> camel-cli-connector - answer actions in about 100 ms instead of once a second

> Key: CAMEL-25447
> URL: https://issues.apache.org/jira/browse/CAMEL-25447
> Project: Camel
> Issue Type: Improvement
> Components: camel-jbang
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.24.0

>
> The file transport of camel-cli-connector looks for action files once per
> loop, and the loop runs every second (fixed delay 1000 ms) after writing the
> status file. So every action to a running integration waits up to a second
> before the integration sees it, whatever the client: camel get / camel cmd,
> the camel-jbang monitor, the MCP server, camel ask.
> Measured (CAMEL-25438): an action takes about 1 s whatever its size
> (thread-dump, bean, startup-recorder, type-converters of 41 KB); the status
> file is rewritten every ~1015 ms.
> Proposal: check for action files on a schedule of its own, about every 100
> ms, on the same single connector thread, and keep the status file (and the
> trace task) at its current interval. Debug mode already runs the whole loop
> at 100 ms.
> * Cost: a scan of ~/.camel for <pid>-action*.json, about 0.04 ms with 127
> files there: negligible at 10 per second. No extra thread, no TCP port
> (unlike the websocket transport).
> * Gain: an action drops from ~1 s to ~0.1 s for every client.
> * Care: the connector runs inside every integration that has it (Camel Main,
> Spring Boot, Quarkus), so this is a runtime change. A slow action (jfr, up to
> 30 s) still holds up the loop, as today.
