ColdStartSession

Struct ColdStartSession

pub struct ColdStartSession<'a, K, V, S, Tls: TlsProvider> { /* private fields */ }

Expand description

A session object for injecting items directly into T1 during cold starts. By requiring a session object, we prevent accidental use of insert_t1 in normal hot paths which would bypass TLS batching and overload the daemon.

Implementations§

impl<'a, K, V, S, Tls: TlsProvider> ColdStartSession<'a, K, V, S, Tls>
where K: Hash + Eq + Send + Sync + Clone + 'static, V: Send + Sync + Clone + 'static, S: BuildHasher + Clone + Send + 'static,

pub fn warmup(&self, key: K, value: V)

Insert a key-value pair directly as a high-priority “genius” item. This bypasses the L1 probation filter, doesn’t use the thread-local batch buffer, and assigns the item the maximum survival rank (e.g. 255) and promotes it to T1 immediately.
