edgeCore New Features

edgeCore Visualization Platform updated to Angular v9 providing:

• (Upgrade Required) – Custom HTML Template Visualizations will update required.
• Improved client-side logging of HTML Template errors; providing improved references to specific HTML Template Visualization the error occurs.

Login Page

• Updated default login page, replacing Angular dependency with JQuery.

General Updates

EC-447 – About screen product icon updates.

EC-117 – Emit metric for visualization/pipeline construct usage.

EC-399 – Checkhealth URL now provides additional information including is the server licensed, is it clustered, and if clustered is the cluster available (to help determine if admin tasks are available).

edgeCore Pipeline

EC-32 – ForEach transform – This transform iterates over each record in one source dataset (master), and for each row, it uses an attribute value to retrieve data from another dataset (detail) with the attribute value from the master data as the nodeVar for the detail data. The aggregation of this returned detail data is the result of the ForEach transform.  The additional benefit of setting max requests used to queue up parallel requests on a detailed source.

EC-28 – Data cache persistence – Feeds can be flagged as persisted, which will store the results to the filesystem instead of just in memory. This data is then available following a restart before the feed would otherwise have data from a new query. This also reduces memory consumption on the server for persisted data.

EC-446 – Javascript expression evaluation to include moment; when configuring properties like a WebData URI or WebData Request Body:  {js:moment().format(“YYYY-MM-DD”)} or {js.time.now().format(“YYYY-MM-DD’T’HH:mm:ss”)}

EC-80 – Added ability to hide system nodes in the Pipeline.

EC-288 – H2 Upgrade 1.4.199+ from 1.4.196 (general performance gains/improvements).

EC-397 – Unable to use secVars (all the Vars) in ENV settings for script sources.

edgeCore Known Issues

Custom Login Page Compatibility

Login pages built on versions prior to edgeCore v4.1 are not compatible.  An upgrade script is included to help stash custom login pages into ‘static-web/login-pre4.1’ and the customizations will require manual migration to the new default template.

Bootstrap 4 Updates

Due to the significant upgrade to Bootstrap 4, systems with customizations in the following areas should be tested to determine if they will require updates:

HTML Template Visualizations

Example: Glyphicons are no longer included. If you have custom HTML Templates that used them, in v3.11 they will all be empty.

Common Table Expression ‘WITH’ Clauses

edgeCore uses the H2 database in support of the SQL Transforms. SQL that uses Common Table Expression (CTE) ‘WITH’ clauses have been identified as causing two issues.

• Lock Timeouts: Transforms fail to run as temporary tables fail to be cleaned up.
• Memory Leaks: The temporary table results are not being cleaned up properly in all instances, and it will trigger Out Of Memory on the JVM.
  For additional information on this known issue, and remediation options, see SQL Transform.
• Errors connecting to 3rd party https webdata/webcontent sources.

edgeCore fails to connect over HTTPS to backend data sources.  In this case, one likely solution is to enable SNI, this is a global configuration so on some systems it might have the opposite affect.

# — SNI Options; may need to be enabled when connecting to 3rd party https webdata/webcontent sources.

ENABLE_SNI=true
