# Sidekiq job size limits **(FREE SELF)**
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/68982) in GitLab 14.3.
[Sidekiq](../../../administration/sidekiq.md) jobs get stored in
Redis. To avoid excessive memory for Redis, we:
- Compress job arguments before storing them in Redis.
- Reject jobs that exceed the specified threshold limit after compression.
| Limiting mode | Compress | This mode compresses the jobs at the specified threshold and rejects them if they exceed the specified limit after compression. |
| Sidekiq job compression threshold (bytes) | 100 000 (100 KB) | When the size of arguments exceeds this threshold, they are compressed before being stored in Redis. |
| Sidekiq job size limit (bytes) | 0 | The jobs exceeding this size after compression are rejected. This avoids excessive memory usage in Redis leading to instability. Setting it to 0 prevents rejecting jobs. |
