Each Keboola Connection standard project has two kinds of limits:
Business limits are set in your contract and define the business usage of our platform. This can be seen as the size of your project. Exceeding them will earn you a call from us and a possible contract update conversation.
Platform limits represent what our platform is technically capable of. Reaching or exceeding these limits is either technically impossible, or it carries a risk of degraded performance.
Note: These limits apply to standard Keboola Connection projects. The limits for pay-as-you-go projects might differ.
Business limits are set for each project upon entering into the subscription.
All business limits are soft limits. Exceeding them will not cause the project to be restricted. However, if you substantially and constantly exceed the limits, you will be contacted by us with a project upgrade suggestion because you are using more than you have paid for. You can also request an upgrade by clicking the Request Increase button creating a support ticket.
Business limits vary based on your contract (refer to it to see which ones apply in your case):
Project Power Credits is proportional to the sum of the elapsed time of all jobs executed in Keboola Connection. Measured in milliseconds, presented in hours (1 hour = 3,600 seconds). Every job consumes different amount of Project Power Credits, based on
Below you will find an overview of time credits consumed by individual Keboola Connection job types. If you need more information, please contact your CSM.
|Types of jobs in Keboola Connection||Base job||Time credits|
|Extractor job||1 hour||2|
|Writer job||1 GB out||0.2|
|SQL job / Workspace|
|Data Science job / Workspace|
|Deployed & running ML model (BETA)||1 hour||0.1|
|DWH Direct query|

Types of backend sizes used for jobs
|SMALL (SQL)||Snowflake SMALL DWH or equivalent|
|MEDIUM (SQL)||Snowflake MEDIUM DWH|
|LARGE (SQL)||Snowflake LARGE DWH|
|XSMALL (Python,R, Components)||8 GB RAM, 1 CPU cores, 150GB SSD, shared|
|SMALL (Python,R, Components, DataApp)||16 GB RAM, 2 CPU cores, 150GB SSD, shared|
|MEDIUM (Python,R, Components)||32 GB RAM, 4 CPU cores, 150GB SSD, shared|
|LARGE (Python,R, Components)||114 GB RAM, 14 CPU cores, 1TB SSD, dedicated|
|SMALL (dbt)||Snowflake SMALL DWH or equivalent|
|REMOTE (dbt)||Using user’s remote DWH|
The table storage size is measured as it is reported by the underlying backend. This means that the reported size is substantially smaller than the size of imported raw CSV files, thanks to compression used by the database backend. This also means that reported sizes of the same data may differ slightly across projects with different backends (or between buckets in a project with mixed backends).
Apart from the business limits, there are limitations to what the Keboola Connection platform can take. These limits are either defined by the underlying technologies or by what we believe is the correct use of the platform. The technical platform limits are non-negotiable and cannot be upgraded by updating the contract. Nonetheless, we certainly would like to hear if you hit them.
The platform limits may be soft limits or hard limits. They are also likely to change (improve) over time as the development continues and often can be mitigated by a good project design. Contact us for advice if you are concerned about any of them!
For example, the Redshift backend allows the maximum table cell size of 64kB. This is a hard limit and nothing can be done about it as long as Redshift is a hard requirement (the Snowflake backend can take larger cells).
As another example, you should not have more than 200 tables in a single bucket. This is a soft limit related to how we believe the Storage component should be used. Nothing prevents you from exceeding that limit but the component performance may degrade.
The full list of the platform limits is available as a separate document.
