parse explain SELECT DISTINCT c FROM sbtest1 WHERE id BETWEEN 5017 AND 5116 ORDER BY c; err=unknown operator type ExchangeSender_31
=====================================================================
SQL:
explain SELECT c FROM sbtest1 WHERE id BETWEEN 5026 AND 5125;

Plan1:
Projection_4              |  100.00  |  root          |               test1.sbtest1.c
└─TableReader_8       |  100.00  |  root          |               data:TableRangeScan_7
  └─TableRangeScan_7  |  100.00  |  cop[tiflash]  |  table:sbtest1range:[5026,5125], keep order:false

Plan2:
Projection_4              |  100.00  |  root       |               test1.sbtest1.c
└─TableReader_6       |  100.00  |  root       |               data:TableRangeScan_5
  └─TableRangeScan_5  |  100.00  |  cop[tikv]  |  table:sbtest1range:[5026,5125], keep order:false

Reason:  different operators TableRangeScan_7 and TableRangeScan_5
