Simplify Table Merge Operations with Delta Lake

Simplify Table Merge Operations with Delta Lake

Merging two datasets and performing both insert and update operations can be a complex task. Delta Lake makes it easy to perform multiple data manipulation operations during a merge operation.

The following code demonstrates merging two datasets using Delta Lake:

✔️ If a match is found, the last_talk value in people_table is updated with the corresponding value from new_df 

✖️ If a match is not found and the last_talk value in people_table is older than 30 days, the status column is updated to ‘rejected’.

Full code.
