InfluxDB IOx (short for Iron Oxide, pronounced InfluxDB "eye-ox") is the future
core of InfluxDB, an open source time series database. The name is in homage to
Rust, the language this project is written in. It is built using Apache Arrow
and DataFusion among other things. InfluxDB IOx aims to be:

- The future core of InfluxDB; supporting industry standard SQL, InfluxQL, and
Flux
- An in-memory columnar store using object storage for persistence
- A fast analytic database for structured and semi-structured events (like logs
and tracing data)
- A system for defining replication (synchronous, asynchronous, push and pull)
and partitioning rules for InfluxDB time series data and tabular analytics
data
- A system supporting real-time subscriptions
- A processor that can transform and do arbitrary computation on time series
and event data as it arrives
- An analytic database built for data science, supporting Apache Arrow Flight
for fast data transfer

Persistence is through Parquet files in object storage. It is a design goal to
support integration with other big data systems through object storage and
Parquet specifically.
