Is there anyone using DigitalOcean having/not having such issues? Any clues what else I can do? We've tried database configuration with pgbouncer and without pgbouncer (seems to be better), decreased maxLifetime to 60000, made sure we have enough connections available to the managed database (only about 20 from 47 are used) but the issue still appears. From time to time we get errors 500 from FA and then in the FA logs we can see that the problem is caused by the closed database connections (full traceback below). The script uses values from vpc-with-pg's output.json to configure the stacks context environment and variables.We're using FA with a managed PostgreSQL instance on DigitalOcean. Use the deploy script to deploy the CDK solution. The resolver uses your provided username/role to run queries. The provider uses the postgres role for configuration. See this AWS post for more details on security best practices for Amazon RDS for PostgreSQL. This role should have the scoped-down privileges required to access the schema(s). username/role to use to execute queries.schema(s) of interest (containing our tables and functions).You will also need to know the following information about our Postgres database: this security group must be an allowed source of traffic for your RDS Proxy security group.
at least one private subnet with a NAT that your AWS Lambda function ENIs will be deployed into, and a VPC Security Group. and securely store credentials in AWS Secrets Manager. we use AWS Identity and Access Management (IAM) authentication for databases. an RDS Proxy associated with our RDS Postgres database. To get started, you need the following to enable connections to our database:

RequirementsĬlone this repository and install dependencies:ĭeploy the solution into an existing vpc with RDS, or after deploying vpc-with-pg.
The Lambda function resolves the query using the PostGraphile schema and RDS databaseįor more information about the solution and a detailed walk-through, please see the related blog. The identity of the user is included in the request to the resolver Lambda function AppSync resolves the request by calling the attached Direct Lambda Resolver. AppSync authorizes the request using the configured Authorization Mode (API KEY, Cognito User Pool, etc.). The AppSync API is now ready to process requests. #Aws postgresql timed out update#
Note that a user can repeat step 1 at any time (e.g.: after a database schema change) to update the AppSync API definition. It updates the schema, and properly sets up the queries, mutations, and subscriptions. The provider updates the Layer function attached to the resolver Lambda function and updates the AppSync API.
The provider function retrieves schema information from RDS database using Postgaphile. Once the solution is deployed, a user runs the provider function to analyze the RDS PostgreSQL database and generate the GraphQL schema. The solution creates an AppSync API with a datasource that uses the resolver Lambda function, and an AppSync function that uses that datasource. Start by deploying the CDK-based solution. Updating after a database schema change. 
Serverless auto-generated GraphQL API with AWS AppSync and PostGraphile. It uses the AWS CDK, does not require writing any code, supports subscriptions, and works with any PostgreSQL database like Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL. The solution is serverless, and can be deployed in a few clicks. This solution leverages PostGraphile to automatically generate an AppSync compliant schema from PostgreSQL tables, and uses Lambda functions to resolve GraphQL queries against a PostgreSQL database in Amazon RDS. See this blog post for additional information. This repo provides a CDK-based solution that allows you to create an AWS AppSync API from a defined Postgres database in AWS RDS.
