A very useful and handy implementation of Load step from ELT acronym.

Use this example to build your own Extract - Load solution and take into account all the possible outcomes and issues you may face in advance:

– Handling duplicate rows (even when uniqueness constraint is not enforced)
– Coping with DELETEs on source side (hard deletes)
– Allowing data inspection and time travel with metadata attributes
– Examples for Amazon Redshift, Google BigQuery, Snowflake
