Recommended Versions for FLOWX.AI 3.4.1 ☑️

​

Additional configuration

This section outlines the supplementary configurations required to leverage the newly introduced features within FLOWX.AI (for a smooth transition please check first what’s new in 3.4.0).

​

Scheduler configuration

scheduler:
  thread-count: 30  # Configure the number of threads to be used for sending expired messages.
  callbacks-thread-count: 60 # Configure the number of threads for handling Kafka responses, whether the message was successfully sent or not
  cronExpression: "*/10 * * * * *" #every 10 seconds
  retry: # new retry mechanism
    max-attempts: 3
    seconds: 1
    thread-count: 3
    cronExpression: "*/10 * * * * *" #every 10 seconds
  cleanup:
    cronExpression: "*/25 * * * * *" #every 25 seconds

​

Explanation

• SCHEDULER_THREAD_COUNT - Used to configure the number of threads to be used for sending expired.
• CALLBACKS_THREAD_COUNT - Used to configure the number of threads for handling Kafka responses, whether the message was successfully sent or not.

​

New retry mechanism

• SCHEDULER_RETRY_THREAD_COUNT - Specify the number of threads to use for resending messages that need to be retried.
• SCHEDULER_RETRY_MAX_ATTEMPTS - This configuration parameter sets the number of retry attempts. For instance, if it’s set to 3, it means that the system will make a maximum of three retry attempts for message resending.
• SCHEDULER_RETRY_SECONDS - This configuration parameter defines the time interval, in seconds, for retry attempts. For example, when set to 1, it indicates that the system will retry the operation after a one-second delay.

Revised Cache Key Organization

To ensure a smooth transition for the 3.4.1 release, it is crucial to make use of the clear cache endpoint with the following request body:

Request:

POST /api/internal/cache/clear

Request body:

{
    "cacheNames": [
        "events",
        "admin",
        "allowedSwimlanes",
        "initiatedProcessFromStartEvent",
        "flowx:core"
        ]
}
