Description:
The sdi file losts after executing `alter database`
How to repeat:
mysql> create database db1;
Query OK, 1 row affected (8.09 sec)
$ls -lh db1*
-rw-r----- 1 yinfeng.zwx users 210 Oct 6 17:04 db1_22.SDI
mysql> alter database db1 default charset gbk;
the serial number of new sdi file is not increased according to gdb:
Breakpoint 3, (anonymous namespace)::write_sdi_file (fname=".//db1_22.SDI", sdi=
"{\n \"sdi_version\": 1,\n \"dd_version\": 1,\n \"dd_object_type\": \"Schema\",\n \"dd_object\": {\n \"name\": \"db1\",\n \"default_collation_id\": 28,\n \"created\": 0,\n \"last_altered\":"...)
at /u01/yf_57/mysql-server/sql/dd/impl/sdi_file.cc:45
45 File sdif= mysql_file_create(key_file_sdi, fname.c_str(), CREATE_MODE,
And then the file is unlinked after being updated.

Check the directory:
$ls -lh db1*
total 0
Suggested fix:
Increase the serial number of sdi file when the database is altered.
