Concurrency Control

Not Supported

SenseiDB partitions its data within the system to improve processing speed, but it only accepts a single data stream at a time.


Hash Table

SenseiDB applies an indexing manager called Zoie, which is a real-time search and indexing system supporting forward-rolling indexing.


Not Supported

Joins are not supported in SenseiDB since it is not a strictly relational database.

Query Interface

Custom API

Browsing Query Language (BQL) is supported by SenseiDB, which has the similar syntax to SQL.

Data Model
