The Lock Monitor is the same as the Standard Monitor except that it includes additional lock information. Enabling either monitor for periodic output turns on the same output stream, but the stream includes extra information if the Lock Monitor is ...

Because the file contents are sent over the connection by the client to the server, using LOCAL is a bit slower than when the server accesses the file directly. BIT values cannot be loaded directly using binary notation (for example, b'011010'). The ...

In this case, the GROUPING() return value represents a bitmask combined from the results for each expression, where the lowest-order bit corresponds to the result for the rightmost expression. The value is a 128-bit number represented as a utf8mb3 ...The function return value and type are the same as the return value and type of its argument, but the function result is not checked for the ONLY_FULL_GROUP_BY SQL ...

Additional storage is required for tables using the NDB$EPOCH() and NDB$EPOCH_TRANS() functions; from 1 to 32 bits extra space per row is required, depending on the value passed to the function. This column should be defined as follows: ...
https://dev.mysql.com/doc/refman/8.0/en/charset-unicode-utf32.html
utf32 uses 32 bits for every character, unlike ucs2 (which uses 16 bits for every character), and unlike utf16 (which uses 16 bits for some characters and 32 bits for others). The utf32 character set is fixed length (like ucs2 and unlike utf16).
https://dev.mysql.com/doc/refman/8.0/en/enterprise-encryption-functions-legacy.html
key_len is the key length in bits for RSA and DSA keys. The minimum allowed key length in bits is 1,024, and the maximum allowed key length is 16,384 for the RSA algorithm or 10,000 for the DSA algorithm. Server administrators can impose additional ... In releases before MySQL 8.0.30, MySQL Enterprise Encryption's functions are based on the openssl_udf shared ...

Does replication work on mixed hardware architectures (for example, the source runs on a 64-bit machine while replicas run on 32-bit machines)? A.14.1. Does replication work on mixed hardware architectures (for example, the source runs on a 64-bit ... In the following section, we provide answers to questions that are most frequently asked about MySQL ...
https://dev.mysql.com/doc/refman/8.0/en/hexadecimal-literals.html
In numeric contexts, MySQL treats a hexadecimal literal like a BIGINT UNSIGNED (64-bit unsigned integer). Hexadecimal literal values are written using X'val' or 0xval notation, where val contains hexadecimal digits (0..9, A..F). Lettercase of the ...
