+date: 2023-04-18 15:00:00 +0000
+version: fluo-2.0.0
+---
+
+Apache Fluo is a distributed processing system that lets users make incremental
+updates to large data sets.  With Apache Fluo, users can set up workflows that
+execute cross node transactions when data changes. These workflows enable users
+to continuously join new data into large existing data sets without
+reprocessing all data.  Apache Fluo is built on [Apache Accumulo].

+Apache Fluo follows [semver](http://semver.org/) for its API . The API consists
+of everything under the `org.apache.fluo.api` package. Code outside of this
+package can change at any time. If your project is using Fluo code that falls
+outside of the API, then consider [initiating a discussion](/getinvolved/)
+about adding it to the API.
