Hello I have 1 question. Is there any application or open source can query data in Delta lake-house ? And return json data to client application, not using delta-sharing. I found https://github.com/rajagurunath/lakehouse-sharing -> it is official solution for lake-house sharing ?

Hi @Thanhtan Le Thanks for reaching out, If I understand correctly, you are trying to query delta table directly (without using spark) and get the result as json records . In that case , we can use delta-rs package or python variant of delta-rs package to read the delta table as arrow table (or pandas dataframe)and convert the result set into json records of required schema. Delta table ——> delta-rs read —-> arrow table /pandas ——> json records This project (lakehouse sharing) that you have mentioned is implemention of delta-sharing protocol which will give you json records of s3 uri of parquet files .that you need to download and read has pandas dataframe and send it as json . Hope this helps! Some Reference: https://github.com/delta-io/delta-rs https://roapi.github.io/docs/config/dataset-formats/delta.html

tks for your reply. In python package, I did not see authen using adlsg2 ? data file still in local file
