Hey @terence1988 , I'd change the text to the following (as discussed on Jira):

"Yes. Data types are set up in your warehouse based on the first value that comes in from a source, but you can request data type changes by reaching out to Segment Support. Keep in mind that Segment uses general data types when loading data in your warehouse, for example:

• Changing data type from timestamp to varchar

• Changing data type from integer to float

• Changing data type from boolean to varchar

More granular changes (such as the examples mentioned below) wouldn’t normally be handled by our Support team. These should be made within the warehouse itself:

• Expanding varchar(256) to varchar(2048)

• Updating integer to bigint

• Updating float to float8 "

Thanks!

Thank you for your contribution! Your pull request is merged, but may take a day or two to appear on the site.
