Overview

Standard

Standard backend for MongoCacheStore

Description

Entreis are kept in a namespaced MongoDB collection. In a standard collection entries are only flushed from the collection with an explicit delete call or if auto_flush is enabled. If auto_flush is enabled the cache will flush all expired entries when auto_flush_threshold is reached. The threshold is based on a set number of cache instance writes.

Additional Options

The following options can be added to a MongoCacheStore constructor

options - Standard backend options

To see a list of core options see MongoCacheStore

:auto_flush - true | false

Default: true

If auto_flush is enabled the cache will flush all expired entries when auto_flush_threshold is reached.

:auto_flush_threshold - 10_000

Default: 10_000

A number representing the number of writes the when the cache should preform before flushing expired entries.
