Max Versions

Last Updated: May 25, 2017

Max Versions is a data table attribute used to indicate the maximum number of data versions in each Attribute column of a data table. When the number of the data versions in an Attribute column exceeds the value of Max Versions, the earliest versions will be deleted asynchronously.

After creating a data table, you can use the UpdateTable interface to dynamically change the value of Max Versions.

Because the data exceeding the value of Max Versions will be cleared asynchronously, pay attention to the following information when you dynamically modify the value of Max Versions:

  • The data that exceeds the value of Max Versions is invalid and cannot be viewed or accessed, even though it is not deleted.

  • If you reduce the value of Max Versions, the data that exceeds the new value will be deleted asynchronously.

  • If you increase the value of Max Versions, the data that exceeds the old value but is not deleted yet can be accessed again.
