I am adding three attributes to Address-settings:
* page-limit-bytes: Number of bytes. We will convert this metric into max number of pages internally by dividing max-bytes / page-size. It will allow a max based on an estimate.
* page-limit-messages: Number of messages
* page-full-message-policy: fail or drop
We will now allow paging, until these max values and then fail or drop messages.
Once these values are retracted, the address will remain full until a period where cleanup is kicked in by paging. So these values may have a certain delay on being applied, but they should always be cleared once cleanup happened.
- From now on we will save snapshots of page-counters on the journal (basically for compatibility with previous verions).
And we will recount the records on startup.
- While the rebuild is being done the value from the previous snapshot is still available with current updates.
Attempt to standardize all Logger declaration to a singular variable name
which makes the code more consistent and make finding usages of loggers in
the code a bit easier.
This is caused by too many entries on the HashMap for ThreadLocals.
Also: I'm reviewing some readlock usage on the StorageManager to simplify things a little bit.
Paging only removes files at the beginning of the stream...
Say you have paged files 1 through 1000...
if all the messages are ack, but one message on file 1 is missing an ack, all the 999 subsequent files would not be removed until all the messages on file 1 is ack.
This was working as engineered, but sometimes devs don't have complete control on their app.
With this improvement we will now remove messages in the middle of the stream as well.
There is also some improvement to how browsing and page work with this
scenario - avoid paging, if address is full chain another broker and produce to the head, consume from the tail using producer and consumer roles to partition connections. When tail is drained, drop it.
- adds a option to treat an idle consumer as slow
- adds basic support for credit based address blocking ARTEMIS-2097
- adds some more visiblity to address memory usage and balancer attribute modifier operations
