IndexTank is now open source! by Diego Basch, Director of Engineering, LinkedIn.
From the post:
We are proud to announce that the technology behind IndexTank has just been released as open-source software under the Apache 2.0 License! We promised to do this when LinkedIn acquired IndexTank, so here we go:
indextank-engine: Indexing engine
indextank-service: API, BackOffice, Storefront, and NebulizerWe know that many of our users and other interested parties have been patiently waiting for this release. We want to thank you for your patience, for your kind emails, and for your continued support. We are looking forward to seeing IndexTank thrive as an open-source project. Of course we’ll do our part; our team is hard at work building search infrastructure at LinkedIn. We are part of a larger team that has built and released search technologies such as Zoie, Bobo, and just this past Monday, Cleo. We are excited to add IndexTank to this array of powerful open source tools.
