What Is Zero Copy in Data? (and How It Works)

Zero Copy Integration is a method of accessing and utilizing data from multiple databases without the need to move, copy, or reformat that data. It eliminates the need for traditional data duplication processes like extract-transform-load (ETL), streamlining access to large datasets across various platforms and systems.

By avoiding the transfer and transformation of data, Zero Copy Integration improves efficiency, reduces the risk of errors, and saves on costs.

Traditional Data Copying vs. Zero Copy Integration

In traditional data management systems, copying data from one database to another is common, particularly in large organizations where data is spread across different locations and systems. This often involves the following steps:

1. Extract: Pull data from one or more source systems.
2. Transform: Reformat or clean the data so it fits the requirements of the target system.
3. Load: Copy the transformed data into the target system for further use.

This extract-transform-load (ETL) process is effective, but it comes with challenges:

• Time-consuming: ETL processes take time to complete, especially when dealing with massive datasets.
• Resource-intensive: It uses significant computational and storage resources.
• Error-prone: Each step introduces the potential for data loss or…
