#2317 feat(extractors): add tap-diffgen (plinxore variant) Pull request opened by plinxore Summary Adds

tap-diffgen

(plinxore variant) to the extractors index.

tap-diffgen

is a generic Singer tap for the "diffgen" pattern: an application-level audit-log table that journals every `INSERT`/`UPDATE`/`DELETE` made to other tables in the same database (columns:

id

,

tablename

,

table_id

,

op

,

ts_created

). Instead of reading a target table directly, the tap replays that log since the last bookmark and, per event: • `i`/`u` (insert/update): repulls the affected row fresh from the target table and emits it with

is_deleted: false

. •

d

(delete): emits a tombstone -- just the primary key,

is_deleted: true

, every other business column

null

. This is what a plain timestamp-filtered incremental extraction can never represent on its own: a deleted row doesn't show up in a

WHERE updated_at > ...

query, so deletes silently vanish downstream. Supports PostgreSQL and MySQL. Each configured table also has a

tombstones_only

mode, for a table that already has a separate, conventional incremental tap and just needs the DELETE gap filled. Repo: https://github.com/plinxore/tap-diffgen PyPI: https://pypi.org/project/plinxore-tap-diffgen/ Test plan • Settings scraped from the real, published
