Reliably connect to one of a pool of protomux-rpc servers.

Picks a random server to connect to, and keeps connecting to that server, unless it fails to respond, in which case it automatically switches over to another one.

npm i protomux-rpc-client-pool

Create a new pool. keys is a list of HyperDHT servers that expose the same protomux-rpc service. rpcClient is a Protomux RPC client instance.

opts include:

• retries : the number of times to retry a request with a different server before giving up. Default: 3.
• timeout : the default timeout for a single request attempt, in ms. Note that the maximal total time for a pool.request(...) call is roughly retries * timeout.

Makes a request for the specifed methodName to one of the servers in the pool, passing the args. If the server fails to respond, it automatically retries with other servers.

Throws a ProtomuxRpcClientPoolError.TOO_MANY_RETRIES error if the request attempt fails pool.retries times.

opts include:

• requestEncoding the request encoding of the RPC service
• responseEncoding the response encoding of the RPC service
• timeout the timeout to use for each request attempt (in ms). Defaults to pool.timeout.
