Hi Boris
For the configure you gave, you can try to reduce the parallelism of the
operator which contains states.

Thanks Tison for looking into it - what I tried to say is that Flink keeps
the files locked (hence, the space is still occupied) - this is visible
during a lsof command

For exactly-once mode before flink-1.5, it needs the temp dir for spilling the
blocking buffers during checkpoint.
The temp dir is configured via `io.tmp.dirs` and the default value is
`java.io.tmpdir`. In your case, your temp dir prefix with `/tmp/` has some
problems (might be deleted), and yo
Hi Mans,
AFAIK, we have no switch to disable general system metrics which are useful for
monitoring status and performance tuning. Only some advanced system metrics
could be confgiured to enable or not, and the default config is always
disabled, so you do not need toconcern them.
Maybe you cou

Maintaining only one Python API is helpful for users and contributors.

Hi Dan,
Said "The files are removed after a restart of the process", it sounds Flink
cleaned up blobs properly. From your description I don't understand clearly
in which case/situation you expected Flink deleted blobs but it doesn't.
Could you describe the difference between 1.4.2 and 1.7.2/1.8.0

Env.ssh.opts is the literal argument string to ssh as you would enter it on the
command line. Take a look at TMSlaves() in config.sh to see exactly how it’s
being used.

We will soon complete all the Python API functional development of the 1.9
release, the development of UDFs will be carried out. After the support of
UDFs is completed, it will be very natural to support Datastream API.

Hi,
Yes, multiple instances of the same De/SerializationSchema can be executed
in the same JVM.
Regarding 2. I'm not 100%, but would suspect that one
De/SerializationSchema instance handles multiple partitions.
Gordon (in CC) should know this for sure.

Hi Vinod,
Sorry for the late reply.
Your approach looks good to me.
A few things to note:
* It is not possible to set different idle state retention timers for
different parts of a query. All operators that support idle state retention
use the same configuration.
* The inner query with the SESSIO

Hi Team,
I'm struggling for a while with a strange issue: the local blob store files
are not actually deleted from the job manager/task manager in versions
1.7.2 and 1.8.0 : lsof commands shows them like this:

Hi all!
I would suggest to deprecating the existing python APIs for DataSet and

Background is that there is a new Python API under development.
The new Python API is initially against the Table API. Flink 1.9 will
