Adjust advanced settings to fine-tune connection behavior and manage how Martini interacts with Redis.

Property	Default	Description
Ping Before Activate Connection	`false`	Issues a PING command to check connection viability before activation.
Auto Reconnect	`true`	Enables automatic reconnection attempts on connection loss.
Cancel Commands On Reconnect Failure	`false`	Cancels queued commands if reconnection attempts fail.
Publish On Scheduler	`false`	Utilizes a dedicated scheduler for emitting reactive data signals.
Suspend Reconnect On Protocol Failure	`false`	Suspends automatic reconnection on protocol errors, requiring manual intervention.
Request Queue Size	`2147483647`	Configures the maximum size of the request queue for a connection.
Disconnected Behavior	`Default`	Determines behavior for command execution when the connection is disconnected.

SSL Configuration Properties

Secure Redis connections using SSL with these configuration options.

Property	Default	Description
SSL Provider	`JDK`	Choose between OpenSSL or JDK for SSL connections.
KeyStore File		Path to the KeyStore file for client certificates.
KeyStore Password		Password for the KeyStore file.
TrustStore File		Path to the TrustStore file for trusted certificates.
TrustStore Password		Password for the TrustStore file.
Start TLS	`false`	Initiates TLS for secure connections.

Socket Configuration Properties

Control the underlying TCP/IP socket behavior for Redis connections.

Property	Default	Description
Connect Timeout (ms)	`10000`	Timeout for establishing a connection, in milliseconds.
Keep Alive	`false`	Enables TCP keepalive messages to maintain the connection.
TCP No Delay	`false`	Disables Nagle's algorithm for reduced latency at the cost of potential increased bandwidth.

Connection Configuration Properties for Redis in Martini

Optimizing the connection pool and behavior of Redis connections is crucial for ensuring the efficiency and reliability of your Martini applications. The following connection configuration properties allow for detailed customization of how Martini manages Redis connections.

Connection Configuration Properties

Fine-tune your Redis connection pool and management settings using these properties:

Property	Default	Description
Connection Timeout (ms)	`-1`	Sets the connection timeout in milliseconds. A value of `-1` indicates no timeout.
Auto Flush Commands	`true`	Determines whether commands are automatically flushed.
Maximum Total	`8`	The maximum number of connections maintained in the pool. Negative values mean no limit.
Maximum Idle	`8`	The maximum number of idle connections in the pool. If `Minimum Idle` is higher, `Maximum Idle` is used instead.
Minimum Idle	`0`	The minimum number of idle connections in the pool.
Eviction Policy Name		Specifies the eviction policy when the database size limit is reached.
Time Between Eviction Runs (ms)	`-1`	Time in milliseconds before evicting connections. A value of `-1` disables eviction by default.
Evictable Idle Time (ms)	`1800000`	Minimum time an object may sit idle before being eligible for eviction, in milliseconds.
Soft Evictable Idle Time (ms)	`-1`	Minimum time an object may sit idle before it's eligible for eviction, ensuring a minimum number of idle objects remain.
Tests Per Eviction Run	`3`	The number of objects examined per eviction run. Negative values mean all connections are tested.
Evictor Shutdown Timeout (ms)	`10000`	Timeout for evictor shutdown upon pool closure, in milliseconds.
JMX Enabled	`false`	Toggles JMX monitoring for the connection pools.
JMX Name Base		Base name for JMX enabled pools.
JMX Name Prefix		Prefix for names assigned to JMX enabled pools.
Maximum Wait (ms)	`0`	Time to wait for an available connection.
Block When Exhausted	`true`	When `false`, an error occurs if a connection request is made when no connections are available.
LIFO	`true`	Determines if the pool returns idle objects in last-in-first-out order.
Fairness	`false`	Ensures threads receive available instances in the order they were requested.
Test On Create	`false`	Tests connections upon creation.
Test On Borrow	`false`	Tests connections upon borrowing from the pool.
Test On Return	`false`	Tests connections upon returning to the pool.
Test While Idle	`false`	Tests connections while idle.

These configuration properties provide extensive control over the behavior of Redis connections within Martini, enabling developers to optimize their applications for performance, reliability, and security. By adjusting these settings, you can ensure that your Redis connections are managed efficiently, according to your application's specific needs.
