QUESTION
I'm building a websocket backend which would connect to a topic (with only one partition) and consume data from the earliest position and keep consuming for new data till the websocket connection is disconnected. At a single time more than one websocket connection can exist.
To ensure all data from begining is consumed, everytime a websocket connection is made, I'd make a new consumer group and subscribe to the topic
...ANSWER
Answered 2021-Nov-16 at 10:18Apparently this is a limitation in node-rdkafka
package. The default cunsumer/producer groups limit is 5. If you want to increase the limit set env variable UV_THREADPOOL_SIZE
in .env
file and the package would increase the limit of groups.

I have a typescript method that is trying to call a method, on()

...ANSWER
Answered 2020-Jun-28 at 16:10For people facing this problem in future: Please set UV_THREADPOOL_SIZE to a value more than 4 as an environment variable in your node application.
Explaination:
Each node process will have at least UV_THREADPOOL_SIZE + v8_thread_pool_size + 1 threads running.
the current default for both UV_THREADPOOL_SIZE and v8_thread_pool_size is 4.
QUESTION
I'm using node-rdkafka (https://github.com/Blizzard/node-rdkafka) to consume messages, the basic setup is working fine but it triggers the function every time I push something to the queue, irrespective of completion of previous method.
I want the next data unit to be triggered when the previous function is done.
here is my implementation
...ANSWER
Answered 2020-Jan-27 at 10:00You are calling consume()
(without any arguments) which returns messages as fast as possible.
If you want to control the consumption pace, you can use the other method consume(size)
, that returns size
Kafka records. For example consume(1)
will return the next Kafka record.
See the node-rdkafka Consumer docs.
