Touch

class Touch

Adjust the expiration time of a cached item and its tag metadata.

Any-mode tag hash fields and reverse indexes carry their own TTLs, and flush treats them as authoritative membership. A bare EXPIRE on the key would let the key outlive its tag metadata, making a later tag flush miss a still-live key.

Methods

__construct(StoreContext $context)

Create a new touch operation instance.

bool
execute(string $key, int $seconds)

Execute the touch operation.

string
touchWithTagsScript()

Get the Lua script for touching a value and its tag metadata.
