Dear Wiki user, You have subscribed to a wiki page or wiki category on "Lucy Wiki" for change notification.
The "LucyIncubatorProposal" page has been changed by MarvinHumphrey. http://wiki.apache.org/lucy/LucyIncubatorProposal?action=diff&rev1=23&rev2=24 -------------------------------------------------- Marvin Humphrey has a great job at Eventful working primarily on this project and supporting applications that use it. Nevertheless, he is extremely dedicated to Lucy and is determined to see it through to the point where it becomes self-sustaining, regardless of work circumstances. === Relationships with Other Apache Products === + Lucy's relationship with Lucene of cordial "coopetition" has produced benefits for Lucene users in terms of indexing speed, near-real-time search support, and more. We expect the projects to continue diverging and converging over time as innovations migrate back and forth, with happy results for all involved. - When Lucy was conceived, we envisioned that our eventual sub-communities (Perl, Ruby, etc) would approach using and extending the library in distinct ways, and that we would be able to harness the creative tension between the different cultures to drive innovation. Lucy and Lucene have that kind of a relationship today, and multiple significant novelties have either cross-pollinated or arisen while discussing competing approaches. (e.g. object conservation during indexing, per-segment search.) - - Still, Lucy is a loose port and its core differs in fundamental ways from that of Lucene. The biggest difference is that for Lucy, "the OS is our JVM": Lucene Searcher objects build up optimized data structures at search-time in process RAM, while Lucy writes its data structures to disk at index-time and reads them via memory-mapped IO at search-time. This affords Lucy several advantages, such as fast process launch, low process RAM requirements, and OO design flexibility because Lucy's "cheap Searcher" objects are lightweight, thin wrappers around the system IO cache. === An Excessive Fascination with the Apache Brand === Our desire to maintain Lucy's affiliation with Apache has much less to do with the brand and much more to do with our conviction that developing the project The Apache Way under Apache institutions is in Lucy's best interests. However, we have to acknowledge that during its time as a Lucene subproject, Lucy has not always fulfilled certain key requirements for an Apache project. In particular, it has failed to "release early, release often", and it has made only limited progress in expanding its community.
