Sabisu introduces Shika – a lightweight OPC historian and data persistence layer




Over the past few months we’ve been working really hard on a new product and today we’re excited to share it with you. It’s called Shika.

What is Shika?

Shika is a lightweight OPC historian and data persistence layer.

Shika is designed for:

  • Speed; rapid storage and retrieval of numeric data
  • Scale; storing large amounts of high frequency data
  • Flexibility; storing data from a wide range of sources

We created Shika for continuous storage of chronological manufacturing process data.

How does it work?

Shika is easy to implement, with a tag-based structure familiar to automation and manufacturing IT teams. Breakthrough in-memory storage and processing means tag value read/write acces at high speeds.
In real-world tests, Shika has recorded read/write speeds of ~1000x faster than SQL.

(We have benchmarks to verify this.)


How do I get started?

Shika is self-contained, ready to use and really easy to install. You can run it remotely as a server or embed it directly into your own application. Shika has no dependencies on 3rd party database systems, expensive hardware or specialist skills and training. We’ve even implemented it on a Raspberry Pi.
