How was the modification of data processing methods in the crawlers system carried out?

In broadcast systems, modification of data processing methods is usually achieved through several approaches:

1. Configuration files — changing processing parameters without recompiling the code, such as modifying filters or data routes.

2. Updating microservices or components — if processing is implemented as separate services, modification occurs through deploying new versions with altered logic.

3. Using scripts or plugins — for flexibility, some systems allow connecting scripts or plugins that change data processing behavior on the fly.

4. CI/CD processes — automating the deployment of new versions with modified processing methods through pipelines.

For example, if a broadcast system has a service that filters messages, changing the filtering logic can be done by updating the configuration or replacing the service with a new version with an improved algorithm. In DevOps practices, this is usually accompanied by testing and monitoring to ensure that the changes do not disrupt the system's operation.
