The token function is apparently converting > integers to strings leading to seemingly unpredictable results. > However I find this syntax odd, I feel like I should be able to say > 'token(username) > 0 and token(username) < 10' because from a thrift side I > can page tokens or I can page keys. In this case, I guess, I am only able to > page keys because the token is not returned to the user. > Is token 0 = ''? How do I arrive at the minimal token for and int column. > Should the token() function at least be smart enough to reject integers for > string columns? -- This message is automatically generated by JIRA.
