Xing Pan commented on HUDI-269:
-------------------------------
[~vbalaji] :
yeah, this is just a single test hudi app in my sandbox emr, so I'm pretty sure
only this one hudi spark job is writing to this bucket.
I just have one partition for this table.
and I've test it on two scenarios:
# nothing come from kafka at all.
# 10 records come in each 5 seconds.
and I didn't do any query on this table during delta sync, do you expect
request count decrease from query end?
I've set sync interval = 0 in some tests, so I think it've ran of several
iterations.

> In some scenario in our cluster, we may want delta streamer to slow down a
> bit.
> so it's nice to have a parameter to control the min sync interval of each
> sync in continuous mode.
> this param is default to 0, so this should not affect current logic.
> minor pr: [#921|https://github.com/apache/incubator-hudi/pull/921]
> the main reason we want to slow it down is that aws s3 is charged by s3
> get/put/list requests. we don't want to pay for too many requests for a
> really slow change table.
