Wide-column store based on ideas of BigTable and DynamoDB

Optimized for write access

A high performance open source SQL database for time series data

Port of SQLite to JavaScript

Cloud or off-cloud analytical database and query engine for structured and semi-structured streaming and batch data. Machine learning platform with built-in algorithms, data preparation capabilities, and model evaluation and management via SQL or Python.

Primary database model

Column oriented

Secondary database models
