They will never run on a cluster and will never see even dozens of concurrent users, let alone hundreds or thousands. Sometimes simplicity and ease of use is enough of a reason to use a tool. PStore has many drawbacks, but it's sometimes a great tool for the job. There are huge numbers of applications being written for small, targeted audiences.

Apart from the fact that it doesn’t scale to a setup with more than 1 box, it is much slower than using the database for session storage, for example. ou really shouldn’t be using Pstore for Rails.

I am an author of dm-tokyo-cabinet-adapter. I haven't worked on the adapter, and my implementation is quite old (implemented before Table Database API was supported by TC, so most of my code is redundant) and there is a bug which I haven't fixed yet, so go for it. Feel free to ping me if you have any questions on my implementations. Hi,Scott. I am an author of dm-tokyo-cabinet-adapter.

However, PStore can be perfectly appropriate. Not all apps are going to see heavy use. In fact, I'd wager that the majority of apps that actually get built and put into production are apps targeted at small, specific userbases, with no particular performance concerns, and no need to scale beyond a single box. It's all a matter of knowing what you are doing, and selecting the tools to match, and there's no reason at all not to use PStore if it will satisfy the needs of the project. Conversely, if it won't, then there is no reason to use it. It is a tool with some significant limitations, for certain.

Even with marshalling the data like PStore does, gdbm was about 50 times faster. <a href="http:\/\/www.automobileupdates.com" target="_blank">Fiat</a> Regarding performance of PStore: I was using PStore for storage, and then switched to using gdbm instead (because Ruby came with bindings for it.)
