Use delta lake data

[MammadTavakoli]

I use delta lake for create datalake for my data. how can I use gparhAr for processing delta lake data?

[SemyonSinchenko]

Delta tables are parquet files + metadata layer on top of them. GraphAr share the same idea: parquet files and metadata on top of them. But these metadata layers are not compatible between each other. Could you please describe your usecase? Why you want to store GAR data in delta instead of parquet or orc?

If you have a Databricks you can use GraphX / GraphFrames to read data from delta tables, and after that you can use GAR Spark to save your graphs to your cloud delta lake. I think you can register GAR graphs as Volumes in Databricks Unity Catalog but I'm not 100% sure.
