morningman opened a new pull request #1457: Validate the UTF-8 encode of loading data URL: https://github.com/apache/incubator-doris/pull/1457 Currently, Doris only support UTF-8 encoded data. All data will be shown to user in UTF-8 format. So if data loaded in Doris does not UTF-8 encoded, user will see garbled data when querying. I introduce a fast UTF-8 validator from https://github.com/lemire/fastvalidate-utf-8 This validator is highly optimized that it only takes 0.7 CPU cycles to validata a 64k string. And by testing 1GB data load to Doris, the validator has no impact on performance.
