static final String GROUP_BY_STATE
IGroupByStatefor the aggregation operator, including the SELECT value expressions to be projected, the optional GROUP BY value expressions, and the optional HAVING value expressions.
static final String GROUP_BY_REWRITE
IGroupByRewriteState, which is a rewrite of the
GroupByStatethat allows for certain optimizations. This data is a required annotation because the rewrite includes anonymous variables and the identity of those anonymous variables MUST be stable across each invocation of the operator. This requirement exists both for pipelined aggregation operators running on a single node and for distributed aggregation operators running on a cluster.
