> With PHOENIX-2566, there's a subtle change in projected tables in that a column may end
up being not nullable where as before it was nullable when the family name is not null. I've
kept the old behavior with [this|https://git-wip-us.apache.org/repos/asf?p=phoenix.git;a=blobdiff;f=phoenix-core/src/main/java/org/apache/phoenix/compile/TupleProjectionCompiler.java;h=fccded2a896855a2a01d727b992f954a1d3fa8ab;hp=d0b900c1a9c21609b89065307433a0d37b12b72a;hb=82ba1417fdd69a0ac57cbcf2f2327d4aa371bcd9;hpb=e126dd1dda5aa80e8296d3b0c84736b22b658999]
commit, but would you mind confirming what the right thing to do is, [~maryannxue]?
> Without this change, the explain plan changes in SortMergeJoinMoreIT.testBug2894() and
the assert fails. Looks like the compiler ends up changing the row ordering.
