Getting started

See Quickstart guide to get started.

Examples

There are several examples available under /examples:

Quickstart examples

hello

Simplest example, append-only

local

Emulated source, without any calls out to the internet

configuration

Shows how to use secrets

hashes

Shows how to calculate hash of fields and use it as primary key. Useful in scenarios where the incoming rows do not have any field suitable to be used as a Primary Key.

user_profiles

Shows the use of Pandas DataFrames to manipulate data prior to sending to Fivetran.

weather

A realistic example, using a public API, fetching data from NOAA

Common patterns for connectors

cursors

multiple_tables_with_cursors

The parent-child relationship between tables from incremental API endpoints, with the complex cursor.

marketstack

This code retrieves different stock tickers and the daily price for those tickers using marketstack API. Refer its Docs

pagination

Simple pagination example templates for the following types of paginations:

• keyset
• next_page_url
• offset_based
• page_number

specified_types

Declares a schema and upserts all data types

unspecified_types

Upserts all data types without specifying a schema

three_operations

Shows how to use upsert, update and delete operations

priority_first_sync_for_high_volume_initial_syncs

Priority-first sync, pfs for short, is very helpful for high volume historical syncs. It is a sync strategy which prioritises fetching the most recent data first so that fresh data is ready for you to use more quickly. This is a simple example of how you could implement the Priority-first sync strategy in a connector.py file for your connection.

Source examples

records with no created_at

Shows how to work with records where the source does not provide a created_at(or equivalent) field. Useful when its desired to keep track of when the record was first observed.

multiple code files

Shows how you can write a complex connector comprising multiple .py files.

aws dynamo db authentication

Shows how to authenticate to aws using IAM role credentials and use it to sync records from dynamodb boto3 package is used to create aws client. Refer its Docs

redshift

This is an example to show how we can sync records from redshift DB via Connector SDK. You would need to provide your redshift credentials for this example to work.

key based replication

This shows key based replication from DB sources. Replication keys are columns that are used to identify new and updated data for replication. When you set a table to use Incremental Replication, you’ll also need to define a replication key for that table.

accelo api connector multithreading enabled

This module implements a connector for syncing data from the Accelo API. It handles OAuth2 authentication, rate limiting, and data synchronization for companies, invoices, payments, prospects, jobs, and staff. It is an example of multithreading the extraction of data from the source to improve connector performance. Multithreading helps to make api calls in parallel to pull data faster. It is also an example of using OAuth 2.0 client credentials flow. Requires Accelo OAuth credentials to be passed in to work.

Additional considerations

We provide examples to help you effectively use Fivetran's Connector SDK. While we've tested the code provided in these examples, Fivetran cannot be held responsible for any unexpected or negative consequences that may arise from using these examples.

Note that API calls made by your SDK connector may count against your service’s API call allocation. Exceeding this limit could trigger rate limits, potentially affecting other uses of the source API.

It's important to choose the right design pattern for your target API. Using an inappropriate pattern may lead to data integrity issues. Review all our examples carefully to select the one that best suits your target API. Keep in mind that some APIs may not support patterns for which we currently have examples.

As with other new connectors, SDK connectors have a 14-day trial period during which your usage counts towards free MAR. After the 14-day trial period, your usage counts towards paid MAR. To avoid incurring charges, pause or delete any connectors you created to run these examples before the trial ends.
