Server pool

data ServerPool Source

Non-empty set of server locations. The active server will always be used until any HTTP communications fail.

newServerPool :: Server -> [Server] -> IO (IORef ServerPool)Source

Create a non-empty server pool. You must specify at least one server location to create a pool.

activeServer :: IORef ServerPool -> IO Server Source

Get a server from the pool.

failover :: IORef ServerPool -> IO ()Source

Move the current server to the backup pool and pick one of the backup server as the new active server. Currently the scheduler works in round-robin fashion.
