Function freeTrackingRadixTreeCallback

app/redis-6.2.6/src/tracking.c:410–412

This function is called when one or all the Redis databases are * flushed. Caching keys are not specific for each DB but are global: * currently what we do is send a special notification to clients with * tracking enabled, sending a RESP NULL, which means, "all the keys", * in order to avoid flooding clients with many invalidation messages * for all the keys they may hold. */

 * for all the keys they may hold.
