DB_TUNER(1)

💖 db_tuner — analyze and tune btree database 💖

okay so bestie, welcome to db_tuner from the BerkeleyDB Utilities lineup ✨ she's a little utility and she's here to read your btree database's aura and tell you what page size would probably make it thrive 🌸

✨ SYNOPSIS ✨

db_tuner [-c cachesize] -d file [-h home] [-s database] [-v]

🦋 DESCRIPTION 🦋

The db_tuner utility analyzes the data in a btree database, and then suggests a page size that is likely to deliver optimal operation 👑 like… she looks at your data, thinks about it, and goes "girl, try this page size" 💅

🎀 OPTIONS 🎀

• -c cachesize — Specify a value of the cachesize, otherwise, the default value will be set. so like, hand her a number if you have opinions, or just let the default do its thing 🙈
• -d file — Display database statistics for the specified file. ⚠️ here's the tea: if the database contains multiple databases and the -s flag is not specified, the statistics are for the internal database that describes the other databases the file contains — not for the file as a whole. so don't come for her when the numbers look weird, she warned you 😭
• -h home — Specify a home directory for the database environment. 🏠
• -s database — Display page size recommendation for the specified database contained in the file specified with the -d flag. the file's whole thing but you only want the scoop on one database? this is her 🔥
• -v — Display verbose information. she'll yap (affectionately) 🗣️💖

💀 NOTES 💀

okay this part matters, no cap 👑

The db_tuner utility assumes that databases are compacted when analysing the data. The analysis is based on a static view of the data and the data access and update patterns are not take into account. so she's not reading your mind about how you use it, she's reading the data as it sits. just so you know bestie 🫶
