What is Postgres

An object-relational database management system, PostgreSQL is able to handle a wide range of workloads, supports multiple standards, and is cross-platform, running on numerous operating systems including Microsoft Windows, Solaris, Linux, and FreeBSD. It is highly extensible, and supports more than 12 procedural languages, Spatial data support, Gin and GIST Indexes, and more. Many webs, mobile, and analytics applications use PostgreSQL as the primary data warehouse or data store.

What is TiDB

TiDB is a distributed SQL database that is designed to handle large-scale online transaction processing (OLTP) and online analytical processing (OLAP) workloads. It is an open-source, cloud-native database that is built to be highly available, scalable, and fault-tolerant. TiDB uses a distributed architecture that allows it to scale horizontally across multiple nodes, while also providing strong consistency guarantees. It supports SQL and offers compatibility with MySQL, which makes it easy for developers to migrate their existing applications to TiDB. TiDB is used by companies such as Didi Chuxing, Mobike, and Meituan-Dianping to power their mission-critical applications.

Prerequisites

A Postgres account to transfer your customer data automatically from.
A TiDB account.
An active Airbyte Cloud account, or you can also choose to use Airbyte Open Source locally. You can follow the instructions to set up Airbyte on your system using docker-compose.

Airbyte is an open-source data integration platform that consolidates and streamlines the process of extracting and loading data from multiple data sources to data warehouses. It offers pre-built connectors, including Postgres and TiDB, for seamless data migration.

When using Airbyte to move data from Postgres to TiDB, it extracts data from Postgres using the source connector, converts it into a format TiDB can ingest using the provided schema, and then loads it into TiDB via the destination connector. This allows businesses to leverage their Postgres data for advanced analytics and insights within TiDB, simplifying the ETL process and saving significant time and resources.

Step 1: Set up Postgres as a source connector

1. Open your PostgreSQL database and create a new user with the necessary permissions to access the data you want to replicate.

2. Obtain the hostname or IP address of your PostgreSQL server and the port number it is listening on.

3. Create a new database in PostgreSQL that will be used to store the replicated data.

4. Obtain the name of the database you just created.

5. In Airbyte, navigate to the PostgreSQL source connector and click on "Create Connection".

6. Enter a name for your connection and fill in the required fields, including the hostname or IP address, port number, database name, username, and password.

7. Test the connection to ensure that Airbyte can successfully connect to your PostgreSQL database.

8. Select the tables or views you want to replicate and configure any necessary settings, such as the replication frequency and the replication method.

9. Save your configuration and start the replication process.

10. Monitor the replication process to ensure that it is running smoothly and troubleshoot any issues that arise.

Step 2: Set up TiDB as a destination connector

1. First, navigate to the Airbyte website and log in to your account.
2. Once you are logged in, click on the "Destinations" tab on the left-hand side of the screen.
3. Scroll down until you find the TiDB destination connector and click on it.
4. You will be prompted to enter your TiDB database credentials, including the host, port, username, and password.
5. Once you have entered your credentials, click on the "Test" button to ensure that the connection is successful.
6. If the test is successful, click on the "Save" button to save your TiDB destination connector settings.
7. You can now use the TiDB destination connector to transfer data from your source connectors to your TiDB database.
8. To set up a data integration pipeline, navigate to the "Connections" tab on the left-hand side of the screen and create a new connection.
9. Select your TiDB destination connector as the destination and choose your source connector as the source.
10. Configure the settings for your data integration pipeline, including the frequency of data transfers and any data transformations that you want to apply.
11. Once you have configured your data integration pipeline, click on the "Save" button to save your settings.
12. Your data integration pipeline will now run automatically, transferring data from your source connectors to your TiDB database on a regular basis.

