When a memcached key is associated with a system element (e.g. QUATB004), it takes the element name with two possible extensions: QUATB004_STA and QUATB004_DYN (for the the static and dynamic datasets).
When a memcached key is associated with a system element element but refers to data non belonging to its static or dynamic datasets (e.g. a waveform not included in the dynamic dataset), it takes the name of the element with the _BUF extension (e.g. DCTEL001_BUF is the acquisition buffer of the MRe Current Monitor)
When many different keys are associated with the system same element, they take different names but always end up with the _BUF extension (eg. ORBP*DAT_BUF, ORBP*AVG_BUF, ORBP*VAR_BUF are respectively: the last acquired, the average and the variance buffers of the MRp orbit).
