Cody Koeninger commented on SPARK-17813:
----------------------------------------
So issues to be worked out here (assuming we're still ignoring compacted topics)
maxOffsetsPerTrigger - how are these maximums distributed among partitions?
What about skewed topics / partitions?
maxOffsetsPerTopicPartitionPerTrigger - (this isn't just hypothetical, e.g.
SPARK-17510) If we do this, how is this configuration communicated?
{noformat}
option("maxOffsetsPerTopicPartitionPerTrigger", """{"topicFoo":{"0":600},
"topicBar":{"0":300, "1": 600}}""")
{noformat}
{noformat}
option("maxOffsetsPerTopicPerTrigger", """{"topicFoo": 600, "topicBar": 300}""")

> At any given point in a streaming query execution, we process all available
> data. This maximizes throughput at the cost of latency. We should add
> something similar to the {{maxFilesPerTrigger}} option available for files.
