Cloud SQL for MySQL

The following steps describe how to enable index advisor for Cloud SQL for MySQL. Index advisor for Cloud SQL for MySQL uses data from MySQL Performance Schema. By default, Cloud SQL enables MySQL Performance Schema on all MySQL 8.0 instances that have more than 15 GB of memory.

1. Before you enable index advisor, enable Query Insights on the instance.
2. If you already have MySQL Performance Schema enabled on your Cloud SQL for MySQL instances, then to enable index advisor, run the following gcloud CLI command:

gcloud sql instances patch INSTANCE_NAME \
    --database-flags=cloudsql_index_advisor=on

Replace INSTANCE_NAME with the name of your instance.

3. If you don't have MySQL Performance Schema enabled on your Cloud SQL for MySQL instances, then to enable index advisor, run the following gcloud CLI command:

gcloud sql instances patch INSTANCE_NAME \
   --database-flags=cloudsql_index_advisor=on,performance_schema=on

Replace INSTANCE_NAME with the name of your instance.

Caution: Setting the performance_schema flag to on restarts your instance automatically.

For more information about configuring flags, see Configure database flags.

Cloud SQL for PostgreSQL

The following steps describe how to enable index advisor for Cloud SQL for PostgreSQL.

1. Before you enable index advisor, enable Query Insights on the instance.
2. To enable index advisor for Cloud SQL for PostgreSQL instances, run the following Google Cloud CLI command:

gcloud sql instances patch INSTANCE_NAME \
   --database-flags=cloudsql.enable_index_advisor=on
    

Replace INSTANCE_NAME with the name of your instance.
