Additional Components#

This section describes the requirements for additional required components that must be running for a successful installation and operation of Critical Manufacturing MES. These requirements will vary depending on the usage of each component.

Kafka#

In regards to Kafka, the system requirements might change depending on several key factors such as:

  • message volume (count and size)
  • throughput
  • number of partitions
  • replication factor
  • data retention policies

Proper benchmarking and monitoring of Kafka is essential for fine-tuning resource allocation.

ACLs#

To simplify the setup of ACLs by system administrators, Kafka topics created by MES adhere to a standardized naming convention. For example, if the system name is "MESIntegrationEnvironment", all kafka topics will be created with the prefix of the system name in lower case. So, in this case, all kafka topics will have the prefix of "mesintegrationenvironment" or "_mesintegrationenvironment".

The user used by the system must have at least the following permissions:

  • Topic Permissions

    • Alter
    • AlterConfigs
    • Create
