Atomic test and set row operations make this possible. [ACCUMULO-1000][ACCUMULO-1000] added conditional mutations and a conditional writer. A conditional mutation has tests on columns that must pass before any changes are made. These test are executed in server processes while a row lock is held. Below is a simple example of making atomic row changes using conditional mutations. 1. Read columns X,Y,SEQ into a,b,s from row R1 using an isolated scanner. 2. For row R1 write conditional mutation X=f(a),Y=g(b),SEQ=s+1 if SEQ==s.
