Hi all,

We are detecting a performance problem in our mysql cluster.
Executing the following query: "select operation_type, count (operation_type) from ndbinfo.cluster_operations group by operation_type" , we have notice a high number of operation type "READ-SH" in conjunction with a drastic performance drop.
Looking in the documentation we did not find information on the meaning of that kind of operation,do you know what it means?

Thanks in advance

Giuseppe
