Loading Parquet files into Visplore

Files in the Apache Parquet format are becoming increasingly popular for compactly storing large amounts of data. 

Good news: there is a new way to import time series data directly from Parquet files into Visplore!

For this purpose, we have developed a Custom Data Connector – a Visplore plugin written in Python that can be easily added to the current Visplore version.

In addition to loading a Parquet file, the new Parquet connector also allows the user to select variables and optionally define a time rasterization (e.g. one value per minute). This makes even extensive time series data manageable. We are glad about the very positive feedback from our customers! 

-> If you are interested in the Parquet Connector, we are happy to provide it free of charge upon request!

Please send an email to support@visplore.com.

The following video shows the application:

As described, this is a Visplore plugin written in Python. Similarly, other file formats or data sources can be supported for direct import into Visplore. We are happy to provide customers with the Parquet connector’s source code as an example of how to connect their own data sources.

Final note: in the next release (plan: second quarter 2023), Parquet files will be supported by an integrated import option.
