The Airbyte Cumul.io destination connector allows you to stream data into Cumul.io from any Airbyte Source.

Cumul.io is an Embedded analytics SaaS solution that enables other SaaS companies to grow with an engaging customer analytics experience, seamlessly embedded in their product. Cumul.io's intuitive, low-code interface empowers business users with insight-driven actions in record time without straining engineering resources from the core product.

In order to use the Cumul.io destination, you'll first need to create a Cumul.io account (if you don’t already have one). After logging in to Cumul.io, you can generate an API key and token in your Profile -> API Tokens. To set up the destination connector in Airbyte, you'll need to provide the following Cumul.io properties:

  • "Cumul.io API Host URL": the API host URL for the Cumul.io environment where your Cumul.io account resides (i.e. https://api.cumul.io for EU multi-tenant users, https://api.us.cumul.io/ for US multi-tenant users, or a VPC-specific address). This property depends on the environment in which your Cumul.io account was created (e.g. if you have signed up via https://app.us.cumul.io/signup, the API host URL would be https://api.us.cumul.io/).
  • "Cumul.io API key": a Cumul.io API key (see above how to generate an API key-token pair)
  • "Cumul.io API token": the corresponding Cumul.io API token (see above how to generate an API key-token pair)

As soon as you've connected a source and the first stream synchronization has succeeded, the desired Dataset(s) will be available in Cumul.io to build dashboards on (Cumul.io's "Getting started" Academy course might be interesting to get familiar with its platform). Depending on the synchronization mode set up, the next synchronizations will either replace/append data in/to these datasets!

If you have any questions or want to get started with Cumul.io, don't hesitate to reach out via our contact page.

Sync modesSupported?(Yes/No)Notes
Full Refresh - AppendYes/
Full Refresh - ReplaceYes/
Incremental Sync - AppendYes/
Incremental - Append + Deduped NoCumul.io's data warehouse does not support dbt (yet).
FeatureSupported?(Yes/No)Notes
NamespacesYes(Highly recommended) A concatenation of the namespace and stream name will be used as a unique identifier for the related Cumul.io dataset (using Tags) and ensures next synchronizations can target the same dataset. Use this property to ensure identically named destination streams from different connections do not coincide!
Clear dataYesExisting data in a dataset is not deleted upon resetting a stream in Airbyte, however the next synchronization batch will replace all existing data. This ensures that the dataset is never empty (e.g. upon disabling the synchronization), which would otherwise result in "No data" upon querying it.
Airbyte data typesRemarks
Array & ObjectTo support a limited amount of insights, this connector will stringify data values with type Array or Object (recommended by Airbyte) as Cumul.io does not support storing nor querying such data types. For analytical purposes, it's always recommended to unpack these values in different rows or columns (depending on the use-case) before pushing the data to Cumul.io!
Time with(out) timezoneWhile these values will be stored as-is in Cumul.io, they should be interpreted as hierarchy* (i.e. text/string, see Cumul.io's data types Academy article). Alternatively, you could either provide a (default) date and timezone for these values, or unpack them in different columns (e.g. hour, minute, second columns), before pushing the data to Cumul.io.
Timestamp without timezoneCumul.io does not support storing dates without timestamps, these timestamps will be interpreted as UTC date values.
Number & Integer data types with NaN, Infinity, -Infinity valuesWhile these values will be stored as-is in Cumul.io, they will not support numeric aggregations such as sum, avg, etc. (using such aggregations on these values likely causes unexpected behavior). Ideally, such values are converted into meaningful values (e.g. no value, 0, a specific value, etc.) before pushing the data to Cumul.io.
BooleanBoolean values will be stringified (recommended by Airbyte) and result in a hierarchy column type (i.e. text/string, see Cumul.io's data types Academy article). You could use Cumul.io's hierarchy translation (see this Academy article) to assign translations to true and false that are meaningful to the business user in the column's context.
All other data typesShould be supported and correctly interpreted by Cumul.io's Data API service*.

*Note: It might be that Cumul.io's automatic typing could initially interpret this type of data wrongly due to its format (see Possible future improvements below), you could then alter the column type in the Cumul.io UI to try changing it manually.

