KIP-99 — Add Global Tables to Kafka Streams

Accepted Streams

Adds GlobalKTable to Kafka Streams, a fully-replicated, read-only table populated by a single stream thread from a compacted topic and joinable with any KStream without co-partitioning. Joining multiple dimension tables with a fact stream required repartitioning the fact stream for each join, incurring compounding network, disk, and latency costs.
