Python-LMDB In a High-Performance Environment
lkcl writes: In an open letter to the core developers behind OpenLDAP (Howard Chu) and Python-LMDB (David Wilson) is a story of a successful creation of a high-performance task scheduling engine written (perplexingly) in Python. With only partial optimization allowing tasks to be executed in parallel at a phenomenal rate of 240,000 per second, the choice to use Python-LMDB for the per-task database store based on its benchmarks, as well as its well-researched design criteria, turned out to be the right decision. Part of the success was also due to earlier architectural advice gratefully received here on Slashdot. What is puzzling, though, is that LMDB on Wikipedia is being constantly deleted, despite its "notability" by way of being used in a seriously-long list of prominent software libre projects, which has been, in part, motivated by the Oracle-driven BerkeleyDB license change. It would appear that the original complaint about notability came from an Oracle employee as well. -

Oracle Quietly Switches BerkeleyDB To AGPL
WebMink writes "A discussion in the Debian community reveals that last month Oracle quietly disclosed a change for the embedded BerkeleyDB database from the quirky Sleepycat License to the Affero General Public License (AGPL) in future versions. AGPL is only compatible with GPLv3 and treats web deployment as a trigger to license compliance, so developers using BerkeleyDB will need to check their code is still legally licensed. Even if they had made the switch in the interests of advancing software freedom it would be questionable to force so many developers into a new license compatibility crisis. But it seems likely their only motivation is to scare more people into buying proprietary licenses. Oracle are well within their rights, but developers are likely to treat this as a betrayal. As a poster in the Debian thread says, "Oracle move just sent the Berkeley DB to oblivion" because there are some great alternatives, like OpenLDAP's LMDB."
