We get here for conditions in form "t.key NOT IN (c1, c2, ...)"
(where c{i} are constants).
Our goal is to produce a SEL_ARG graph that represents intervals:
($MIN<t.key<c1) OR (c1<t.key<c2) OR (c2<t.key<c3) OR ... (*)
where $MIN is either "-inf" or NULL.
The most straightforward way to handle NOT IN would be to convert
it to "(t.key != c1) AND (t.key != c2) AND ..." and let the range
optimizer to build SEL_ARG graph from that. However that will cause
the range optimizer to use O(N^2) memory (it's a bug, not filed),
and people do use big NOT IN lists (see BUG#15872). Also, for big
NOT IN lists constructing/using graph (*) does not make the query
faster.
So, we will handle NOT IN manually in the following way:
* if the number of entries in the NOT IN list is less then
NOT_IN_IGNORE_THRESHOLD, we will construct SEL_ARG graph (*)
manually.
* Otherwise, we will construct a smaller graph: for
"t.key NOT IN (c1,...cN)" we construct a graph representing
($MIN < t.key) OR (cN < t.key) // here sequence of c_i is
// ordered.
A note about partially-covering indexes: for those (e.g. for
"a CHAR(10), KEY(a(5))") the handling is correct (albeit not very
efficient):
Instead of "t.key < c1" we get "t.key <= prefix-val(c1)".
Combining the intervals in (*) together, we get:
(-inf<=t.key<=c1) OR (c1<=t.key<=c2) OR (c2<=t.key<=c3) OR ...
i.e. actually we get intervals combined into one interval:
(-inf<=t.key<=+inf). This doesn't make much sense but it doesn't
cause any problems.
