Implement custom LVQ Key and Non-Destructive in broker - protocol agnostic
Make feature configurable via broker.xml, core apis and activemqservercontrol
Add last-value-key test cases
Add non-destructive with lvq test cases
Add non-destructive with expiry-delay test cases
Update documents
Add new methods to support create, update with new attributes
Refactor to pass through queue-attributes in client side methods to reduce further method changes for adding new attributes in future and avoid methods with endless parameters. (note: in future this should prob be done server side too)
Update existing test cases and fake impls for new methods/attributes
- Split protocols into individual chapters
- Reorganize summary to flow more logically
- Fill in missing parameters in configuration index
- Normalize spaces for ordered and unordered lists
- Re-wrap lots of text for readability
- Fix incorrect XML snippets
- Normalize table formatting
- Improve internal links with anchors
- Update content to reflect new address model
- Resized architecture images to avoid excessive white-space
- Update some JavaDoc
- Update some schema elements
- Disambiguate AIO & ASYNCIO where necessary
- Use URIs instead of Objects in code examples
Quorum voting is used by both the live and the backup to decide what to do if a replication connection is disconnected.
Basically, the server will request each live server in the cluster to vote as to whether it thinks the server it is replicating to or from is still alive.
You can also configure the time for which the quorum manager will wait for the quorum vote response.
Currently, the value is hardcoded as 30 sec. We should change this 30-second wait to be configurable.
This option was removed in JRE 10 and its presence causes error on startup.
Artemis still does not compile on JDK 9 and up, so what I tried was
to compile on JDK 1.8 and then start Artemis on 1.8 and 10.
That now works for me.
It avoid using the system clock to perform the locks logic
by using the DBMS time.
It contains several improvements on the JDBC error handling
and an improved observability thanks to debug logs.
JdbcNodeManager is configured to use the same network timeout
value of the journal and to validate all the timeout values
related to a correct HA behaviour.
It allows a user to customize the max allowed distance between system and DB time,
improving HA reliability by shutting down the broker when the misalignment
exceeds configured limit.
The JDBC Lock Acquisition Timeout is no longer exposed to any user configuration and defaulted to infinite to match the behaviour of the journal (file-based) one.
