Hi Community ,
Could anyone let me know if Flink is used in US healthcare tech space ?
Thanks,

Hi All,
I have recently been exploring MIDAS: an algorithm for Streaming Anomaly
Detection. A production level parallel and distributed implementation of
MIDAS should be quite useful to the industry. I feel that Flink is very
well-suited for the same as MIDAS deals with streaming data. If anyone i
Hello,
I'm having a bit of trouble understanding the memory configuration on
flink.
I'm using flink10.0.0 to read some datasets of edges and extract features.
I run this on a cluster consisting of 4 nodes , with 32cores and 252GB Ram
each, and hopefully I could expand this as long as I can add ext
With an AscendingTimestampExtractor, watermarks are not created for every
event, and as your job starts up, some events will be processed before the
first watermark is generated.
The impossible value you see is an initial value that's in place until the
first real watermark is available. On the ot

Hi Ori,
Here are some suggestions from my side.
- Probably the most straightforward way is to try increasing the timeout
to see if that helps. You can leverage the configuration option
`heartbeat.timeout`[1]. The default is 50s.
- It might be helpful to share your configuration setups
Hi Dimitris,
Regarding your questions.
a) For standalone clusters, the recommended way is to use `.flink.size`
rather than `.process.size`. `.process.size` includes JVM metaspace and
overhead in addition to `.flink.size`, which usually do not really matter
for standalone clusters.
b) In case of di
Hi Aissa,
Flink CEP is an api that processes multi-event matching with a pattern,
like (START MIDDLE+ END).
If you can calculate the "sensor_status" by one record, I think Flink
DataStream API / Table & SQL API
could satisfy your requirement already.

Hi kevin,
If you mean to add annotations for Flink native K8s session pods, you could
use "kubernetes.jobmanager.annotations"
and "kubernetes.taskmanager.annotations"[1]. However, they are only
supported from release-1.11. Maybe you could
wait for a little bit more time, 1.11 will be released soon
