HFS: The Catalog File, which stores all the file and directory records in a single data structure, results in performance problems when the system allows multitasking <http://en.wikipedia.org/wiki/Computer_multitasking>, as only one program can write to this structure at a time, meaning that many programs may be waiting in queue due to one program "hogging" the system.[2] <http://en.wikipedia.org/wiki/Hierarchical_File_System#cite_note-2>
HFS+ The HFS Plus Catalog File is very similar to the HFS Catalog File <http://en.wikipedia.org/wiki/Hierarchical_File_System#Design>, the main differences being records are larger to allow more fields and to allow for those fields to be larger (for example to allow the longer 255-character unicode file names in HFS Plus). A record in the HFS Catalog File is 512 bytes in size, a record in the HFS Plus Catalog File is 4 KB in Mac OS and 8 KB in OS X. Fields in HFS are of fixed size, in HFS Plus the size can vary depending on the actual size of the data they store. 2015-04-07 13:41 GMT+02:00 Serega Sheypak <serega.shey...@gmail.com>: > It's single-threaded for writing :) > > 2015-04-07 13:13 GMT+02:00 Jean Tremblay < > jean.tremb...@zen-innovations.com>: > >> Hi, >> >> Why do everyone say that Cassandra should not be used in production on an >> Mac OS x? >> Why would this not work? >> Are there anyone out there using OS x in production?
