Touch

class Touch

Adjust the expiration time of a tagged cache item and its tag entries.

All-mode tag ZSET scores are the authoritative expiry used by stale pruning. A bare EXPIRE on the item key would desynchronize the scores: pruning would drop the entry while the key lives, and a later tag flush would miss it.

Methods

__construct(StoreContext $context)

Create a new touch operation instance.

bool
execute(string $key, int $seconds, array $tagIds)

Execute the touch operation.

string
touchTaggedScript()

Get the Lua script for touching a tagged value and its ZSET scores.
