cache

module:cache

Description:

• Cache module for shared cache and subscriptions.

  Some drivers (Redis) may support TTL so global options.ttl or local options.ttl can be used for put/incr operations and it will honored if it is suported.

  For caches that support maps, like Redis the options.mapName can be used with get/put/incr/del to work with maps and individual keys inside maps.

  All methods use options.cacheName for non-default cache. If it is an array then a client will be picked sequentially by maintaining internal sequence number.

  Empty default client always exists, it can be overridden to make default some other driver

  All public cache.get|put|incr|del|lock|unlock|limiter operations have corresponding promisifed methods starting with a, like cache.get -> cache.aget.

  To enable stats collection for a cache it must be enabled with config: cache-redis-options-metrics=1

Example

cache-default=redis://
cache-redis=redis://?bk-enable_offline_queue=1
cache-config={ "limiter": "local://", "redis": "redis://" }
