- ## Caching ##
-
- # Caching can be configured through the following options.
- #
- # A cache 'factor' is a multiplier that can be applied to each of
- # Synapse's caches in order to increase or decrease the maximum
- # number of entries that can be stored.
- #
- # The configuration for cache factors (caches.global_factor and
- # caches.per_cache_factors) can be reloaded while the application is running,
- # by sending a SIGHUP signal to the Synapse process. Changes to other parts of
- # the caching config will NOT be applied after a SIGHUP is received; a restart
- # is necessary.
-
- # The number of events to cache in memory. Not affected by
- # caches.global_factor.
- #
- #event_cache_size: 10K
-
- caches:
- # Controls the global cache factor, which is the default cache factor
- # for all caches if a specific factor for that cache is not otherwise
- # set.
- #
- # This can also be set by the "SYNAPSE_CACHE_FACTOR" environment
- # variable. Setting by environment variable takes priority over
- # setting through the config file.
- #
- # Defaults to 0.5, which will half the size of all caches.
- #
- #global_factor: 1.0
-
- # A dictionary of cache name to cache factor for that individual
- # cache. Overrides the global cache factor for a given cache.
- #
- # These can also be set through environment variables comprised
- # of "SYNAPSE_CACHE_FACTOR_" + the name of the cache in capital
- # letters and underscores. Setting by environment variable
- # takes priority over setting through the config file.
- # Ex. SYNAPSE_CACHE_FACTOR_GET_USERS_WHO_SHARE_ROOM_WITH_USER=2.0
- #
- # Some caches have '*' and other characters that are not
- # alphanumeric or underscores. These caches can be named with or
- # without the special characters stripped. For example, to specify
- # the cache factor for `*stateGroupCache*` via an environment
- # variable would be `SYNAPSE_CACHE_FACTOR_STATEGROUPCACHE=2.0`.
- #
- per_cache_factors:
- #get_users_who_share_room_with_user: 2.0
-
- # Controls whether cache entries are evicted after a specified time
- # period. Defaults to true. Uncomment to disable this feature.
- #
- #expire_caches: false
-
- # If expire_caches is enabled, this flag controls how long an entry can
- # be in a cache without having been accessed before being evicted.
- # Defaults to 30m. Uncomment to set a different time to live for cache entries.
- #
- #cache_entry_ttl: 30m
-
- # This flag enables cache autotuning, and is further specified by the sub-options `max_cache_memory_usage`,
- # `target_cache_memory_usage`, `min_cache_ttl`. These flags work in conjunction with each other to maintain
- # a balance between cache memory usage and cache entry availability. You must be using jemalloc to utilize
- # this option, and all three of the options must be specified for this feature to work.
- #cache_autotuning:
- # This flag sets a ceiling on much memory the cache can use before caches begin to be continuously evicted.
- # They will continue to be evicted until the memory usage drops below the `target_memory_usage`, set in
- # the flag below, or until the `min_cache_ttl` is hit.
- #max_cache_memory_usage: 1024M
-
- # This flag sets a rough target for the desired memory usage of the caches.
- #target_cache_memory_usage: 758M
-
- # 'min_cache_ttl` sets a limit under which newer cache entries are not evicted and is only applied when
- # caches are actively being evicted/`max_cache_memory_usage` has been exceeded. This is to protect hot caches
- # from being emptied while Synapse is evicting due to memory.
- #min_cache_ttl: 5m
-
- # Controls how long the results of a /sync request are cached for after
- # a successful response is returned. A higher duration can help clients with
- # intermittent connections, at the cost of higher memory usage.
- #
- # By default, this is zero, which means that sync responses are not cached
- # at all.
- #
- #sync_response_cache_duration: 2m
