We have added the multi value index, and it should add a new field (
array) to theFieldTypeandColumnInfo. Thearraymarks whether it's an element of the json value.It will affect the behavior of
NeedRestoreData, because when it's anarray, thetpwill returnjson. See https://github.com/pingcap/tidb/pull/39992/files#diff-7f1116d41040b590372f81a91d25057b8ef7f6bdf503f6c2b27af3f35294cda1R93-R95, and it doesn't needRestoreData.See pingcap/tidb#46718 and tikv/tikv#15537
