Laravel 9 - How to troubleshoot 'Too many connections' scenarios when using MySQL with long-running processes?
I've hit a wall trying to I'm updating my dependencies and I'm currently working with a 'Too many connections' behavior in my Laravel 9 application when trying to run long-running background jobs that use the database extensively... I've configured my database connection using MySQL, and while running migration and seeding tasks, this behavior pops up intermittently, especially when the queue worker processes multiple jobs concurrently. My current database settings are: ```php 'mysql' => [ 'driver' => 'mysql', 'host' => env('DB_HOST', '127.0.0.1'), 'port' => env('DB_PORT', '3306'), 'database' => env('DB_DATABASE', 'forge'), 'username' => env('DB_USERNAME', 'forge'), 'password' => env('DB_PASSWORD', ''), 'unix_socket' => env('DB_SOCKET', ''), 'charset' => 'utf8mb4', 'collation' => 'utf8mb4_unicode_ci', 'prefix' => '', 'strict' => true, 'engine' => null, ], ``` I've also checked the `max_connections` setting in my MySQL configuration, which is set to 100, but when I monitor the processes in MySQL, I sometimes see the connections peaking around this limit. My application logic involves multiple jobs performing heavy database operations, and I worry that this might be contributing to the scenario. To mitigate this, I've tried increasing the `DB_CONNECTIONS` limit in my `.env` file, but this doesn't seem to resolve the scenario. I've also considered implementing a connection pooling mechanism or optimizing my queries, but I'm not sure where to start. Does anyone have suggestions on how to handle this situation effectively? Should I be looking at optimizing job processing, or is there a better approach to managing MySQL connections in Laravel? Any insights would be greatly appreciated! I'm coming from a different tech stack and learning Php. Thanks for your help in advance! This is for a web app running on Windows 11.
