JDBC Driver for Tableau CRM

Build 21.0.7930


The maximum number of rows to scan to look for the columns available in a table.

Data Type


Default Value



Since Tableau CRM is schemaless, the columns in a table must be determined by scanning table rows. This value determines the maximum number of documents that will be scanned.

Setting a high value may decrease performance. Setting a low value may prevent the data type from being determined properly, especially when there is null data.
