DQ-INDEXD(1)

💖 DQ-INDEXD — the index server for IPC::DirQueue tasks 💖

okay bestie, sit down, hydrate, and let me tell you about dq-indexd — it's a User Contributed Perl Documentation situation, page DQ-INDEXD(1), and it is lowkey the little daemon that keeps your queue vibes organised. 🫶

---

✨ SYNOPSIS ✨

dq-indexd --port port

that's it. that's the whole invocation. iconic. 💅

---

🌸 DESCRIPTION 🌸

okay so dq-indexd is a single-process, event-driven daemon — yes, single process, she's doing it all herself, main character energy only — and IPC::DirQueue uses her to track queue activity at a centralised point. ✨

here's the tea: IPC::DirQueue keeps its queue files in a filesystem directory, and normally it just uses the normal UNIX filesystem readdir APIs to list the queue. classic, reliable, we love her. 💖

but — and this is the plot twist 🎀 — in certain situations when NFS is in use, those APIs may scale poorly. like, not great, not slay. so a TCP/IP-based central server may be more appropriate. 🦋

⚠️ real talk though: going the central-server route adds a new single point of failure. she's cute but she's a bottleneck, no cap. 😭

and that is exactly what dq-indexd makes possible. periodt. 👑

and that's the whole page, gorgeous. this lil masterpiece is from perl v5.42.0, dated 2025-07-25, and it lives at DQ-INDEXD(1) under User Contributed Perl Documentation. 🎀 go forth, run your index server, and stay hydrated. mwah. 💜🦋✨
