-----------------------------------
Summary: camel-core - dynamic EIPs: do not normalize the same
endpoint URI again on every exchange
Key: CAMEL-26899
URL: https://issues.apache.org/jira/browse/CAMEL-26899
Project: Camel
Issue Type: Sub-task
Components: camel-core
Reporter: Claus Ibsen
Fix For: 4.25.0
The dynamic EIPs normalize their endpoint URI on every exchange, even when the
expression gives the same URI every time:
* recipientList, routingSlip and dynamicRouter:
{{ProcessorHelper.prepareRecipient}} calls
{{CamelContextExtension.normalizeUri(uri)}}.
* toD, enrich and wireTap: {{SendDynamicProcessor}} creates a
{{NormalizedUri.newNormalizedUri(uri, false)}}. Enrich always goes through
SendDynamicProcessor, also for a constant URI.
Measured in CAMEL-25132 (on 4.23.0-SNAPSHOT): 49 ns and 216 B for {{mock:x}},
and about 1.3 KB with query parameters.
Idea: a small per-processor cache from the String URI to its normalized form (a
last-hit entry, or a bounded LRU sized like the producer cache). Things to keep:
* The {{allowedSchemes}} check and the placeholder handling must run as today.
CAMEL-25810 changes how placeholders in dynamic URIs are resolved in this same
code: land this after it, and key the cache on the URI as the expression
returned it.
* Bound the cache, as dynamic URIs can be unbounded (one URI per message).
* Add a test that the same endpoint is resolved, and a micro-benchmark or
allocation test showing the gain.
