Zeebe Static Partitions Configuration
Raw
partition.md

Configuration Parameters

Required parameters on every broker in a Zeebe cluster (single topic). Only nodeId has to be unique per broker, other values have to be the same.

nodes = 5       (broker processes)
partitions = 6  (unrestricted)
replication = 3 (constraint <= nodes)
nodeId = x      (constraint unique between 0 and nodes (exclusive))

Partition Layout

With the given config values we can determine which node is responsible for which partition. Also if the partition does not exist locally the L (Leader) node will boostrap it.
