Authenticating an AWS AppSync GraphQL API with Auth0

In this tutorial, the author will walk through how to implement OIDC authentication for your AWS AppSync endpoint using Auth0 as the authentication provider.

“LOCK TABLE” can harm your database’s health

To avoid the problem:

• Don’t use LOCK on a routine basis. Once a day for the nightly bulk load is fine, as long as autovacuum has enough time to finish during the day.
• Tune autovacuum to run more aggressively and hence faster. This can be done by increasing autovacuum_vacuum_cost_limit and reducing autovacuum_vacuum_cost_delay.
• Use PostgreSQL 9.6 or later. Anti-wraparound autovacuum has been improved in 9.6; it now skips pages with only frozen rows to speed up processing.