Step 3: Set up a connection to sync your Postgres data to TiDB

Once you've successfully connected Postgres as a data source and TiDB as a destination in Airbyte, you can set up a data pipeline between them with the following steps:

Create a new connection: On the Airbyte dashboard, navigate to the 'Connections' tab and click the '+ New Connection' button.
Choose your source: Select Postgres from the dropdown list of your configured sources.
Select your destination: Choose TiDB from the dropdown list of your configured destinations.
Configure your sync: Define the frequency of your data syncs based on your business needs. Airbyte allows both manual and automatic scheduling for your data refreshes.
Select the data to sync: Choose the specific Postgres objects you want to import data from towards TiDB. You can sync all data or select specific tables and fields.
Select the sync mode for your streams: Choose between full refreshes or incremental syncs (with deduplication if you want), and this for all streams or at the stream level. Incremental is only available for streams that have a primary cursor.
Test your connection: Click the 'Test Connection' button to make sure that your setup works. If the connection test is successful, save your configuration.
Start the sync: If the test passes, click 'Set Up Connection'. Airbyte will start moving data from Postgres to TiDB according to your settings.

Remember, Airbyte keeps your data in sync at the frequency you determine, ensuring your TiDB data warehouse is always up-to-date with your Postgres data.

Use Cases to transfer your Postgres data to TiDB

Integrating data from Postgres to TiDB provides several benefits. Here are a few use cases:

Advanced Analytics: TiDB’s powerful data processing capabilities enable you to perform complex queries and data analysis on your Postgres data, extracting insights that wouldn't be possible within Postgres alone.
Data Consolidation: If you're using multiple other sources along with Postgres, syncing to TiDB allows you to centralize your data for a holistic view of your operations, and to set up a change data capture process so you never have any discrepancies in your data again.
Historical Data Analysis: Postgres has limits on historical data. Syncing data to TiDB allows for long-term data retention and analysis of historical trends over time.
Data Security and Compliance: TiDB provides robust data security features. Syncing Postgres data to TiDB ensures your data is secured and allows for advanced data governance and compliance management.
Scalability: TiDB can handle large volumes of data without affecting performance, providing an ideal solution for growing businesses with expanding Postgres data.
Data Science and Machine Learning: By having Postgres data in TiDB, you can apply machine learning models to your data for predictive analytics, customer segmentation, and more.
Reporting and Visualization: While Postgres provides reporting tools, data visualization tools like Tableau, PowerBI, Looker (Google Data Studio) can connect to TiDB, providing more advanced business intelligence options. If you have a Postgres table that needs to be converted to a TiDB table, Airbyte can do that automatically.

FAQs

What is ETL?

ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.

What is Postgres?

What data can you extract from Postgres?

PostgreSQL gives access to a wide range of data types, including:

1. Numeric data types: This includes integers, floating-point numbers, and decimal numbers.

2. Character data types: This includes strings, text, and character arrays.

3. Date and time data types: This includes dates, times, and timestamps.

4. Boolean data types: This includes true/false values.

5. Network address data types: This includes IP addresses and MAC addresses.

6. Geometric data types: This includes points, lines, and polygons.

7. Array data types: This includes arrays of any of the above data types.

8. JSON and JSONB data types: This includes JSON objects and arrays.

9. XML data types: This includes XML documents.

10. Composite data types: This includes user-defined data types that can contain multiple fields of different data types.

Overall, PostgreSQL's API provides access to a wide range of data types, making it a versatile and powerful tool for data management and analysis.

How do I transfer data from Postgres?

This can be done by building a data pipeline manually, usually a Python script (you can leverage a tool as Apache Airflow for this). This process can take more than a full week of development. Or it can be done in minutes on Airbyte in three easy steps:
1. Set up PostgreSQL to TiDB as a source connector (using Auth, or usually an API key)
2. Choose a destination (more than 50 available destination databases, data warehouses or lakes) to sync data too and set it up as a destination connector
3. Define which data you want to transfer from PostgreSQL to TiDB and how frequently
You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.

What is ELT?

ELT, standing for Extract, Load, Transform, is a modern take on the traditional ETL data integration process. In ELT, data is first extracted from various sources, loaded directly into a data warehouse, and then transformed. This approach enhances data processing speed, analytical flexibility and autonomy.

Difference between ETL and ELT?

ETL and ELT are critical data integration strategies with key differences. ETL (Extract, Transform, Load) transforms data before loading, ideal for structured data. In contrast, ELT (Extract, Load, Transform) loads data before transformation, perfect for processing large, diverse data sets in modern data warehouses. ELT is becoming the new standard as it offers a lot more flexibility and autonomy to data analysts.
