读热点为什么在一个tikv节点上，没有均摊到其他tikv节点上去

SELECT b.DB_NAME,b.TABLE_NAME,b.INDEX_NAME,c.STORE_ID,a.ADDRESS,COUNT(b.REGION_ID) FROM INFORMATION_SCHEMA.TIKV_STORE_STATUS a ,INFORMATION_SCHEMA.TIKV_REGION_STATUS b,INFORMATION_SCHEMA.TIKV_REGION_PEERS c
WHERE a.STORE_ID=c.STORE_ID
AND b.REGION_ID=c.REGION_ID
AND c.IS_LEADER=‘1’
AND b.DB_NAME=‘sbtest’
AND b.TABLE_NAME=‘sbtest2’
GROUP BY b.DB_NAME,b.TABLE_NAME,b.INDEX_NAME,c.STORE_ID,a.ADDRESS
ORDER BY 1,2,3,4;
用这个sql查一下也行。
