Subject [jira] [Commented] (SPARK-17812) More granular control of starting offsets (assign)
Date Thu, 13 Oct 2016 21:01:20 GMT

    [ https://issues.apache.org/jira/browse/SPARK-17812?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15573166#comment-15573166
] 

Cody Koeninger commented on SPARK-17812:
----------------------------------------

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

> 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
