Cody Koeninger commented on SPARK-17812:
----------------------------------------
So I think this is what we're agreed on:
Mutually exclusive subscription options (only assign is new to this ticket)
{noformat}
.option("subscribe","topicFoo,topicBar")
.option("subscribePattern","topic.*")
.option("assign","""{"topicfoo": [0, 1],"topicbar": [0, 1]}""")
{noformat}
where assign can only be specified that way, no inline offsets
Single starting position option with three mutually exclusive types of value
{noformat}
.option("startingOffsets", "earliest" | "latest" | """{"topicFoo": {"0": 1234,
"1": -2}, "topicBar":{"0": -1}}""")
{noformat}
startingOffsets with json fails if any topicpartition in the assignments
doesn't have an offset.
Sound right?
I'll go ahead and start on it. I'm assuming I should try to reuse some of the
existing catalyst Jackson stuff and keep in mind a format that's potentially
usable by the checkpoints as well?
I don't think earliest / latest is too unclear as long as there's a way to get
to the other knobs that auto.offset.reset (should have) provided. Punting the
tunability of new partitions to another ticket sounds good.
