Tip

Prior to release 4.0.22, Disk-Backed History stores are located here ~yourIgnitionInstance\user-lib\cls\data\h2

From release 4.0.22, Disk-Backed History store are located here ~yourIgnitionInstance\data\modules\com.cirrus-link\com.cirruslink.injector.aws.gateway\h2

From release 4.0.25, the base path for the database location of the Disk-Backed History store is configurable:

  • The default base path for Linux is ~yourIgnitionInstance\data\modules and the database will be included in the Ignition GWBK
  • The default location for Windows Linux is ~yourIgnitionInstance\data\user-lib and the database will not be included in the Ignition GWBK
  • The database file will be created in this directory under the base path com.cirrus-link\com.cirruslink.injector.aws.gateway\h2


Each of these tabs is described in detail in the following sections.

...

  • Partition Key Count
    • The number of partition keys to use for inserts
  • Partition Key
    • An optional partition key pattern that supports token substitution for the following message fields: ${group}, ${edgenode}, ${device}.  This should only be configured if explicitly defined partition keys are necessary when inserting into the Kinesis Stream.
  • Max Message Size
    • The maximum message size in bytes to send. Generally, this should match the max message size allowed by AWS Kinesis.

  • H2 Database Directory
    • Directory to store the H2 Database in. Applicable for Disk-backed history store only
    • The default base path for Linux is ~yourIgnitionInstance\data\modules and the database will be included in the Ignition GWBK
    • The default location for Windows Linux is ~yourIgnitionInstance\data\user-lib and the database will not be included in the Ignition GWBK
    • The database file will be created in this directory under the base path com.cirrus-link\com.cirruslink.injector.aws.gateway\h2
  • H2 Database Port

As you can see, the Sparkplug settings can be used to either hard-code these IDs, or leave them blank so that the Agent will scan and discover them based on the tag tree layout. For more information see the Cloud Injector Tag Agents and Tag Trees document.

Advanced

  • Send All Properties
    • Send all properties, including non-default properties, in Sparkplug BIRTH messages
  • Filtered Properties
    • A semicolon delimited list of Tag properties to filter/block from being published.  These should typically not be modified unless there is an explicit requirement that a specific property is needed to be added or removed from the default.
