How often does the system delete Flow Designer related entries from the var_dictionary table if not used in a year?

• A. Monthly
• B. Weekly
• C. Daily
• D. Yearly

Answer: (A)

Flow Designer stores its variables and related metadata in var_dictionary. When an entry isn’t referenced in a Flow Designer context for a year, it’s considered unused and eligible for cleanup. The system runs this cleanup on a monthly cadence, removing those stale entries in a single pass each month. This monthly schedule keeps the dictionary lean without imposing frequent, disruptive housekeeping, while still removing old unused data regularly. If an entry gets used again, its last-used date is updated, so it won’t be deleted. Daily or weekly cleanups would add unnecessary overhead, and waiting a whole year would let unused data accumulate longer than desirable.
