The return type of ConsumerStream.destroy is ConsumerStream (see type details with links at the bottom of this answer). You can refactor your method by prefixing the invocation of stream.destroy with the void operator:

Waiting for every to connect to a topic with new consumer group in kafka (node-rdkafka)

Asked 2021-Nov-16 at 10:18

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

Apparently 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(), that takes in a callback method. I'd like to have myConnect() wait until the callback method is executed. I assume this is a promise, but I'm not sure how to write this method so it waits until the callback is called.

For 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.

How to read message one by one in node-rdkafka

Asked 2020-Jan-28 at 01:40

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 10:00

You 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.
