I want to develop a tap for mssql which includes support for change tracking for incremental replication (not currently supported on any taps). However, I'm hitting a bit of a brick wall for documentation. I downloaded the cookiecutter, read the docs available at https://sdk.meltano.com/, and have reviewed some repos like

tap-postgres

Are there any other resources I should be aware of?

The resources I have run across are the following. This is not an inclusive list just only the links I know of. https://sdk.meltano.com/en/v0.40.0/incremental_replication.html https://docs.meltano.com/guide/integration#setting-metadata https://docs.meltano.com/guide/integration#replication-methods https://docs.meltano.com/guide/integration#incremental-replication-state There are a multiple areas of the SDK that contain code to allow incremental extracts but a good starting point to look at is the

get_records()

method of the

SQLStream

class.

@Conner Panarella , you're certain https://github.com/wintersrd/pipelinewise-tap-mssql/blob/master/tap_mssql/sync_strategies/incremental.py doesn't support incremental?

@visch It does support incremental, but not the change tracking mechanism. It supports CDC, though.

So you mean CDC, not incremental. got it
