Enum InvalidationMessage 

pub enum InvalidationMessage {
    Remove {
        key: String,
    },
    Update {
        key: String,
        value: Value,
        ttl_secs: Option<u64>,
    },
    RemovePattern {
        pattern: String,
    },
    RemoveBulk {
        keys: Vec<String>,
    },
}

Invalidation message types sent across cache instances via Redis Pub/Sub

Variants

Remove

Remove a single key from all cache instances

Fields

key: String

Update

Update a key with new value across all cache instances This is more efficient than Remove for hot keys as it avoids cache miss

Fields

key: String

value: Value

ttl_secs: Option<u64>

RemovePattern

Remove all keys matching a pattern from all cache instances Uses glob-style patterns (e.g., “user:”, “product:123:”)

Fields

pattern: String

RemoveBulk

Bulk remove multiple keys at once

Fields

keys: Vec<String>
