Module store_incr 

store-incr — atomically increments a counter in a named store.

The TTL is applied when the key is created and never refreshed. A counter that bounds retries must expire a fixed time after it first appears; refreshing on every increment means a client that keeps retrying keeps the counter alive and the bound never resets.

Constants

INCR_SCRIPT 🔒

INCRBY, then set the expiry only if the key does not already have one. TTL returns a negative value when the key has no expiry, so the guard also repairs a key that somehow lost one. One round trip, atomic.

Functions

parse_by 🔒

Parses the optional by amount, which defaults to 1 and may be negative.

parse_refresh_ttl 🔒

Parses the optional refresh_ttl flag.
