Zeebe is designed for performance, applying the following design principles:

  • Batching of I/O operations
  • Linear read/write data access patterns
  • Compact, cache-optimized data structures
  • Lock-free algorithms and actor concurrency (green threads model)
  • Broker is garbage-free in the hot/data path

As a result, Zeebe is capable of very high throughput on a single node and scales horizontally (see this benchmarking blog post for more detail).
