Have You Yet Tested What Is The Limit?

Сообщение QuickBird » 01 июн 2019, 22:03

Вы Уже Проверили, Что Такое Предел?


First off I wish to compliment the team of SAS Planeta for creating a very good product, I know it's been a lot of work. Spasiva.

I have found SasPlanet portable, tweakable, low demanding, very handy compared to other GIS, it has only crashed when I forced big downloads, blin it is good.

It needs to be noticed something about the "Use system proxy settings". The Proxy doesn't proxy at all, the app connects fully in the open and clear. This is that your ISP see the server you connect and google, etc they all see your IP.


Now the questions section.


WHAT IS THE LIMIT?


I have an install that went over the 25GB (160707 on "SASplanet" database) and data started to go corrupt and missing.
Hard Drive is new.

Do you think SQL3 or Berkeley will work best?

Have you run BIG projects. Can you share your experience?

Yes, better use SQLite3. BTW, it became default cache type recently.
"Sasplanet" cache type stores each tile as a separate file, and if you download millions of them your file system would not be happy.

Just to reply to my own question:

The limit is how long your own partition structure or MasterBootRecord will stay redundant. Its all about the most number of files not amount of data.

SQLite3 default for the win.

When you go into zooms 20 or more then trouble may start again since data is stored by area (instead of tile strings), and you will have exponentially more areas.

But simple maths will tell you that you also require a volume bigger than 2TB, that is you will switch to 64bit and GPT partition (that also lets you restore data).

Well then, see you at the 64TB trouble :D

My SASPlanet cache is now around 1,5Tb and millions of files. :o
No way to convert stored "Sasplanet" cache into SQLite3 cache?

Of course you can do it: Operation - Cache Manager.
First try with some small cache, play around with parameters.
