Wally (formerly Wallaroo) is a fast, distributed stream-processing framework written in Pony that handles distributed computing plumbing so developers can focus on business logic. It provides high-performance, low-latency real-time data processing with managed in-memory state and live scaling.

Use cases

• process real-time data streams
• build distributed stream processing pipelines
• run stateful event processing with low latency
• scale a live data processing application without downtime
• react to incoming data in real time
• deploy stream processing on-prem or in the cloud

When to choose

• you need high-performance, low-latency stream processing with managed in-memory state
• you want to write stream processing apps in Pony or Python without managing distributed infrastructure
• you need live, elastic scaling of running data pipelines

When to avoid

• your team has no experience with the Pony language, which is the primary API
• you need a mainstream ecosystem with large community support like Kafka Streams or Flink
• the project has seen no releases since 2021 and you need actively maintained software
