Types of Heterogeneous Data Sources

[CoiChedid]

Hello all,

I'm very interested in the capabilities of SemaGrow, but I'm with a really simple doubt.

I read all available documentation, but I can't understand what do you mean about heterogeneous data sources. Does it support only sparql endpoints or it can query on different sources, like hdfs/parquet or some relational db?

Best regards,
