RSS to Databricks: How to Move Your Data

Moving RSS into Databricks makes sense for one reason: you intend to do something with the article text. Feeds are tiny, so this is never a volume decision, and a lakehouse is a heavy platform for a few thousand rows unless language processing is the point.

This guide covers the managed path with Airbyte. Two things shape the build: the RSS specification makes item identifiers optional, so there is no primary key at all, and that turns deduplication into modelling work rather than a pipeline setting.

Rss to Databricks at a glance:

Why move data from Rss to Databricks?

One situation genuinely suits this, and it is worth being clear about the other.

The good case is doing something to the text. Classifying articles by topic, extracting named entities, scoring relevance against a watchlist or embedding items for a retrieval layer are all language processing tasks, and a lakehouse is where that work happens comfortably beside the data rather than in a separate service.

The poor case is storage, because feeds are small and a database would hold them for a fraction of the operational effort. If you simply want a queryable record of what was published, Rss to PostgreSQL does that job with less machinery, and choosing it is not a compromise.

What do you need before you start?

Four things, and the first is a question rather than a credential:

Confirmation that the text is the point. If nobody intends to process the article content, this destination is more platform than the job needs and a database will serve you better at a fraction of the effort.

A feed URL, and one source per feed. That is the entire source configuration, with no credentials since feeds are public. Monitoring twenty publications means twenty sources. The RSS source documentation covers the setup and the fields you receive.

A check that each feed publishes proper dates. Incremental sync uses the published date as its cursor, so a feed that omits or mangles them behaves unpredictably, and plenty of feeds in the wild are careless about this.

Permission to create Volumes in Unity Catalog. Staging goes through Avro files written into a Volume, which is separate from creating tables and worth requesting early.

If your workspace restricts traffic by IP, add the Airbyte Cloud IP addresses to the allow list before you begin.

How do you build an Rss to Databricks pipeline in Airbyte?

Step 1: Check this is a text processing problem

Ask what will be done with the items once they land. Classification, entity extraction, embedding or scoring are all reasons to be here. Counting articles per publication and storing a searchable record are not, and neither justifies the operational weight of a lakehouse for a dataset measured in thousands of rows. One conversation settles it and prevents a correct pipeline nobody needed.

Step 2: Configure the RSS source

Click Sources in the left navigation, then New Source, and select RSS, following adding a source. Supply the feed URL, which is the only required field. One stream of items arrives carrying title, link, description, author and category as strings, with the date converted into a proper UTC datetime.

Step 3: Configure the Databricks destination

Click Destinations, then New Destination, and select Databricks, following adding a destination. Supply the workspace details, warehouse or cluster, catalogue and schema. Where several feeds land in one place, name the tables so the publication is obvious, since a list of feed tables becomes unreadable quickly.

Step 4: Create the connections and be gentle about frequency

Click Connections, then New connection for each feed, selecting the stream and a sync mode. Hourly suits most publications, and anything faster mostly adds load to somebody else's server for very little gain. These are not your machines and nothing obliges them to keep serving you.

Then build the silver layer, because the landing tables contain duplicates by design and nothing upstream can prevent that.

What does a lakehouse give a dataset this small?

Somewhere to run models beside the data, which is the entire argument. A feed of articles is a few thousand rows of text, and the reason to put text in a lakehouse is never storage: it is that classification, entity extraction and embedding are notebook work, and doing them where the data already sits beats shuttling it to another service and back.

That makes the medallion layers unusually clean here. Bronze holds items exactly as the feed produced them, including the duplicates. Silver deduplicates and normalises across publications so a competitor's feed and a regulator's feed share a shape. Gold holds whatever your models produced, which is the layer anybody actually reads.

It also means normalising across feeds is worth doing properly. Different publications populate the optional fields differently, some using categories heavily and others not at all, some putting full article text in the description and others a single line. A silver table that reconciles those differences is what lets a model treat twenty sources as one corpus rather than twenty special cases.

Why does deduplication become your job?

Because the RSS specification does not require an item identifier. An item may carry a guid intended to identify it and it may not, so the connector cannot offer a primary key for feeds in general and works from a cursor on the published date instead. Nothing in the pipeline can recognise an item it has already seen.

Publishers make that visible quickly, since they edit items, republish them and adjust timestamps, and each of those produces another row. For a counting exercise that is an annoyance. For a text processing pipeline it is worse, because embedding or classifying the same article five times wastes compute and skews anything that aggregates over the results.

Deduplicate in silver on the item's link, which is effectively unique in most feeds even where guid is absent, and use the extraction timestamp to decide which version wins rather than the published date, since the first is under your control and the second is under the publisher's. Do that before anything expensive runs, so your models process each article once rather than once per sighting.

Frequently asked questions

Is a lakehouse overkill for RSS?

For storage, yes. It earns its place only when you intend to run language processing over the article text, which is notebook work best done beside the data.

Why does the same article appear more than once?

There is no primary key, because the specification makes item identifiers optional. Deduplicate on the link in a silver table before anything expensive runs.

Can one source cover several feeds?

No, a source takes one feed URL. Each publication needs its own source and connection, which multiplies what you maintain even though each is tiny.

Which timestamp should decide the winning version?

The extraction timestamp, since it is under your control. The published date belongs to the publisher and can be changed retrospectively.

Can I do this without writing code?

The pipelines, yes, and each is a one-field setup. The deduplication and the models are the actual work, and they are the reason to choose this destination.

Get your Rss data into Databricks

Confirm the text is the point before building anything, because feeds are small and a database is the better answer if nobody will process the content. Check each feed publishes proper dates, and expect one source per publication. Then deduplicate on the link in silver using the extraction timestamp, and do it before your models run, since embedding the same article five times is the specific waste this source invites.

Airbyte's connector catalog includes 600+ pre-built connectors, so public publications can feed the models that read them. For the same source onto a message bus, see Rss to Kafka, and for another small operational source into the same destination, n8n to Databricks.
