[Appendix]

Properties: Streams

The majority of configuration options for the server are set in the Streams.properties file in the <appdata> directory (e.g., C:\streamsserverdata\). If this file does not exist when the server starts, it will create it with all default values. When the server starts after an upgrade, it may add new properties and remove deprecated ones.

You can optionally move sensitive properties like passwords and URLs from this file, where they are stored in clear text, into a file named Secret.properties in the same directory. The Secret.properties file stores values encrypted, and you can manage it with PCLI. A property can only be defined in one of these files at a time.

The following properties can be set in the property files:

 

Property

Access

Attribute

access.administrator.groups

Description

The role that is mapped to the administrator group.

Default Value

Access

Attribute

access.administrator.users

Description

Normally administrator access should be handled with the access.adminstrator.groups mapping, but for scenarios where the authentication cannot provide roles or you want to make exceptions for specific users, you can list individual usernames in this property.

Default Value

 

Property

·         The event processor create topic gets the partition count for that topic.

If the topic exists, it checks for an existing partition count and deletes the topic if it has a different value, and then creates it with the provided partition count.

·         Kafka server with auto topic creation on connect will cause issues due to preemptive metric collector component.

Attribute

repository.startup.filesystemcheck

Description

If set to true, server runs on startup to verify the repository integrity and reports any of the following issues:

·         a deleted /HEAD file,

·         a modified /HEAD,

·         a modified /refs/heads/master file,

·         any file deleted inside /objects/ (e.g., /objects/94/443eec118fb8bb2021071896ff7d386a9c9518),

·         any file modified inside /objects/.

NOTE: There may be dangling files in the /objects/ directory or those that are not in use. These files are typically results of failed saves and/or sync conflicts. The check may or may not detect deleted or modified dangling files, but that is not critical.

Server Downgrade
