Closed Issues in 6.2.2_HF-001 (This Release)

BE-31022
The retry mechanism for cluster locks fails to handle lock calls when timeout 
is set to -1 (forever) and thus blocking the inference agent.   

BE-31018
Instance assertion for duplicate check in the working memory is running 
slow for a large data set when be.engine.id.useLegacy is set to false.

BE-31017
While creating concepts from event payload, extId in the child element 
is not used and incorrect extIds are set for parent and child elements.

BE-31008
When a project is running for a long time with a continuous query 
containing aggregate functions, the memory consumption keeps growing. 
A new property be.engine.query.optimize.aggregate has been added 
to fix this. Set its value to true to enable the optimization 
of aggregate functions. The default value of the property is false.

BE-31001
After migrating schema from legacy ID to the new key-based ID lookup, 
the TIBCO BusinessEvents application is not working when there are  
unreferenced records in the database.
This is now fixed. Set the be.engine.id.migrated.allowAdjust to true 
in your project CDD or be-engine.tra file for migrating applications 
with unreferenced records.
 
BE-30994
An external JDBC client can connect to TIBCO BusinessEvents Apache 
Ignite cluster without any SSL connectivity or user authentication.
Now, you can add the “enable-authentication” property and set its value 
to true in the store.xml file to enable the user authentication 
for Apache Ignite.
