will produce the window [0, 5) only when the output watermark is equal or greater than 5, and the downstream operator will process the input data, "and then" advance the watermark. Hence this window is considered as "non-late" record.

    Specifies the data distribution requirements of all the children for this operator.

    Specifies the data distribution requirements of all the children for this operator. By default it's UnspecifiedDistribution for each child, which means each child can have any distribution.

    If an operator overwrites this method, and specifies distribution requirements(excluding UnspecifiedDistribution and BroadcastDistribution) for more than one child, Spark guarantees that the outputs of these children will have same number of partitions, so that the operator can safely zip partitions of these children's result RDDs. Some operators can leverage this guarantee to satisfy some interesting requirement, e.g., non-broadcast joins can specify HashClusteredDistribution(a,b) for its left child, and specify HashClusteredDistribution(c,d) for its right child, then it's guaranteed that left and right child are co-partitioned by a,b/c,d, which means tuples of same value are in the partitions of same index, e.g., (a=1,b=2) and (c=1,d=2) are both in the second partition of left and right child.
