Concurrency Control[04]

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

Data Model[05]

A SenseiDB instance is a table of data that is organized into columns. Each column may fall into one of the supported types: string, int, long, short, float, double, char, date, text.

Indexes[06][07]

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

Isolation Levels[04]

The users are responsible for guaranteeing data isolation.

Joins[08]

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

Query Interface[09]

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

Storage Architecture[03]

Data is replicated in multiple disks to be robust against failures.

Stored Procedures

System Architecture[10]

The entire database is partitioned into a number of shards. Each shard is replicated across N nodes so that there might be more than one shards in a single node. Below is an example of a Sensei cluster.
