The site slows down at peak
During sales or ad launches the main database cannot keep up with the number of requests.
Redis
A key-value data store that runs in memory. We choose it when the main database cannot keep up with requests and the delay is noticeable to customers.
WHY WE CHOOSE THIS
When every request goes to the main database, the site slows down right at peak time. Redis serves frequent data from memory in milliseconds, and the main database stops being a bottleneck.
Many background tasks
Emails, notifications, document generation or syncs need to run in a queue without blocking the user.
Real-time features
Counters, rankings, rate limits or online statuses need to update instantly.
Page and API caching
Frequent responses are kept in memory, so the catalog and API respond without hitting the database.
Sessions and carts
Storage of user sessions and carts with automatic key expiry.
Background job queues
Redis-based queues, such as BullMQ, for emails, imports and integrations.
Counters and limits
Atomic operations for rate limits, rankings and real-time statistics.

Other technologies in our stack
Does Redis replace the main database?+
No. Redis complements PostgreSQL or MySQL: it holds fast data such as cache, sessions and queues, while orders, customers and payments stay in the main database, where integrity matters more than speed.
Will we lose data if Redis restarts?+
It depends on the configuration. The cache rebuilds itself, and for sessions and queues we enable disk persistence and replication. We never keep critical business data in Redis as the only source.
Why Redis and not Memcached?+
It depends on the task. Both work for a simple cache. We choose Redis more often because beyond caching it offers queues, data structures, disk persistence and replication, so one tool covers several needs.
Response speed is part of the customer experience.
Redis development at GVSPACE means speeding up websites, stores and apps that have to handle traffic peaks. We set up page and API caching, session and cart storage, background job queues and real-time counters. Redis works alongside PostgreSQL or MySQL and takes repeated queries off the main database, so the product responds fast even on a sale day.
