> Right now you can only run a Streaming Query starting from either the earliest or latests offsets available at the moment the query is started.  Sometimes this is a lot of data.  It would be nice to be able to do the following:
>  - seek to user specified offsets for manually specified topicpartitions
> currently agreed on plan:
> 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.
