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 8 characters names and conventional extensions (e.g. MYNEWVAL_DAT).
When creating a new "free key" name, it is essential to check that it is not already present in memcached.
| Extension | Description |
|---|---|
| _BUF | data buffers (FIFOs , circular, etc...) |
| _DAT | generic data structures |
| _AUX | auxiliary dataset (besides _STA and _DYN) associated to a system element |
