How To Convert Parquet Files into GeoJson Files and Save it in Data Lake using Synapse Notebooks
Introduction
In this article, we will explore how to use Synapse Notebooks to convert Parquet files into GeoJson files and save them in Data Lake. We will use the powerful capabilities of Azure Synapse Analytics to transform data from one format to another and push it into the Data Lake.
Background
Parquet files are a popular format for storing tabular data in HDFS (Hadoop Distributed File System). They are often used for data analysis and machine learning workloads. However, sometimes it is necessary to convert the data into other formats, such as GeoJson.
GeoJson is a standard format for encoding geographic data and is often used for web mapping applications. It is an open standard format that can be used to store and exchange geographic data.
Solution Overview
The first step is to create a Synapse Notebook in Azure Synapse Analytics. This notebook can be used to transform the data from Parquet to GeoJson.
Once the notebook is created, the next step is to upload the Parquet file to the Data Lake. This can be done using the Azure Data Factory.
The next step is to create a PySpark script to transform the Parquet file into GeoJson. This script will be executed in the Synapse Notebook.
The script will read the Parquet file from the Data Lake and convert it into GeoJson format. Once the transformation is complete, the GeoJson file will be stored back in the Data Lake.
Conclusion
In this article, we explored how to use Synapse Notebooks to convert Parquet files into GeoJson files and save them in Data Lake. We used the powerful capabilities of Azure Synapse Analytics to transform data from one format to another and push it into the Data Lake.
The process is relatively straightforward and can be used to quickly transform data from one format to another. This can be a useful tool for data scientists, analysts, and engineers who need to work with different types of data.
With the right tools and resources, transforming data from one format to another can be a relatively simple process. The Azure Synapse Analytics platform makes it easy to quickly and efficiently convert data from one format to another.
