@mattab 1500 bytes is actually not correct I guess. It's a VARCHAR(1500) so there are 1500 characters allowed. Depending on the collation one character can have up to 3 or 4 bytes. Might be better to write characters instead maybe
@sgiehl sounds good! updated to this:
@mattab as mentioned in slack by default the referrer page url is also limited to 1024 characters but can be increased to 1500 through the same setting.
