+A working project for High-concurrency B-tree source code in C. You probably want to download threadskv8.c for the latest developement version.
Here are files in the btree source code:
threadskv5.c Multi-Threaded/Multi-Process based on threadskv4b that supports bi-directional cursors through the btree. Also supports raw disk partitions for btrees.
+threadskv6.c Multi-Threaded/Single-Process with traditional buffer pool manager using the swap device. Based on threadskv5 and btree2u.
+
+threadskv7.c Multi-Threaded/Single-Process with atomic add of a set of keys under eventual consistency. Adds an individual key lock manager.
+
+threadskv8.c Multi-Threaded/Single-Process with atomic-consistent add of a set of keys based on threadskv6.c. Uses btree page latches as locking granularity.

Compilation is achieved on linux or Windows by:
-gcc -D STANDALONE threads2h.c -lpthread
+gcc -D STANDALONE -O3 threadskv8.c -lpthread
