Your question:
Extract creation is very slow when loading 12 columns/1.5 million rows of data with WebDataConnector3.
・In Fetcher, use fetchJson to read Schema.
・In the Fetcher, use loadParquetData to load data.
The above two processes are quick, but it will take more than 20 minutes when Tableau performs the process of creating the extraction.
When only loading data using loadParquetData without loading Schema, the process of creating an extraction takes about 3 minutes.
The following is my quesiton.
Is it a specification that loading Schema slows down the creation of the extraction?
Is there any possibility to improve the process so that the creation of the extraction will be faster even if Schema is loaded?
