--------------------------------
Summary: Ability to set percent and exact values to storeUsage,
tempUsage and per destination policies
Key: AMQ-4851
URL: https://issues.apache.org/jira/browse/AMQ-4851
Project: ActiveMQ
Issue Type: New Feature
Components: Broker, Message Store
Affects Versions: 5.9.0
Reporter: Attila Nagy
Priority: Minor
It's possible to specify absolute values to storeUsage and tempUsage in bytes
and usage percent to storeUsageHighWaterMark in per destination policies.
I would like to set them the other way: set storeUsage to a relative (percent)
value and limit a queue to given bytes.
The rationale behind this: I use a compressed file system, which compresses
messages more or less, depending on their actual contents.
The ability to set storeUsage to a percent value (similar to its counterpart
percentOfJvmHeap) would help to match the reality closer.
Also, I would like to limit queues to an absolute value, like -eg- 1 GiB, not 3
percent of 70% of a compressible file system, which can mean anything.
