https://dev.mysql.com/doc/refman/8.0/en/creating-rsa-files-using-openssl.html
This section describes how to use the openssl command to set up the RSA key files that enable MySQL to support secure password exchange over unencrypted connections for accounts authenticated by the sha256_password and caching_sha2_password plugins. Note There are easier alternatives to generating the files required for RSA than the procedure described here: Let the server autogenerate them or use the mysql_ssl_rsa_setup program (deprecated as of MySQL ...
https://dev.mysql.com/doc/refman/8.0/en/creating-ssl-rsa-files-using-mysql.html
MySQL provides these ways to create the SSL certificate and key files and RSA key-pair files required to support encrypted connections using SSL and secure password exchange using RSA over unencrypted connections, if those files are missing: The ...
https://dev.mysql.com/doc/refman/8.0/en/data-size.html
Design your tables to minimize their space on the disk. This can result in huge improvements by reducing the amount of data written to and read from disk. Smaller tables normally require less main memory while their contents are being actively ...
https://dev.mysql.com/doc/refman/8.0/en/dynamic-format.html
Dynamic storage format is used if a MyISAM table contains any variable-length columns (VARCHAR, VARBINARY, BLOB, or TEXT), or if the table was created with the ROW_FORMAT=DYNAMIC table option. Dynamic format is a little more complex than static ...
https://dev.mysql.com/doc/refman/8.0/en/engine-condition-pushdown-optimization.html
This optimization improves the efficiency of direct comparisons between a nonindexed column and a constant. In such cases, the condition is “pushed down” to the storage engine for evaluation. This optimization can be used only by the NDB ...

To use MySQL Enterprise Encryption in applications, invoke the functions that are appropriate for the operations you wish to perform. In releases before MySQL 8.0.30, MySQL Enterprise Encryption's functions are based on the openssl_udf shared ...
https://dev.mysql.com/doc/refman/8.0/en/floating-point-types.html
The FLOAT and DOUBLE types represent approximate numeric data values. MySQL uses four bytes for single-precision values and eight bytes for double-precision values. For FLOAT, the SQL standard permits an optional specification of the precision (but ...
https://dev.mysql.com/doc/refman/8.0/en/general-tablespaces.html
A general tablespace is a shared InnoDB tablespace that is created using CREATE TABLESPACE syntax. The server keeps tablespace metadata in memory for the lifetime of a tablespace. Multiple tables in fewer general tablespaces consume less memory for ...
