Cassandra vs OS x

Jean Tremblay
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? What is your experience with this?

Thanks

Jean

Cost may be a factor? OS X servers would cost a lot more than Linux servers.

Out of curiosity - could you elaborate on that or drop a link? 

Kind regards,

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, 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]

HFS+
The HFS Plus Catalog File is very similar to the HFS Catalog File, 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.

That is the reason for trying to work with ZFS. Unfortunately, it was dropped.
 And that is the reason pcie interface for SSD in my MacBook pro.

The PHP driver from Datastax was released last week.
