Redis Connector 5.2 Reference - Mule 4

Support Version: Select

Release Notes: Redis Connector Release Notes

You can set configurations in Expression mode, except when Redis Connector is used in conjunction with Object Store Connector, which does not support Expression mode.

Configurations

Redis

Parameters

Name Type Description Default Value Required

Name

String

The name for this configuration. Connectors reference the configuration with this name.

x

Connection

The connection types to provide to this configuration.

x

Expiration Policy

Expiration Policy

Configures the minimum amount of time that a dynamic configuration instance can remain idle before Mule considers it eligible for expiration. This does not mean that the instance expires at the exact moment that it becomes eligible. Mule purges the instances as appropriate.

Connection Types

Clustered
Parameters
Name Type Description Default Value Required

Endpoint identification algorithm

Enumeration, one of:

  • HTTPS

  • LDAPS

  • DISABLED

The endpoint identification algorithm used by clients to validate the server hostname. The default value is an empty string, which means that this functionality is disabled. Clients, including client connections created by the broker for inter-broker communication, verify that the broker hostname matches the hostname in the broker’s certificate.

DISABLED

TLS Configuration

TLS

Configures TLS. If you are running the Mule app securely by using the HTTPS protocol, you must configure TLS in the connector.

Name

Type

Description

Default Value

Required

Cluster Hosts

String

Redis cluster hosts separated by commas and having format host:port. Use this field to have the connector access a Redis cluster.

x

Connection Timeout

Number

Connection timeout in milliseconds.

2000

Password

String

Redis password. Set this value if the server requires authentication.

Entry TTL

Number

The default time to live to be set on keys stored through connector.

Reconnection

Reconnection

When the application is deployed, a connectivity test is performed on all connectors. If set to true, deployment fails if the test doesn’t pass after exhausting the associated reconnection strategy.

Revocation Check

Trust Store

Field Type Description Default Value Required

Path

String

The location (which will be resolved relative to the current classpath and file system, if possible) of the trust store.

Password

String

The password used to protect the trust store.

Type

String

The type of store used.

Algorithm

String

The algorithm used by the trust store.

Insecure

Boolean

If true, no certificate validations will be performed, rendering connections vulnerable to attacks. Use at your own risk.

Path

String

The location (which will be resolved relative to the current classpath and file system, if possible) of the key store.

Type

String

The type of store used.

Alias

String

When the key store contains many private keys, this attribute indicates the alias of the key that should be used. If not defined, the first key in the file will be used by default.

Key Password

String

The password used to protect the private key.

Password

String

The password used to protect the key store.

Algorithm

String

The algorithm used by the key store.

Standard Revocation Check

Field Type Description Default Value Required

Only End Entities

Boolean

Only verify the last element of the certificate chain.

Prefer Crls

Boolean

Try CRL instead of OCSP first.

No Fallback

Boolean

Do not use the secondary checking method (the one not selected before).

Soft Fail

Boolean

Avoid verification failure when the revocation server can not be reached or is busy.

Custom Ocsp Responder

Field Type Description Default Value Required

Url

String

The URL of the OCSP responder.

Cert Alias

String

Alias of the signing certificate for the OCSP response (must be in the trust store), if present.

Crl File

Field Type Description Default Value Required

Path

String

The path to the CRL file.

Reconnection

Field Type Description Default Value Required

Fails Deployment

Boolean

When the application is deployed, a connectivity test is performed on all connectors. If set to true, deployment fails if the test doesn’t pass after exhausting the associated reconnection strategy.

Reconnection Strategy

The reconnection strategy to use.

Reconnect

Field Type Description Default Value Required

Frequency

Number

How often in milliseconds to reconnect.

Count

Number

How many reconnection attempts to make.

blocking

Boolean

If false, the reconnection strategy runs in a separate, non-blocking thread.

true

Reconnect Forever

Field Type Description Default Value Required

Frequency

Number

How often in milliseconds to reconnect.

blocking

Boolean

If false, the reconnection strategy runs in a separate, non-blocking thread.

true

Expiration Policy

Field Type Description Default Value Required

Max Idle Time

Number

A scalar time value for the maximum amount of time a dynamic configuration instance should be allowed to be idle before it’s considered eligible for expiration.

Time Unit

Enumeration, one of:

  • NANOSECONDS

  • MICROSECONDS

  • MILLISECONDS

  • SECONDS

  • MINUTES

  • HOURS

  • DAYS

A time unit that qualifies the maxIdleTime attribute

Subscribe Channel Attributes

Field Type Description Default Value Required

Channel

String

Repeatable In Memory Stream

Field Type Description Default Value Required

Initial Buffer Size

Number

The amount of memory that will be allocated to consume the stream and provide random access to it. If the stream contains more data than can be fit into this buffer, then the buffer expands according to the bufferSizeIncrement attribute, with an upper limit of maxInMemorySize.

Buffer Size Increment

Number

This is by how much the buffer size will be expanded if it exceeds its initial size. Setting a value of zero or lower means that the buffer should not expand, meaning that a STREAM_MAXIMUM_SIZE_EXCEEDED error is raised when the buffer gets full.

Max Buffer Size

Number

The maximum amount of memory to use. If more memory is used, a STREAM_MAXIMUM_SIZE_EXCEEDED error is raised. A value lower than or equal to zero means no limit.

Buffer Unit

Enumeration, one of:

  • BYTE

  • KB

  • MB

  • GB

The unit in which all these attributes are expressed

Repeatable File Store Stream

Field Type Description Default Value Required

Max In Memory Size

Number

Defines the maximum memory that the stream should use to keep data in memory. If more than that is consumed then it will start to buffer the content on disk.

Buffer Unit

Enumeration, one of:

  • BYTE

  • KB

  • MB

  • GB

The unit in which maxInMemorySize is expressed

Redelivery Policy

Field Type Description Default Value Required

Max Redelivery Count

Number

The maximum number of times a message can be redelivered and processed unsuccessfully before triggering process-failed-message

Use Secure Hash

Boolean

Whether to use a secure hash algorithm to identify a redelivered message.

Message Digest Algorithm

String

The secure hashing algorithm to use. If not set, the default is SHA-256.

Id Expression

String

Defines one or more expressions to use to determine when a message has been redelivered. This property may only be set if useSecureHash is false.

Object Store

Object Store

The object store where the redelivery counter for each message is going to be stored.
