An asynchronous meta backend for OpenLDAP
The purpose of the talk is to describe the architecture, configuration specifics, advantages and restrictions of the new OpenLDAP backend module – back-asyncmeta. The back-asyncmeta is developed on the basis of the currently existing back-meta, with the major distinction that the responses to operations sent to the remote servers are received asynchronously, to avoid the front-end server being unresponsive while waiting for too many slow back-end servers. While asyncmeta shares a lot of code and features with the existing back-meta, the transformation to asynchronous operation lead to large code and architecture restructuring, which are described in the talk.
The structure of the talk is:
- Why is development of asyncmeta necessary
- Architecture of asyncmeta
- What is different in terms of behaviour and features as compared to back-meta
- Additional requirement to asyncmeta
- Example configuration, including new configuration options
