Hi mp,
You have two options to convert a parquet into a delta table through SQL
CONVERT TO DELTA parquet.`/data-pipeline/`
CREATE TABLE events USING DELTA LOCATION '/data-pipeline/'
or
CREATE TABLE events USING PARQUET OPTIONS (path '/data-pipeline/')
CONVERT TO DELTA events
If you want to learn about the differences between the two, there is actually a document on Databricks that explains it in detail

Thank you
