Configure Managed Connection Pooling

MySQL  |  PostgreSQL  |  SQL Server

This page describes how to enable, configure, and monitor Managed Connection Pooling inyour Cloud SQL instances.

Managed Connection Pooling lets you scale your workloads by optimizing resourceutilization and connection latency for your instances using pooling. Fordetailed information about Managed Connection Pooling and how to use it for yourinstances, seeManaged Connection Pooling overview.

Before you begin

Enable Managed Connection Pooling

You can enable Managed Connection Pooling for an instance at time of creation,or edit an existing instance to enable it.

Enable Managed Connection Pooling for a new instance

To create a new instance with Managed Connection Pooling enabled, seeCreate instances. You can enableManaged Connection Pooling for a new instance usinggcloud CLI or theCloud SQL API only.

Enable Managed Connection Pooling for an existing instance

To enable Managed Connection Pooling for an existing instance, do the following:

Console

  1. In the Google Cloud console, go to theCloud SQL Instances page.

    Go to Cloud SQL Instances

  2. Find the instance you want to enable Managed Connection Pooling for.To open the Overview page of the instance, click the instance name.

  3. ClickEdit.

  4. UnderCustomize your instance, expandConnections.

  5. To enable Managed Connection Pooling, check the box forEnable Managed Connection Pool.

  6. ClickSave.

    Note: This will cause your instance to restart.

gcloud

Use thegcloud sql instances command to enable Managed Connection Pooling.

  gcloud sql instances patchINSTANCE_NAME \  --enable-connection-pooling

Replace the following:

  • INSTANCE_NAME: the name of the Cloud SQL instance.

REST v1

Use the following command and setconnectionPoolingEnabled:

Before using any of the request data, make the following replacements:

Monitor Managed Connection Pooling

You canmonitor howManaged Connection Pooling is running on your Cloud SQL instances using thefollowing Cloud SQL Managed Connection Pooling metrics:

Metric nameDescription
threadsTracks the threads count in the connection pool by its status. The statuses included in this metric are:
  • idle: the number of idle threads in the pool.
  • active: the number of active (non-idle) threads in the pool.
pending_connectionThe number of connections actively in the pooling queue.
avg_wait_timeThe average time spent by the connection request waiting for a server.

For more information about these metrics, seeCloud SQL metrics. To view thesemetrics using the Google Cloud console, seeView metrics on the Cloud SQL instance overview page.
