Hi All,

Is there any good performance Key-Value storage engine written in free pascal, or can be linked with FPC application?

I need an embedded storage engine with good performance for a generic (non-binary) tree structure with the following properties and operations:

- tree node has 2 properties: data (byte array), and 0~N sub-nodes
- a fast way to iterate through all leaf nodes
- find parent, and parent of parent, until root
- get / iterate all siblings of a node (order is NOT important)
- insert node / set parent of a node
- cut-off or free (delete) a sub-tree

Thanks!

A new version 7.3 of the unit mpcalc has been released and can be downloaded from
http://www.polarhome.com/~franco/mpcalc-7.3.zip
or
http://spazioinwind.libero.it/frm/software/mpcalc-7.3.zip

Mpcalc provides multiprecision floating-point arithmetic up to 5000 digits. It includes a set of elementary functions and some special functions. I hope that it will be useful to someone.
In the package there is also a program to test the unit.

You are right. Thank you for pointing this, Sven.
I had some problem posting from polarhome (can't send).
