If you have restricted access in your Amazon S3, you must allow access to it from Treasure Data. The TOKENIZE_JA function can be used to allow access even if your S3 environment is restricted. The static IPs used to allow access must be the same as those used for your Result Workers. If necessary, contact TD Support.
If your Amazon S3 does not restrict access, no configuration using the TOKENIZE_JA function is required.
