Write PostgreSQL Data to Delta Tables with SQL

This guide outlines the process of using GlareDB to efficiently archive PostgreSQL transaction data to Delta tables, enhancing analytics capabilities without burdening the transactional database. Delta tables, known for supporting ACID transactions, schema evolution, and time travel, are ideal for data lakes. The guide details three key steps: creating a Delta table from PostgreSQL data, adding it as an external table in GlareDB, and inserting new data into the Delta table. This approach not only ensures seamless data archiving but also facilitates easy access to historical data, allowing for improved analytics and reduced database load. The flexibility of GlareDB allows users to apply these techniques across various data sources and storage locations, including local storage, S3, and GCS, making it a scalable solution for different data management needs.
