*For `gun` adapter*
-Advanced settings for connections pool. Pool with opened connections. These connections can be reused in worker pools.
+Settings for HTTP connection pool.
-For big instances it's recommended to increase `config :pleroma, :connections_pool, max_connections: 500` up to 500-1000.
-It will increase memory usage, but federation would work faster.
-
-* `:checkin_timeout` - timeout to checkin connection from pool. Default: 250ms.
-* `:max_connections` - maximum number of connections in the pool. Default: 250 connections.
-* `:retry` - number of retries, while `gun` will try to reconnect if connection goes down. Default: 1.
-* `:retry_timeout` - time between retries when `gun` will try to reconnect in milliseconds. Default: 1000ms.
-* `:await_up_timeout` - timeout while `gun` will wait until connection is up. Default: 5000ms.
+* `:connection_acquisition_wait` - Timeout to acquire a connection from pool.The total max time is this value multiplied by the number of retries.
+* `connection_acquisition_retries` - Number of attempts to acquire the connection from the pool if it is overloaded. Each attempt is timed `:connection_acquisition_wait` apart.
+* `:max_connections` - Maximum number of connections in the pool.
+* `:await_up_timeout` - Timeout to connect to the host.
+* `:reclaim_multiplier` - Multiplied by `:max_connections` this will be the maximum number of idle connections that will be reclaimed in case the pool is overloaded.
### :pools
*For `gun` adapter*
-Advanced settings for workers pools.
+Settings for request pools. These pools are limited on top of `:connections_pool`.
There are four pools used:
-* `:federation` for the federation jobs.
- You may want this pool max_connections to be at least equal to the number of federator jobs + retry queue jobs.
-* `:media` for rich media, media proxy
-* `:upload` for uploaded media (if using a remote uploader and `proxy_remote: true`)
-* `:default` for other requests
+* `:federation` for the federation jobs. You may want this pool's max_connections to be at least equal to the number of federator jobs + retry queue jobs.
+* `:media` - for rich media, media proxy.
+* `:upload` - for proxying media when a remote uploader is used and `proxy_remote: true`.
+* `:default` - for other requests.
For each pool, the options are:
-* `:size` - how much workers the pool can hold
+* `:size` - limit to how much requests can be concurrently executed.
* `:timeout` - timeout while `gun` will wait for response
-* `:max_overflow` - additional workers if pool is under load
+* `:max_waiting` - limit to how much requests can be waiting for others to finish, after this is reached, subsequent requests will be dropped.
