Steps
Assign each job a group id, such as a per-tenant identifier, so BullMQ can track and rate-limit groups independently within the same queue.
Configure the worker's rate limiter with a max job count and duration to bound how fast jobs in any one group are processed.
When a group exceeds its rate limit, confirm BullMQ stops processing that group's jobs until the limit window expires while continuing to process other groups' jobs normally.
Use local per-group overrides where specific groups, such as higher-tier tenants, need a different limit than the global default.
Monitor group-level throughput to confirm no single noisy tenant starves the others sharing the worker pool.
Known gotchas
Group rate limiting and local per-group overrides are BullMQ Pro features in the current documentation structure; verify your BullMQ tier supports them before designing multi-tenant throttling around them.
A rate-limited group's jobs simply wait rather than fail, so a persistently over-quota group can build an ever-growing backlog if the limit is set too low for its real traffic.
