| # flink-storm |
| |
| `flink-storm` is compatibility layer for Apache Storm and allows to embed Spouts or Bolts unmodified within a regular Flink streaming program (`SpoutWrapper` and `BoltWrapper`). |
| Additionally, a whole Storm topology can be submitted to Flink (see `FlinkLocalCluster`, and `FlinkSubmitter`). |
| Only a few minor changes to the original submitting code are required. |
| The code that builds the topology itself, can be reused unmodified. See `flink-storm-examples` for a simple word-count example. |
| |
| **Please note**: Do not add `storm-core` as a dependency. It is already included via `flink-storm`. |
| |
| The following Storm features are not (yet/fully) supported by the compatibility layer right now: |
| * no fault-tolerance guarantees (ie, calls to `ack()`/`fail()` and anchoring is ignored) |
| * for whole Storm topologies the following is not supported by Flink: |
| * direct emit connection pattern |
| * activating/deactivating and rebalancing of topologies |
| * task hooks |
| * metrics |
