This meant that we also had to bump required memory for the "op-scim-bridge" task definition to 1024 MB. + +The Redis dataset maximum is set to 256Mb and an eviction policy will determine how keys are evicted when the maximum data set size is approached. + +This should prevent Redis from consuming large amounts of memory and eventually running out of available memory. The SCIM bridge is also restarted in instances where Redis runs into an out of memory error. + +### December 2021 changes As of December 2021, [the ALB health check path has changed](https://github.com/1Password/scim-examples/pull/162). If you are updating from a version earlier than 2.3.0, edit your `terraform.tf` file [to use `/app` instead of `/`](https://github.com/1Password/scim-examples/pull/162/commits/a876c46b9812e96f65e42e0441a772566ca32176#) for the health check before reapplying your Terraform settings.
