eXtremeDB vs ITTIA DB

eXtremeDB: Embedded in-memory and hybrid database for devices, real-time systems and time-series analytics. ITTIA DB: Embedded time-series and relational database for microcontrollers, RTOS and edge AI devices.

key differences

  • eXtremeDB is primarily a key-value database; ITTIA DB is time-series.
  • eXtremeDB is built for larger datasets (≤ 10 TB) than ITTIA DB (≤ 100 GB).
  • Horizontal scaling is native in eXtremeDB and none in ITTIA DB.
  • Only eXtremeDB has vector search, geospatial, columnar storage, compression, encryption at rest.
  • Only ITTIA DB has streaming ingest.
