reconnect(+Boolean)

If true, try to reconnect to the service when the connection seems lost. Default is true for connections specified using redis_server/3 and false for explictly opened connections.

user(+User)

If version(3) and password(Password) are specified, these are used to authenticate using the HELLO command.

password(+Password)

Authenticate using Password

version(+Version)

Specify the connection protocol version. Initially this is version 2. Redis 6 also supports version 3. When specified as 3, the HELLO command is used to upgrade the protocol.

tls(true)

When specified, initiate a TLS connection. If this option is specified we must also specify the cacert, key and cert options.

cacert(+File)

CA Certificate file to verify with.

cert(+File)

Client certificate to authenticate with.

key(+File)

Private key file to authenticate with.

sentinels(+ListOfAddresses)

Used together with an Address of the form sentinel(MasterName) to enable contacting a network of Redis servers guarded by a sentinel network.

sentinel_user(+User)

sentinel_password(+Password)

Authentication information for the senitels. When omitted we try to connect withour authentication.

Instead of using these predicates, redis/2 and redis/3 are normally used with a server name argument registered using redis_server/3. These predicates are meant for creating a temporary paralel connection or using a connection with a blocking call.

Arguments:

Address

- is a term Host:Port, unix(File) or the name of a server registered using redis_server/3. The latter realises a new connection that is typically used for blocking redis commands such as listening for published messages, waiting on a list or stream.

Compatibility

- redis_connect(-Connection, +Host, +Port) provides compatibility to the original GNU-Prolog interface and is equivalent to redis_connect(Host:Port, Connection, []).
