PostgreSQL is a powerful open-source object-relational database system that extends the SQL language with advanced features. It’s known for its reliability, data integrity, and support for complex queries, making it ideal for enterprise applications, data warehousing, and web services.

0. Required pre work

In order to connect Nekt to a database, you have to do some pre work to ensure access is granted in a secure way. So, make sure to check this guide before proceeding.

​
1. Add your PostgreSQL access

  1. Once you have done the pre work defined in section 0, you can inform your database accesses. In the Sources tab, click on the “Add source” button located on the top right of your screen. Then, select the Postgres option from the list of connectors.
  2. Click Next and you’ll be prompted to add your database access.
  3. Click Next.

​
2. Select your Postgres streams

  1. The next step is letting us know which streams you want to bring. You can select entire groups of streams or only a subset of them.
    Tip: The stream can be found more easily by typing its name.
  2. Click Next.

​
3. Configure your Postgres data streams

  1. Customize how you want your data to appear in your catalog. Select a name for each table (which will contain the fetched data) and the type of sync.
  • Table name: we suggest a name, but feel free to customize it. You have the option to add a prefix and make this process faster!
  • Sync Type: you can choose between INCREMENTAL, FULL TABLE and LOG BASED.
    • Incremental: every time the extraction happens, we’ll get only the new data - which is good if, for example, you want to keep every record ever fetched and save some extraction time.
    • Full table: every time the extraction happens, we’ll get the current state of the data - which is good if, for example, you don’t want to have deleted data in your catalog.
    • Log based: to support log based syncs, you have to do a little pre work on your database. Check the procedure here.
  1. Click Next.

​
4. Configure your Postgres data source

  1. Describe your data source for easy identification within your organization. You can inform things like what data it brings, to which team it belongs, etc.
  2. To define your Trigger, consider how often you want data to be extracted from this source. This decision usually depends on how frequently you need the new table data updated (every day, once a week, or only at specific times).

​
Check your new source!

  1. Click Done to finalize the setup. Once completed, you’ll receive confirmation that your new source is set up!
  2. You can view your new source on the Sources page. Now, for you to be able to see it on your Catalog, you have to wait for the pipeline to run. You can now monitor it on the Sources page to see its execution and completion. If needed, manually trigger the pipeline by clicking on the refresh icon. Once executed, your new table will appear in the Catalog section.
