> Adding and searching objects in index tree produces a lot of garbage and this can lead to big GC pauses.
> Tests with data streaming of object with 5 string indexes show that ignite server spends about 15-25% CPU time in GC.
> The problem is that ignite deserialize objects for comparing, while for the primitive type and strings comparing can be implemented for bytes.
