What Is A Parquet File. Parquet works really well with apache spark. Parquet format is supported for the following connectors:
Parquet is also a better file format in reducing storage costs and speeding up the reading step when it comes to large sets of data. If you are not, here's a quick article reference: We created parquet to make the advantages of compressed, efficient columnar data representation available to any project in the hadoop ecosystem.

The file format is language independent and has a binary representation. In order to understand parquet file format in hadoop better, first let’s see what is columnar format. Apache parquet is a file format designed to support fast data processing for complex data, with several notable characteristics:
It Is A Flat Columnar Storage Format That Is Highly Performant Both In Terms Of.
Many tools and frameworks support this such as hadoop, spark, aws redshift, and databricks platform. Parquet is used to efficiently store large data sets and has the extension.parquet. Columnar storage limits io operations.
Parquet Is Also A Better File Format In Reducing Storage Costs And Speeding Up The Reading Step When It Comes To Large Sets Of Data.
Apache parquet is designed for efficient as well as performant flat columnar storage format of data compared to row based files like csv or tsv files. Columnar storage can fetch specific columns that you need to. For further information, see parquet files.
Azure Data Lake Storage Gen2;
If the data is stored in a csv file, you can read it like this: Parquet is a columnar file format, so pandas can grab the columns relevant for the query and can skip the other columns. Apache parquet is designed to be a common interchange format for both batch and interactive workloads.
Parquet Is A Columnar Format That Is Supported By Many Other Data Processing Systems, Spark Sql Support For Both Reading And Writing Parquet Files That Automatically Preserves The Schema Of The Original Data.
Parquet is a columnar format, supported by many data processing systems. Databricks also provide a new flavour to parquet that allows data versioning and “time travel” with their delta lake format. In fact, it is the default file format for writing and reading data in spark.
