IonDB is no longer under active development. It is replaced by EmbedDB that provides efficient time series, key-value, and relational data processing for Arduinos and embedded devices.
Currently in the Arduino world, there doesn't exist an associative array or map implementation that is both easy to use and performance competitive. There also is little support for disk based storage options that don't involve writing it yourself. IonDB is fast, functional, and offers disk based storage out of the box.
In general, IonDB supports:
- Storing arbitrary values associated to a key
- Duplicate key support
- Range and Equality queries
- Disk based persistent data storage
IonDB has a paper that was published at IEEE (CCECE) 2015, which can be found here.
