Hi Beam Experts,I have a small query about `JdbcIO#readWithPartitions`
ContextJdbcIO#readWithPartitions seems to always default to 200 partitions
(DEFAULT_NUM_PARTITIONS). This is set by default when the object is
constructed here

Hi,
I had a small query about `JdbcIO`.
As per the documentation

`readWithPartitions` is supported for Long, DateTime

I believe you have to call withResults() on the JdbcIO transform in order
for this to work.

I added the @DefaultCoder as you told me and i removed the .withCoder from my

Hello all,
I hope this message finds you well. I am currently working with Apache Beam's
JdbcIO and need some guidance regarding setting a coder for the input data
without resorting to the deprecated withCoder method. I've been trying to
resolve this issue and would appreciate any insights
Hi,
We have been using JDBCIO for data ingestion from oracle; it works just
fine most of the days, but some days(usually the days when the DB is busy
because of high user activity) couple of our jobs which usually take ~15-20
mins get in stuck state within dataflow with stages showing indication
Hi,
I don’t think it’s possible “out-of-the-box” now but it could be a useful
add-on for JdbcIO connector (dead-letter pcollection) since, iirc, it was
already asked several times by users. For the moment, it’s only possible to
play with RetryStrategy/RetryConfiguration in case of failures
Hi all,
I am trying to figure out the right approach to handling failed records
when persisting to a database through the JdbcIO sink. We have created a
DoFn to do this task through a PreparedStatement and catch any exceptions
then send it through side output for further processing if required

Quick update.
After some testing, we have noticed that the splittable JdbcIO-poc works
well when the number of splits does not exceed the number of spark tasks.
In cases where the number of splits do exceed the task count, the pipeline
freezes after each worker has processed a single split each
plittable DoFn's, we decided to give it a try. We
essentially copied the source of JdbcIO into our project and changed
`ReadFn` into `SplittableJdbcIO` which acts as (more or less) a drop-in
replacement (see source below).
The DAG here is seemingly simpler with a single stage containing all steps
Hi,

Hi there,
We are struggling to get the JdbcIO-connector to read a large table on
spark.
In short - we wish to read a large table (several billion rows), transform
then write the transformed data to a new table.
We are aware that `JdbcIO.read()` does not parallelize. In order to solve
this, we

Thanks for details.
If I’m not mistaken, JdbcIO already supports both your suggestions for read and
write (at lest, in some way) [1][2].
Some examples from tests:
- write from PCollection [3],
- read to PCollection [4],
- write from PCollection with JavaBeanSchema [5]
Is it something
consider either:
- Moving this logic into JdbcIO and re-using it in JdbcSchemaIOProvider, or
- Adding a user-friendly interface to SchemaIOProvider implementations in
the Java SDK

Hello everyone,
I was wondering what is considered best-practice when writing SQL
statements for the JdbcIO connector?
Hand-writing the statements and subsequent preparedStatementSetter causes a
lot of bloat and is not very manageable.

I see. I wanted to get some feedback from community to see if calling proc
before running sql makes sense in JdbcIO. If that doesn't make sense then I
can close this JIRA.

Hi Community,
There is a stackoverflow question [1] asking how to call Oracle stored proc
in Beam via JdbcIO. I know very less on JdbcIO and Oracle, so just help ask

If there is no such support, I will create a JIRA

Hi Aleksandr,
I don't get your point about the connection: on your worker, who gonna
create the threads ? Basically, we will have a connection per thread
right now.
For the checkpoint, JdbcIO is basically a DoFn, it doesn't deal with a
CheckpointMark (if it's what you are talking about
with BQ service the exception will be thrown, but my job will be restored
from latest checkpoint. So I will not generate uuid for same message twice.
In case of jdbcio it is possible to get uuid for same mesage twice( in case
of multiple io it might be a problem).

"Jdbcio will create for each prepared statement new connection" - this is
not the case: the connection is created in @Setup and deleted in @Teardown.

Hello, we had similar problem. Current jdbcio will cause alot of connection
errors.
Typically you have more than one prepared statement. Jdbcio will create for
each prepared statement new connection(and close only in teardown) So it is
possible that connection will get timeot or in case in case
Agree especially using the current JdbcIO impl that creates connection in the
@Setup. Or it means that @Teardown is never called ?
