Your VICIdial Database Will Melt Down in 6 Months. Here's How to Prevent It.

It starts the same way every time. Your VICIdial runs fine for six months. Then one Monday morning, agents can't log in. Real-time reports take 30 seconds to load. The hopper drains faster than it fills. CPU is pegged -- not by Asterisk, but by MySQL grinding through a query on a vicidial_log table with 47 million rows because nobody set up archival. The database is VICIdial's single most critical component. Every agent action, call event, disposition, real-time report, hopper query, and dial-level calculation flows through one MySQL instance. In a VICIdial cluster, you can add telephony servers for call capacity and web servers for agent connections. You cannot cluster the database. When it slows down, everything slows down. Why VICIdial's Database Is Different VICIdial's access patterns are unusual and demanding compared to most web applications: High-frequency writes. Multiple Perl daemons update agent states, call statuses, and dial metrics across dozens of tables every second. The
