library. I'm trying to create a Delta table based on a Parquet file. Here's what I'm doing: First, I load the Parquet file using Arrow and extract its schema. I then attempt to create a Delta table, aiming to mirror the Parquet's schema as closely as possible. However, when I attempt to insert the data from the Parquet file into the Delta table, I encounter the following error:
I tried to follow these two texts here: 1, 2, but I'm not able to solve it. I haven't found a straightforward way to create the Delta table directly using the Parquet file. I would greatly appreciate any assistance or pointers on how to resolve this issue. Here is the link to the Stack Overflow question for more details and the code: https://stackoverflow.com/questions/76506007/error-when-trying-to-generate-a-delta-table-from-a-parquet-file-using-delta-rs-l Thank you in advance for your help.
