Redis has a module for working with bloom filters:

Redis also allows for pipelining of commands:

Specifically I am looking to check for the existence of a long list of items in a bloom filter. In the current implementation this requires me to issue N individual requests, one for each item in the checklist.
Looking for client code examples to pipeline a batch of BF.EXISTS calls in one network request.
No need to use pipeline. Instead, you can use BF.MEXISTS command to check multiple items:
BF.MEXISTS key item1 item2 item3
