You've gone full bot mode! Let me fetch that AI answer for you ASAP.
Based on the information provided in the knowledge sources, I can offer some insights and suggestions regarding your issue with idle connections in Prisma when using Supabase's free tier.
1. Supabase Free Tier Limitations:
As mentioned in the Supabase documentation, free tier projects may be paused after 7 days of inactivity to save server resources. This could be contributing to your connection issues.
2. Connection Management:
Prisma's connection pooling behavior is designed to keep connections open for reuse, which is generally efficient but can lead to idle connections. In serverless or auto-scaling environments like Supabase, this can sometimes cause issues.
3. Potential Solutions:
a. Use PgBouncer:
Consider using PgBouncer, which can help manage connection pooling more efficiently. Prisma supports PgBouncer, as documented in their connection management guide.
b. Adjust Connection Limit:
You can try adding
?connection_limit=20&pool_timeout=50 to your database URL, based on your maximum pool connection. This was suggested as a potential fix in a GitHub issue discussion.
c. Manually Disconnect:
Although not ideal, you could try manually disconnecting after each query. However, this approach may lead to "Closed By Other Side" errors, as mentioned in the same GitHub discussion.
d. Use Prisma's Metrics Feature:
Enable Prisma's metrics feature to monitor connection usage. This can help you identify patterns and optimize your connection management. You can find more information about this in the Prisma metrics documentation.
4. NestJS-specific Considerations:
Ensure that you're properly managing the Prisma client lifecycle
in your NestJS application. The onModuleInit and onModuleDestroy hooks you mentioned are a good start, but make sure they're implemented correctly.
5. Consider Upgrading:
If possible, consider upgrading from the Supabase free tier to a paid plan. This could provide more stable and consistent database access, potentially resolving some of your connection issues.
Remember, the root cause of your specific issue might require further investigation. If these suggestions don't resolve your problem, you may want to open a detailed issue on the Prisma GitHub repository with your specific setup and error logs for more tailored assistance.Hi @hari_narayan
