Subject Re: avoiding hot spot for timestamp prefix key
Date Fri, 22 May 2015 05:18:10 GMT
Does guid change with every key ?

bq. use second part of key

I don't think so. Suppose first row in the parent region is
'1432104178817#321'. After split, the first row in first daughter region
would still be '1432104178817#321'. Right ?
