For a single threaded application BDB is very bad after I tested.
It takes nearly 2.5 times the amount of time and CPU to do a transaction of
40MB Data. E.g. If SQLIte did the 40MB data transaction (1 rows of 4 K)
in 1 second, BDB was taking 2.5 seconds and more CPU as well. I did this in
You use BDB SQL or BDB KV ?
You must try it with SQLightning too, https://gitorious.org/mdb/sqlightning

This is the BDB SQL doc I found.

If you insert record in bulk, you can use PRAGMA TXN_BULK for optimization.

Will SQLite4 be a better solution for me then ?
Also @aris do you recommend BDB over Sqlite for 1-10 Billion records ?

SQLite4 still in development phase. It is not production ready.

If you have many core of processors [and big RAM
SQLite do not use row level locking, but db level locking, so it was
the right behavior the second thread was blocked.
For innodb like in SQLite, Oracle have SQLite compatible API, but use
BDB backend.
Since BDB use MVCC (row/page level locking), your threads only blocked
if they will write in
, then test it before decide to use
it.
LMDB is storage engine optimized for read. Why you don't optimize it's
write using cache oblivious data structure, for example LSM tree or
create new, like in sophia (sphia.org) key value DB?

LMDB's codebase is still smaller and faster. Nothing else touches LMDB's
read
speed.
Focus to the write number.
You are using SSD or HDD?

Hi Durga,
Another alternative, you can use an xml database. It will fix your
problem easily using xquery, like this:
doc('region')//country/title/text() - it will show all region you have
Hi Durga,

doc('region')//country/title/text() - it will show all region you have
doc('region')//village/title/text() - it will show all village you have
You also can use selection
