/*
Package pool provides a wrapper for several FrostFS API clients.
The main component is Pool type. It is a virtual connection to the network
and provides methods for executing operations on the server. It also supports
a weighted random selection of the underlying client to make requests.
Create pool instance with 3 nodes connection.
This InitParameters will make pool use 192.168.130.71 node while it is healthy. Otherwise, it will make the pool use
192.168.130.72 for 90% of requests and 192.168.130.73 for remaining 10%.
:
var prm pool.InitParameters
prm.SetKey(key)
prm.AddNode(NewNodeParam(1, "192.168.130.71", 1))
prm.AddNode(NewNodeParam(2, "192.168.130.72", 9))
prm.AddNode(NewNodeParam(2, "192.168.130.73", 1))
// ...
p, err := pool.NewPool(prm)
// ...
Connect to the FrostFS server:
err := p.Dial(ctx)
// ...
Execute FrostFS operation on the server:
var prm pool.PrmContainerPut
prm.SetContainer(cnr)
// ...
res, err := p.PutContainer(context.Background(), prm)
// ...
Execute FrostFS operation on the server and check error:
var prm pool.PrmObjectHead
prm.SetAddress(addr)
// ...
res, err := p.HeadObject(context.Background(), prm)
if client.IsErrObjectNotFound(err) {
// ...
}
// ...
Close the connection:
p.Close()
