Great news and I am glad that GridGain was finally able to open source such an essential feature to Ignite. Given that I was deeply involved in the development of this feature for the past year, I would add that one of the main advantages here is that Ignite becomes fully operational from disk (SSD or Flash) without any need to preload the data in memory.
With full SQL support available in Ignite, this feature will allow Ignite serve as a distributed transactional database, both in memory and on disk, while continuing to support all the existing use cases, including the in-memory data grid. Cos, can you point us to any legal paperwork that needs to be signed in order to complete the donation? D.
