Parquet is built to optimize analytical functions on large datasets containing sophisticated info. It supports highly effective data compression strategies, schema evolution, encoding techniques, and other functionalities that may increase analytical querying.
Apache Parquet supports schema evolution so engineers can certainly take care of changing facts schemas within their workflows. They might incorporate, get rid of, or modify columns in Parquet files without having to rewrite your complete dataset.
Parquet’s functions and Positive aspects help it become a beneficial element in present day facts engineering pipelines. Here are some genuine-earth examples of how Parquet is utilized:
This could make ORC handy in scenarios in which you have numerous columns while in the dataset, and a must obtain only certain subsets of information.
Apache Parquet is only one of many information file formats. In this article’s a comparison of Parquet with other popular facts formats:
When you’re working with pretty huge quantities of information. Parquet is created for performance and powerful compression. Various benchmarking tests that have when compared processing situations for SQL queries on Parquet vs formats such as Avro or CSV (including the a single described in this post, and also this a person), have discovered that querying Parquet brings about significantly speedier queries.
Since it was 1st released in 2013, Apache Parquet has witnessed popular adoption as a cost-free and open up-resource storage structure for quickly analytical querying.
