Introduction

A global plugin that steps in during kdbGet() process to filter the results in a way, so that no other keys than the requested one or descendants of it are returned. During kdbSet() the filtered keys are added back to the output, so that they don't get lost during the storage process. In other words, the plugin caches filtered keys to simplify the use of the API.

Usage

There is not much to do to use the plugin. Just mount is as global plugin and you are done:

# Backup-and-Restore: system/elektra/globalplugins
kdb global-mount cachefilter

To remove the plugin just use kdb global-umount:

kdb global-umount cachefilter