Each replicated stream from Airbyte will output data into a corresponding dataset in Cumul.io. Each dataset will initially have an Airbyte - <namespace><stream_name> English name which can be further adapted in Cumul.io's UI, or even via API. If the request of pushing a batch of data fails, the connector will gracefully retry pushing the batch up to three times, with a backoff interval of 5 minutes, 10 minutes, and 20 minutes, respectively.

The connector will associate one or more of the following tags to each dataset:

  • [AIRBYTE - DO NOT DELETE] - <namespace><stream_name>: this tag will be used to retrieve the dataset ID and its current columns from Cumul.io, and will be associated with the dataset after the first batch of data is written to a new dataset.
  • [AIRBYTE - DO NOT DELETE] - REPLACE DATA: this tag will be associated to a dataset when it should be "resetted" (i.e. the existing data should be replaced, see Feature -> Reset data above). The first batch of data of the next synchronization will replace all existing data if this tag is present on a dataset.

As noted in the tag name, it is important to never remove such tags from the dataset(s) nor manually set them on other datasets. Doing so might break existing or new synchronizations!

To ensure the most performant queries, we recommend to denormalize your data as much as possible beforehand (this ensures that the least amount of joins are required to achieve your desired insights). Denormalized datasets also ensure that they can be easily consumed by less technical users, who often do not understand relations between tables! Instead of denormalizing your datasets to specific insights, it is recommended to set up one or more dimensional data models that support all kinds of slicing and dicing within a dashboard: this ensures a flexible & scalable setup which is easy-to-understand and performant-to-query!

This Cumul.io blog post goes into more detail on why customer-facing analytics requires a simple data model: https://blog.cumul.io/2022/12/07/why-a-dimensional-data-model-for-embedded-analytics/.

Cumul.io uses an OLAP database to ensure the most performant concurrent "Read" queries on large amounts of data. OLAP databases, such as Cumul.io's database, are however often less suitable for a lot of "Write" queries with small amounts of data.

To ensure the best performance when writing data, we recommend synchronizing larger amounts of data less frequently rather than smaller amounts of data more frequently!

  • In case of many concurrent synchronizations, the following issues might arise at one point (not evaluated yet):
    • The combination of all write buffers' data could cause memory overload, in that case it might be interesting to alter the flush rate by changing the flush_interval variable in destination_cumulio/writer.py (currently set to 10 000, which is the maximum amount of data points that can be sent via Cumul.io's Data API service in a single request, see note here). We do recommend keeping the flush_interval value as high as possible to ensure the least amount of total overhead on all batches pushed!
    • Having more than 200 concurrent Airbyte connections flushing the data simultaneously, and using the same Cumul.io API key and token for each connection, might run into Cumul.io's API Rate limit. As this will rarely occur due to Cumul.io's burstable rate limit, we recommend using separate API key and tokens for identical destination connectors in case you would expect such concurrency. Note that synchronizing multiple streams in a single connection will happen sequentially and thus not run into the rate limit.
  • The current connector will not take into account the Airbyte source data types, instead Cumul.io's API will automatically detect column types based on a random data sample. If Cumul.io's detected data type is not as desired, it's possible to alter the column's type via Cumul.io's UI to manually change the column type (e.g. if a VARCHAR column would only contain numeric values, it could initially be interpreted as a numeric column in Cumul.io but can at any point be changed to hierarchy if more appropriate).
    • As a future improvement, it is possible to:
      1. Create a new dataset - Create Dataset API Documentation
      2. Create the appropriate tag ([AIRBYTE - DO NOT DELETE] - <stream_name>) and associate it with the newly created dataset (in destination_cumulio/client.py, a method _validate_tag_dataset_id_association(stream_name, dataset_id) is defined which could be used for this step)
      3. Create each column with the correct Cumul.io type - Create Column API Documentation
      4. Associate each column with the dataset - Associate Dataset Column API Documentation
      5. From there on out, you can replace/append data for this dataset based on the tag (already implemented).
