Memcached free keys
When a memcached key does not refer to the "_STA" or "_DYN"dataset of a system element, it takes a name of 8 characters followed by a 3 characters extension separated by a "_". Both the name and the extension are arbitrary even though It's advisable use conventional extensions:
| Extension | Description |
|---|---|
| _BUF | data buffers (FIFOs , circular, etc...) |
| _DAT | generic data structures |
| _EXT | extra data associated to a _STA or _DYN dataset |
