Docs Cloud Redpanda Connect Components Caches memory memory Type: CacheBuffer Available in: Cloud, Self-Managed Stores key/value pairs in a map held in memory. This cache is therefore reset every time the service restarts. Each item in the cache has a TTL set from the moment it was last edited, after which it will be removed during the next compaction. Common Advanced # Common config fields, showing default values label: "" memory: default_ttl: 5m compaction_interval: 60s init_values: {} # All config fields, showing default values label: "" memory: default_ttl: 5m compaction_interval: 60s init_values: {} shards: 1 The compaction interval determines how often the cache is cleared of expired items, and this process is only triggered on writes to the cache. Access to the cache is blocked during this process. Item expiry can be disabled entirely by setting the compaction_interval to an empty string. The field init_values can be used to prepopulate the memory cache with any number of key/value pairs which are exempt from TTLs: cache_resources: - label: foocache memory: default_ttl: 60s init_values: foo: bar These values can be overridden during execution, at which point the configured TTL is respected as usual. Fields default_ttl The default TTL of each item. After this period an item will be eligible for removal during the next compaction. Type: string Default: "5m" compaction_interval The period of time to wait before each compaction, at which point expired items are removed. This field can be set to an empty string in order to disable compactions/expiry entirely. Type: string Default: "60s" init_values A table of key/value pairs that should be present in the cache on initialization. This can be used to create static lookup tables. Type: object Default: {} # Examples init_values: Nickelback: "1995" Spice Girls: "1994" The Human League: "1977" shards A number of logical shards to spread keys across, increasing the shards can have a performance benefit when processing a large number of keys.
