| """ |
| The top-level library for Heron's Python Streamlet API, which enables you to |
| write Heron [topologies](https://apache.github.io/incubator-heron/docs/concepts/topologies/) |
| using the Python Streamlet API. |
| |
| Heron topologies are acyclic graphs used to process streaming data. Topologies |
| have two major components: |
| [spouts](spout/spout.m.html#heron_py.spout.spout.Spout) pull data into the |
| topology and then [emit](spout/spout.m.html#heron_py.spout.spout.Spout.emit) |
| that data as tuples (lists in Python) to |
| [bolts](bolt/bolt.m.html#heron_py.bolt.bolt.Bolt) that process that data. |
