Hello, A new question has been asked in "MariaDB Community" by shortwave. Please answer it at http://mariadb.com/kb/en/determining-size-of-a-row-in-bytes/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I have a small but essential requirement that is making me seriously consider a shift away from MySQL and I am wondering if MariaDB is a viable alternative. I need to measure the size of a row in bytes (easily). Specifically, a table consists of rows belonging to several users. I need to know how much disk space is consumed by each of those users. The only solution I can find in MySQL documentation/forums are inefficient and inaccurate approximations. Does MariaDB provide some way of doing this easily? I have to do it on multiple tables which will probably change, so I don't want to build maintenance overheads in. Also obviously I don't want too much of a performance hit. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/determining-size-of-a-row-in-bytes/
