When creating a new key, it is essential to check that it is not already present in memcached.
When a memcached key does not refer to the "STA" or "DYN" fork of a system element, the format of its name is free and can be arbitrary defined, provided that it is not already used.
Even though the name format is arbitrary, it is a good practice to adopt conventional extensions (e.g. MYNEWVAL_DAT). In any case use the "_AUX" extension for a "free key".
To avoid the proliferation of extensions, try using the ones listed in the table below:
| Extension | Description |
|---|---|
| _BUF | Data buffers (FIFOs , circular buffers, etc...), not necessarily associated with a system element. |
| _INFO | Static metadata, not necessarily associated with a system element. |
| _DAT | Generic data structures, not necessarily associated with a system element. |
