+        Where column values to be compared in a query were of the
+        <literal>VARCHAR</literal> or
<literal>VARBINARY</literal>
+        types, <literal>NDBCLUSTER</literal> passed a value padded to
+        the full size of the column, which caused unnecessary data to be
+        sent to the data nodes. This also had the effect of wasting CPU
+        and network bandwidth, and causing condition pushdown to be
+        disabled where it could (and should) otherwise have been
+        applied.
