Data types
The following table shows the default mapping from Qlik Replicate data types to Google Cloud Storage target data types. Note that the data type mapping is only relevant if the Create metadata files in the target folder option is enabled.
For information on source data type mappings, see the section for the source endpoint you are using.
For additional information about Qlik Replicate data types, see Replicate data types.
