These improvements make Pulsar 4.0's Docker runtime an even more compelling
choice for organizations requiring both security and performance in their
messaging infrastructure. The combination of Alpine Linux's minimal attack
surface and Java 21's advanced garbage collection provides a robust foundation
for running Pulsar in containerized environments.

### Enhanced Quality of Service (QoS) Controls
Multi-tenancy in messaging systems presents unique architectural challenges,
particularly around resource isolation and predictable performance. Apache
Pulsar's approach to this has centered on providing granular control over
system resources while maintaining consistency across tenant workloads.
The core advancement in Pulsar 4.0 comes through [PIP-322 Pulsar Rate Limiting
Refactoring](https://github.com/apache/pulsar/blob/master/pip/pip-322.md). At
its foundation is a token bucket algorithm implementation that unifies rate
limiting across broker, topic, and resource group levels. This eliminates the
previous split between "default" and "precise" rate limiters—a design choice
that had introduced unnecessary CPU overhead and lock contention in IO threads.
-The practical impact is straightforward: more predictable performance in
multi-tenant deployments, especially when multiple rate limiting conditions
intersect. The community is already building on this foundation with
[PIP-385](https://lists.apache.org/thread/9wddmj4o5mrdst427r40rr7phqb05y6s),
which addresses producer flow control — a key piece in completing Pulsar's
end-to-end QoS capabilities.
