Deleting data from the Phoenix UI may not immediately free up database space, as deleted records can still occupy disk space until PostgreSQL autovacuum runs. This can cause the database to remain over the size limit, resulting in the "REST API is disabled for writes" error even after clearing your project data. You may need to wait for autovacuum or manually trigger it to reclaim space, or contact support if the issue persists. See details in <https://github.com/Arize-ai/phoenix/issues/6625|this issue> and <https://arize-ai.slack.com/archives/C04R3GXC8HK/p1738187659.759579|Slack discussion>.
Would you like more detail on how to manually reclaim space or check database usage?
