env.enableCheckpointing(30);
Hi Leonard,
I am using flink 1.11.2 and using debezium-json to read CDC data generated
by debezium.
For each table, I convert the Kafka dynamic table to a retract stream and
finally that stream is converted to DataStream. Here's the sample
function
private DataStream getDataStream(String sql) {
1. I use the filesystem as the state backend, and the state should be in memory.
2. The mini-batch function is disabled.
3. Does mini-batch reduce memory usage? I found that the memory usage of the
overwindows grew fast and the JVM FunllGC was frequent. Tenured Gen occupies a
large amount of me
AFAIK, the ClusterClient should not be exposed through the public API.
Would you like to explain your use case and why you need to get the
web UI programmatically?
Best,
Yangze Guo

Hi, Ayush
Thanks for the detailed description.
Before analyze the issue, I have two questions that which Flink and Flink CDC
version are you using? Is Flink CDC used in SQL or DataStream ?
That’s helpful if you can post you Flink CDC connector parameters.
Best,
Leonard

Hi!
As the state grows the processing speed will slow down a bit. Which state
backend are you using? Is mini batch enabled[1]?
