Hi Val, Thanks again for the response!
I guess the SpiQuery can help me part of the way potentially, but it doesn't give me the control to manage internal memory structure, replication, custom persistence etc. The Hazelcast API I am referring to is described in chapter 24 of the Hazelcast Manual (Extending Hazelcast - User Defined Services). This API was added when they released Hazelcast 3.0. As part of this release, they also rewrote all their internal data structures (e.g. Map, Queue etc) to use this same API so that you can write a service that can do anything their internal data structures can do. thanks, Gareth On Fri, Feb 12, 2016 at 4:54 PM, vkulichenko [via Apache Ignite Users] <ml-node+s70518n2992...@n6.nabble.com> wrote: > Hi Gareth, > > First of all, Ignite provides IndexingSpi interface [1] that you can > implement to support custom query language and custom indexing > implementation.
