Meltano: ELT for DataOps with Douwe Maan - Software Engineering Daily
"ELT is a process for copying data from a source system into a target system. It stands for “Extract, Load, Transform” and starts with extracting a copy of data from the source location. It’s loaded into the target system like a data warehouse, and then it’s ready to be transformed into a usable format for things like modern cloud applications.
The company Meltano provides code that manages ELT pipelines through an open-source, self-hosted, CLI-first, debuggable, and extensible process. Meltano projects manage your Singer tap and target configurations to easily select which entities and attributes to extract. These pipelines track their own incremental replication state so they can pick up where the previous run left off. Once your raw data is in its target source, Meltano helps you transform it into a usable format. These pipelines can run on a schedule and be fed to supported orchestrators like Apache Airflow."
