Method Detail

getMaxNestedArrays

public int getMaxNestedArrays()

Tune how much nested arrays are allowed on a redis response. This affects the parser performance.

Returns:

the configured max nested arrays allowance.

setMaxNestedArrays

public RedisConnectOptions setMaxNestedArrays(int maxNestedArrays)

Tune how much nested arrays are allowed on a redis response. This affects the parser performance.

Parameters:

maxNestedArrays - the configured max nested arrays allowance.

Returns:

fluent self.

isProtocolNegotiation

public boolean isProtocolNegotiation()

Should the client perform RESP protocol negotiation during the connection handshake. By default this is true, but there are situations when using broken servers it may be useful to skip this and always fallback to RESP2 without using the HELLO command.

Returns:

true to perform negotiation.

setProtocolNegotiation

public RedisConnectOptions setProtocolNegotiation(boolean protocolNegotiation)

Should the client perform REST protocol negotiation during the connection acquire. By default this is true, but there are situations when using broken servers it may be useful to skip this and always fallback to RESP2 without using the HELLO command.

Parameters:

protocolNegotiation - false to disable HELLO (not recommended) unless reasons...

Returns:

fluent self

getPassword

public String getPassword()

Get the default password for cluster/sentinel connections, if not set it will try to extract it from the current default endpoint.

Returns:

password

setPassword

public RedisConnectOptions setPassword(String password)

Set the default password for cluster/sentinel connections.

Parameters:

password - the default password

Returns:

fluent self

getEndpoints

public List<String> getEndpoints()

Gets the list of redis endpoints to use (mostly used while connecting to a cluster)

Returns:

list of socket addresses.

getEndpoint

public String getEndpoint()

Gets the redis endpoint to use

Returns:

the Redis connection string URI

setEndpoints

public RedisConnectOptions setEndpoints(List<String> endpoints)

Set the endpoints to use while connecting to the redis server. Only the cluster mode will consider more than 1 element. If more are provided, they are not considered by the client when in single server mode.

Parameters:

endpoints - list of socket addresses.

Returns:

fluent self.

addConnectionString

public RedisConnectOptions addConnectionString(String connectionString)

Adds a connection string (endpoint) to use while connecting to the redis server. Only the cluster mode will consider more than 1 element. If more are provided, they are not considered by the client when in single server mode.

Parameters:

connectionString - a string URI following the scheme: redis://[username:password@][host][:port][/database]

Returns:

fluent self.

See Also:

Redis scheme on iana.org

setConnectionString

public RedisConnectOptions setConnectionString(String connectionString)

Sets a single connection string (endpoint) to use while connecting to the redis server. Will replace the previously configured connection strings.

Parameters:

connectionString - a string following the scheme: redis://[username:password@][host][:port][/[database].

Returns:

fluent self.

Redis scheme on iana.org

getMaxWaitingHandlers

public int getMaxWaitingHandlers()

The client will always work on pipeline mode, this means that messages can start queueing. You can control how much backlog you're willing to accept. This methods returns how much handlers is the client willing to queue.

Returns:

max allowed queued waiting handlers.

setMaxWaitingHandlers

public RedisConnectOptions setMaxWaitingHandlers(int maxWaitingHandlers)

The client will always work on pipeline mode, this means that messages can start queueing. You can control how much backlog you're willing to accept. This methods sets how much handlers is the client willing to queue.

Parameters:

maxWaitingHandlers - max allowed queued waiting handlers.

Returns:

fluent self.

toJson

public JsonObject toJson()

Converts this object to JSON notation.

Returns:

JSON
