I have a library I would like to submit for inclusion in Boost. This message is just soliciting for interest per the submission process. If interest is expressed, I'll carry on with a preliminary submission. The library is an embedded database, to the tune of products like the embedded version of InnoDB, BerkeleyDB, etc. In this case, the database is structured as a Boost.interprocess shared region (typically mmap so it can page) which contains one or more STL-like containers holding application defined data types in directly usable form (i.e. not serialized.) The database infrastructure is fully ACID compliant, with durability via write-ahead logging, and periodic checkpoints. More details, examples, and documentation is available at http://stldb.sourceforge.net/ for more details on this libraries capabilities. Currently, I've only implemented map<> (probably the most useful container type in a database), but the plan is to continue to add containers as requested/needed until ACID compliant versions of a decent portion of the STL are available. There are some concepts which I've been trying to flesh out with this, including a standard concept for a transaction-aware type which in turn exposes operations which can be logged, undone, recovered, etc. Allowing that concept to be used recursively (containers of other containers, or of application-defined transaction-aware objects) is one of the longer-term goals of this library. Let me know if there's any interest, and I'll work on a preliminary submission for the sandbox. Thanks, Bob Walters
