Connector-side Data Sampling
Datazoom now offers more capabilities to control data flow to Connector destinations. With Connector-side Sampling, customers can set a percentage of data that should be sent to a specific Connector destination. This is useful for managing costs or data caps within specific analytic tools while still allowing full data sets to be collected and sent to Data Warehouses or other Connectors without service level caps or cost concerns.
Connector Sampling is done based on the User Session. Customers will receive all events from a user whose session is deemed to be "in the sample". This ensures completeness of data set for a user. Each Connector configuration features a Sampling Rate slider that will determine the percentage of user sessions included in the sample. The default value is 100%.
Please note, if a sampling rate is changed on an active Connector config, this may result in some partial data from active sessions that are added or dropped from the session. Also, the Sampling Rate as configured in the UI is a target percentage, the actual amount of data and sessions included in the sample may differ depending on a variety of factors. Higher rates of usage will improve accuracy of sampling, reducing deviations, bringing the actual sampling rate closer to the target rate.
