Coherence is supported on Go versions 1.19 and above:

Install the coherence implementation:

go get

Before running or testing this implementation, you must ensure a Coherence cluster is available. For local development, we recommend using the Coherence CE Docker image; it contains everything necessary for the client to operate correctly.

To start a Coherence cluster using Docker, issue the following:

docker run -d -p 1408:1408

See the documentation here on connection options when creating a Coherence session.


Import the storage package.

import ""

You can use the following possibilities to create a storage:

// Initialize default config, to connect to localhost:1408 using plain text
store, err := coherence.New()

// Initialize custom config to connect to a different host/port and use plaint ext.
store, err := coherence.New(coherence.Config{
Address: "my-host:myport",

// Initialize to connect with TLS enabled with your own tls.Config
tlsConfig := config := &tls.Config{...}

store, err := coherence.New(coherence.Config{
Address: "my-host:myport",
TLSConfig: tlsConfig,

Note: If you create two stores using coherence.New() they will effectivity be idential. If you wish to have two separate stores, then you can use:

store1, err := coherence.New(Config{ScopeName: "scope1"})
store2, err := coherence.New(Config{ScopeName: "scope2"})


// Config defines configuration options for Coherence connection.
type Config struct {
// Address to connect to, defaults to "localhost:1408"
Address string

// Timeout is the default session timeout to connect to Coherence, defaults to 30s
Timeout time.Duration

// ScopeName defines a scope allowing for multiple storage sessions
ScopeName string

// Reset indicates if the store should be reset after being created
Reset bool

// TLSConfig specifies tls.Config to use when connecting, if nil then plain text is used
TLSConfig *tls.Config

Default Config

var DefaultConfig = Config{
Address: "localhost:1408",
Timeout: time.Duration(30) * time.Millisecond,
ScopeName: defaultScopeName,
Reset: false,
