SQWareProduction:cassandra
Presentation
Usage
It's the module locally operating of cassandra.
It is entirely written in ksh and sql.
It allows to manage the operation for cassandra.
Example uses of the tool:
- Backup
- Recovery
- Compute statistics
- Indicators collection to store in referential database SQWareRepository
- Rotate logs
- ....
This module is deployed locally on the machine hosting the authorities to manage,
in order to avoid any points of weakness related to an NFS mount or whatever.
The deployment is done through a simple command SQWareCentral module using inventory located in SQWareRepository !
