Subscribe data to MongoDB

Write tables out to MongoDB

One entry in collections per input table, in order. if_collection_exists decides whether an existing collection is replaced or added to.

warning

There are several ways to pass secrets into Tabsdata. See Secrets Management for more info if you are planning to have an LLM register secrets into Tabsdata's credential store.

Can you write the sales vendors and items tables out to mongodb

That is a subscriber, so it goes in a destination collection rather than a source one. The guide and connection template are loaded. Three values left, then I generate and register. Reply with them one per line, or point me at a file that has them:

  • collection name
  • destination address and credentials
  • target collections
everything you need is in

Credentials found. Reading back what is not secret: uri mongodb://db.internal:27017/warehouse, collection warehouse, target collections vendors and items.

Connection written to , and collection warehouse created from it in group destinations. Connection check passed.

The subscriber, registered in warehouse:

from tabsdatak.api import subscriber, TableFrameSpec
from tabsdatak.conn.mongodb import MongoDBDest


@subscriber(
destination=MongoDBDest(
collections_with_ids=[
("sales_db.vendors", None),
("sales_db.items", "item_id"),
],
if_collection_exists="replace",
update_existing=True,
),
input_tables=["sales/vendors", "sales/items"],
)
def write_sales(
vendors: TableFrameSpec,
items: TableFrameSpec,
) -> tuple[TableFrameSpec, TableFrameSpec]:
return (vendors, items)

Execution committed, 0 failures.

Two collections written in warehouse, one per input table:

┌────────────┬───────────────┬───────────┐
 collection   from table    documents 
├────────────┼───────────────┼───────────┤
 vendors     sales/vendors  312       
├────────────┼───────────────┼───────────┤
 items       sales/items    8,940     
└────────────┴───────────────┴───────────┘

Input tables are written as collection/table, since a subscriber reads from collections other than its own. A subscriber declares no output_tables: it returns one frame per destination slot, and returning None for a slot writes nothing that run.

Without trigger_by, the subscriber runs whenever any of its input tables gets a new commit, so an export stays current without a schedule.
