Supabase Database Query canceled due to user request or timeout.

What is Supabase Database Query canceled due to user request or timeout.

Understanding Supabase Database

Supabase is an open-source backend-as-a-service platform that provides developers with a suite of tools to build applications quickly. It includes a PostgreSQL database, authentication, storage, and real-time subscriptions. Supabase aims to simplify the development process by offering a scalable and easy-to-use backend solution.

Identifying the Symptom

When working with Supabase Database, you might encounter an error message with the code 57014. This error indicates that a query was canceled, either due to a user request or because it exceeded the allowed execution time. The symptom is typically observed when a query does not complete as expected and returns an error message.

Explaining the Issue

Error Code 57014

The error code 57014 is a PostgreSQL error that signifies a query cancellation. This can happen for two main reasons: either the user manually canceled the query, or the query took too long to execute and was automatically terminated by the system. In Supabase, this is often related to performance issues or misconfigured timeout settings.

Steps to Fix the Issue

Optimize Your Query

To resolve this issue, start by optimizing your query. Ensure that your SQL queries are efficient and make use of indexes where appropriate. You can use the EXPLAIN command to analyze the execution plan of your query and identify potential bottlenecks.

EXPLAIN ANALYZE SELECT * FROM your_table WHERE condition;

Increase Timeout Settings

If the query is optimized but still timing out, consider increasing the timeout settings. In Supabase, you can adjust the statement timeout by setting the statement_timeout parameter. This can be done by executing the following command:

SET statement_timeout = '60000'; -- sets timeout to 60 seconds

Make sure to set a reasonable timeout value that balances performance and resource usage.
