As a data-driven business, extracting meaningful data from various sources and making informed decisions relies heavily on effective data analysis. To unlock the full potential of your data in PostgreSQL on Google Cloud SQL necessitates data integration with Amazon Aurora. This migration offers several advantages, such as enhanced data processing speed and availability, enabling data-driven decision-making through analytics.

Migrating data from Google Cloud PostgreSQL to Amazon Aurora is an essential step in optimizing your database ecosystem. This migration offers several advantages, such as improved performance, scalability, and availability, ensuring your data infrastructure can meet the growing analytics demands.

Methods to Connect PostgreSQL on Google Cloud SQL to Amazon Aurora

In this guide, you’ll discover two different methods to connect PostgreSQL on Google Cloud SQL to Amazon Aurora. The initial approach involves manual loading, whereas the second method automates the entire migration process.

Let’s get started!

Method 1: Manually Load Data from PostgreSQL on Google Cloud SQL to Amazon Aurora

Manually transferring data from Google Cloud SQL PostgreSQL to Aurora involves several steps. 

Here’s a detailed, step-by-step guide:

Step 1: Export Data from Google Cloud SQL PostgreSQL

You can use the pg_dump utility command to export data from PostgreSQL hosted on Google Cloud SQL. This command is specifically used for backing up a PostgreSQL database. 

If you want to export a single PostgreSQL database, use the pg_dump utility. For exporting all PostgreSQL databases within a cluster, use the pg_dumpall utility command.

  • Open the command prompt on your local machine or server that has access to the Google Cloud SQL and execute the following command:
pg_dump -h <Cloud_SQL_Hostname> -U <Username> -d <Database_Name> -t <table_name> -f <path_to_output_File.sql>

Replace <Cloud_SQL_Hostname>, <Username>, and <Database_Name> with your database information. If you want to export a specific table, include the – t flag and specify the table name in this <table_name> field. Provide the name and path for the output file where the data will be stored.

  • Provide the password when prompted for your Google Cloud PostgreSQL user.
  • The data will be stored in a specific output in the SQL format on your local machine. This file will contain SQL statements that can be used to recreate or replicate a database schema, its tables, data, and other related database objects.

Step 2: Set up Amazon Aurora

  • Log into your AWS Management Console.
  • Go to the Amazon Aurora service.
  • Aurora provides support for both MySQL and PostgreSQL database engines. In this guide, we will proceed with the PostgreSQL-compatible database. You can choose the existing instance or click Create Database to create a new Amazon Aurora Instance. 
  • If you create a new instance, select the edition of your Aurora database, configure the network settings, and set the credentials. Click on Create Database.

Step 3: Import Data to Amazon Aurora

  • Now, we will copy the dump (.sql file) to the server where your Aurora instance is accessible.
  • Use the psql to import the data into your Amazon Aurora PostgreSQL database in the command prompt.
psql -h <Aurora_Hostname> -U <Username> -d <Database_Name> -f <file.sql>

Replace the <Aurora_Hostname>, <Username>, and <Database_Name> with your Aurora database details. <file.sql> with the name and path to .sql output file.

However, if you choose the Aurora MySQL database, you can use the mysql command to import the .sql file data into the Aurora MySQL-compatible database.

The manual approach to replicate data from PostgreSQL on Google Cloud SQL to Amazon Aurora is suitable for several use cases:

  • Occasional Transfers: The above approach is suitable for infrequent backups and small datasets. It doesn’t require a complex data pipeline setup, making it quick and straightforward.
  • Control and Flexibility: When you migrate data manually, you have full control over each step of the transfer process. You can make granular decisions about what data to migrate, how to handle exceptions, and how to ensure data consistency and integrity. In addition to this, if the PostgreSQL database undergoes changes that impact the migration, manual migration allows you to adapt quickly. You are not restrained to pre-defined migration scripts.

However, there are a few limitations of manually migrating data from PostgreSQL on Google Cloud SQL to Amazon Aurora:

  • Limited Real-time Sync: As this approach is specifically for one-time transfers, it cannot support real-time workflows. This can restrict you from achieving timely insights as your target database may not reflect the most up-to-date information.
  • Complexity and Risks: Manual migrations for moving data from PostgreSQL hosted on Google Cloud can be complex when dealing with large datasets. For instance, when migrating a customer database, mismatches in key constraints can result in data integrity issues. This will impact order processing and customer experiences. To mitigate these risks, careful planning, testing, and validation processes are important during manual migrations.

Method 2: Using a No-Code Tool like Hevo Data to Build PostgreSQL on Google Cloud SQL to Amazon Aurora ETL Pipeline

Using a no-code tool for PostgreSQL on Google Cloud SQL to Amazon Aurora data migration can be a reliable alternative. It offers several benefits like:

  • Scalability: No-code tools are designed with the capability to handle both small and extensive datasets. This scalability eliminates the need for manual adjustments as your data volume increases.
  • Efficiency: No-code tools automate several tasks involved in data migration, reducing the time and effort required in the process. These tasks include data extraction, data loading, schema mapping, error handling, incremental updates, and more. This efficiency allows you to complete the replication process more quickly and with fewer errors.

Hevo Data is a robust no-code platform known for its scalability in data integration. With its 150+ pre-built connectors, you can seamlessly integrate Google Cloud SQL PostgreSQL to Amazon Aurora. This allows you to achieve the migration process even without requiring technical resources or expertise.
