Atlan currently only supports native integration with Matillion.
If Talend uses the ELT (Extract, Load, Transform) paradigm, this means that the SQL transformation queries are pushed down into the warehouse. In that case, Atlan will automatically generate the lineage for these transformations by parsing the SQL statements extracted from the query history of the data warehouse. Lineage for the extract and load steps is not automated for Talend but is supported for Fivetran.
However, if the transformation is taking place outside the warehouse, Atlan will need access to the transformation queries to generate the lineage. This access can either be gained via a Git repository if utilized or by sharing the queries or stored procedures in a shared location, such as an S3 bucket.
