Under The Hood And On The Surface Of Sidekiq — Paweł Dąbrowski at wroclove.rb 2022

Paweł Dąbrowski walks through Sidekiq best practices (naming, simple params, small jobs, connection pooling, prepend modules over inheritance, smart retry/logging) and then dives into Sidekiq internals — how jobs are pushed to and pulled from Redis, the poller/manager split, and the role of middleware. Q&A covers the Sidekiq 7 transaction-commit fix, wrappers vs inline logic, handling large ID lists with batches, Redis cluster support, scaling, and application-level back pressure.
