Re: [Maria-discuss] A federation bug was identified.

      Hi, 최혁규,

It might be a bug, but it's impossible to tell for sure with the
information you've provided. Please, report a bug at jira.mariadb.org
and answer questions there as needed.

You can also specify there whether you use Federated or FederatedX,
what is the version of the second server and what is the structure of
the remote table.

Regards,
Sergei

A federation bug was identified.
I have confirmed that the select where query does not work in the multi
index field of some federated tables.
A field in the table is used as a multi index.
My server version : 10.8.2-MariaDB
However, there is no problem with the server used in the previous version.
The previous version is Server version: 10.5.10-MariaDB.
The tested method was compared by creating a federated table on two servers
with different versions.
1. 10.5.10 - MariaDB
  -> All queries are normally searched.
2. 10.8.2 - MariaDB
-> Symptoms were confirmed in some multi index types.
--> The table field datatype is (int, datetime)
This is the table I created and the select query.
