Max number of ingestion threads with Ingest Node?

Will it be better to increase the queue size to some 1500, so that the threads will be queued instead of elasticsearch sending 429 response?.

No, I wouldn't do that, it just increases memory usage and doesn't buy you anything as Filebeat just retries failed logs before continuing with next logs.
