------------------------------------------------------------------
Here's my concrete suggestion:
3 mutually exclusive ways of subscribing:
{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
2 non-mutually exclusive ways of specifying starting position, explicit
startingOffsets obviously take priority:
{noformat}
.option("startingOffsets", """{"topicFoo": {"0": 1234, "1", 4567}}""")
.option("startingTime", "earliest" | "latest" | long)
{noformat}
where long is a timestamp, work to be done on that later.
Note that even kafka 0.8 has a (really crappy based on log file modification
time) api for time so later pursuing timestamps startingTime doesn't
necessarily exclude it
