Custom database structure in C#
$500-1500 USD
着払い
This project requires exceptional coding skills about databasedesign. Concepts as shadowing, btrees should be familiar.
The intention of this file is to maintain thousands of small key-data pairs. In a later stage these files will be synchronised and will be used to maintain a distributed database.
*1.1* *Coding*
The coding should be in managed C#. Unsafe code is allowed, but only for performance reasons. A safe variant should be available to. This should be conditional.
*1.2* *Access*
This file does *not* have to allow multiple processes to access. It can be opened exclusive.
*1.3* *Multithreading*
Many threads within the same process will access the file. The file should be threadsafe
SingleWrite/Multiple read access is fine. I will not write much to the database.
*1.4* *OS*
I would like to be able to run this code on Pocket and normal PC’s.
*1.5* *Memory*
The file should try to keep memory requirements low. Some caching is allowed.
*1.6* *Transactions*
Data loss is acceptable, but only for the last changes. It is more important that the file doesn’t corrupt. Data is not highly sensitive or important.
File corruption is *not* an option.
Higher layer will handle with data loss.
