## Context We need to initiate the Code Embeddings pipeline for `gitlab-org/gitlab` in production. ## References Prior art in `staging`: - https://gitlab.com/gitlab-org/gitlab/-/work_items/554923+ - https://gitlab.com/gitlab-com/gl-infra/production/-/issues/20237+ - https://gitlab.com/gitlab-com/gl-infra/production/-/issues/20258+ - https://gitlab.com/gitlab-org/gitlab/-/work_items/561382+ - https://gitlab.com/gitlab-com/gl-infra/production/-/issues/20347+ ## Proposed steps 1. Ensure that [active_context_code_index_project feature flag](https://gitlab.com/gitlab-org/gitlab/-/issues/556108) is disabled for all projects in production 2. Create and activate the ActiveContext connection 3. Wait for the migration to run, and for the collection record to be created 4. Update the embeddings generation queue throughput 5. Enable [active_context_code_index_project feature flag](https://gitlab.com/gitlab-org/gitlab/-/issues/556108) for `gitlab-org/gitlab` 6. Ensure that the `Ai::ActiveContext::Code::EnabledNamespace` record for `gitlab-org` has `state=pending`. See Change Request: https://gitlab.com/gitlab-com/gl-infra/production/-/issues/20379+
