You may find significant relief with these suggestions for your my.cnf [mysqld] section
innodb_buffer_pool_size=32G # from 104G because you have 16.8G of data
innodb_buffer_pool_instances=16 # from 64 should be adequate
innodb_lru_scan_depth=100 # from 1024 to conserve 90% CPU cycles used for function.

You will never be allowed to alter any tables used by RDS Services. They are managed by Amazon.
I see you logged in as admin@'%' but Amazon has shielded their source-compiled version of mysqld from allowing anyone to change their managed tables.
Even if SHOW GRANTS; says you have all privileges, you really don't. I have mentioned this years ago (See ...
innodb_buffer_pool_load_at_startup = ON
Tells the server to reload the buffer_pool at startup. This causes a lot of I/O in a short period of time.
Its goal is to make the subsequent queries a little faster, but that may or may not be worth it.
If this is a cloud service, they probably do some regular maintenance, perhaps a backup, at the about the same ...
What you dump using mysqlbinlog --verbose MyPc-bin.000003 --database StackOverflow > C:\test\binlog.txt, that is, the file C:\test\binlog.txt, is not a binary log, so you cannot use it as the source for the binlog command.
What you should do is this:
mysqlbinlog MyPc-bin.000003 --start-position=89925 --stop-position=90568 | mysql -uroot
That is, you need ...
One way to fix the warning is to make sure there are no indexes on columns that may be longer than 767 bytes.
For example: VARCHAR(255) is a common choice for a string column, but if you use the utf8mb4 character set, this can be up to 255 * 4 or 1020 bytes. You would need to shorten this column to VARCHAR(191) so the max length of the string is 191 * 4 or ...
I have found out the problem.
When MySQL 8.0 inverted latitude and longitude, it didn't invert the structure of the geometry itself, but only the representation in spatial functions.
I suppose this information is available somewhere in the documentation, but I personally wasn't able to find anything that clearly states that the change from 5.7 to 8.0 only ...
An alternative method to that suggested above would be to do the following (fiddle here):
CREATE TABLE user
id INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY,
email VARCHAR (256) NOT NULL
The number of fields is irrelevant, since you won't be grouping by them. This is just a sample for demonstration purposes.
CREATE TABLE login_history
Rate Per Second = RPS
Suggestions to consider in your my.cnf [mysqld] section, to help avoid OOM Killer.
innodb_parallel_read_threads=0 # from 4 because you only have 2 CPU's today
open_files_limit=35000 # from 40000 to allow OS to use other 5,000 reported by ulimit -a
temptable_max_mmap=32M # from 1G since you only have 4G total
temptable_max_ram=32M # ...
It's not possible to make a Percona MySQL server 8.0 join a Percona XtraDB Cluster, regardless of version. The 8.0 server has to be Percona XtraDB, otherwise it won't have the necessary Galera libraries and bindings.
change settings in my.ini or mysql.ini
also there is a CPU command in kernel or core of server that lets you allocate CPU resource in the amount of percentage you want.
UTF8 is a variable length encoding.
If 4 bit per character isn't issue in terms of storagewise, you may consider;
UTF8 to UTF8MB4 (supports emoji and more characters)
Also Please move from ...
