Does anyone know any good java implementations for distributed key-value store?
You're probably looking for Hazelcast here. Note that it does much more than just a distributed k/v, but it will get you where you need to go.

Real-time stream processing with Hazelcast and Pulsar
In order to process the data collected, we used theHazelcast Pulsar connector module to ingest data from Pulsar topics (note: you can use the same connector to write to Pulsar topics). Using Hazelcast allows us to compute various aggregation functions (sum, avg etc.) in real time on a specified window of stream items. The Pulsar connector uses the Pulsar client library, which has two different ways of reading messages from a Pulsar topic. These are Consumer API and Reader API, both use the builder pattern (for more informationclick here).
