Please refer the structured streaming guide doc which is very clear of
representing when the query will have unbounded state.

Quoting the doc:
In other words, you will
You mean to say that Spark will store all the data in memory forever :)

Hi,
I would like to confirm checkpointing behavior, I have observed following
scenarios:
*1)* When I set checkpointLocation from streaming query like:
val query =
rateDF.writeStream.format("console").outputMode("append").trigger(Trigger.ProcessingTime("1
seconds")).*option("checkpointLocation",
Ah, sorry. I missed it. It works correctly. Thanks.

Did you do the step where you sync your GitHub and ASF account? After an
hour you should get an email and then you can.

BTW, should I be able to close PRs via GitHub UI right now or is there
another way to do it? Looks I'm not seeing the close button.

Agree, I'll ask on the INFRA ticket and follow up. That's a lot of extra noise.

Anyone can attend the v2 sync. You just need to let me know what email
address you'd like to have added. Sorry it is invite-only. That's a
limitation of the platform (hangouts), the Spark community welcomes anyone
that wants to participate.

Hmm, it also seems that github comments are being sync'ed to jira.
That's gonna get old very quickly, we should probably ask infra to
disable that (if we can't do it ourselves).

Update for committers: now that my user ID is synced, I can
successfully push to remote https://github.com/apache/spark directly.
Use that as the 'apache' remote (if you like; gitbox also works). I
confirmed the sync works both ways.
As a bonus you can directly close pull requests when needed
Per the thread last week, the Apache Spark repos have migrated from
https://git-wip-us.apache.org/repos/asf to
https://gitbox.apache.org/repos/asf
Non-committers:
This just means repointing any references to the old repository to the
new one. It won't affect you if you were already referencing
Hi Abhijeet,
You are using inner join with unbounded state which means every data in
stream ll match with other stream infinitely,
If you want the intended behaviour you should add time stamp conditions
or window operator in join condition

Hello,
I’m using watermark to join two streams as you can see below:
val order_wm = order_details.withWatermark("tstamp_trans", "20 seconds")
val invoice_wm = invoice_details.withWatermark("tstamp_trans", "20 seconds")
val join_df = order_wm
.join(invoice_wm, order_wm.col("s_order_id") ===
I think you are generally right, but there are so many different scenarios
that it might not always be the best option, consider for instance a "fast"
network in between a single data source and "Spark", lots of data, an
"expensive" (with low selectivity) expression as Wenchen suggested.
In such
Ah, yes, you are right. The DataSourceV2 APIs wouldn’t let an implementor mark
a DataSet as “bucketed”. Is there any documentation about the upcoming table
support for data source v2 or any way of getting invited to the DataSourceV2
community sync?
Thanks!
Ximo.
