-------------------------------------
[~kabhwan]
we applied *metadata.max.age.ms* on direct Kafka consumer config not through
Spark config
> Complete Metadata requests on each micro batch causing Kafka issues

> Key: SPARK-49442
> URL: https://issues.apache.org/jira/browse/SPARK-49442
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 3.3.2
> Reporter: vipin Kumar
> Priority: Major
> Labels: Kafka, spark-streaming-kafka
>
> We have noticed that spark does complete metadata requests on each micro
> batch and this is causing high metadata requests on small micro batch
> intervals .
>
> For example Kafka with 1900 partitions and 10 sec micro batch we are seeing
> order of
> ~{*}360K{*} metadata requests / sec
> Same with job with 60 sec micro batch we are observing *~60K* meta data
> requests.
>
> Metadata requests are controlled by *metadata.max.age.ms* but these config
> have no effect on spark consumers by default its 5 mins still we are seeing
> these huge requests.
