Counters are implemented directly in Redis and therefore do no
behave like any other values set via redis.set
since they are
not serialized R objects. This is also why they have to be reset
using redis.zero
and cannot be set using
redis.set
.
Note that redis.dec
with N0=TRUE
is currently
implemented such that the counter is first decremented and only if it
leads to a negative value it is reset to zero.
integer, resulting counter value
