When creating a new key, it is essential to check that it is not already present in memcached. |
When a memcached key does not directly refer to the "_STA" or "_DYN"dataset of a system element but – for example – to derived quantities, it takes a name of 8 characters followed by a 3 characters 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 advisable to always use UPPERCASE and append an extension separated by a "_" . Both the name and the extension are arbitrary even though (e.g. MY-ARBITRARY-NAME_DAT). In any case, do not use the "_AUX" extension for a "free key".
To avoid the proliferation of extensions, try using the ones listed in the table belowIt's advisable use conventional extensions:
| Extension | Description | |||
|---|---|---|---|---|
| _BUF BUF, _JBUF* | Data data buffers (FIFOs , circular buffers, etc...), not necessarily associated with a system element. | |||
| _ | DATgeneric data structures | _EXT | extra data associated to a _STA or _DYN datasetINFO, _JINFO* | Static metadata, not necessarily associated with a system element. |
| _DAT, _JDAT* | Generic data structures, not necessarily associated with a system element. |
(*) "J" prefix indicates that the key content is a Json document.
