Getting Started

Worker Model

By default, the web service starts with one worker process. Each worker handles documents in a single-threaded mode that means that it can process only one request at a time. The number of workers is limited by available hardware resources.

Minimum System Requirements

The minimum acceptable hardware: 1 CPU and 2 GB RAM per worker.


The version A.B.C.D.E is composed of:

  • A.B for the Regula SDK version
  • C for the document database version
  • D for the service wrapper version
  • E for the patch number

For example, the 5.2.103350.140.p1 version should be interpreted as follows:

  • 5.2 is the Regula SDK version
  • 103350 is the current document database version
  • 140 is the web service wrapper version
  • p1 is the patch number (contains security or bug fixes)
