Apache Configuration Question

Type of Indices supported by Apache Ignite

In the documentation for Apache ignite, it states that they provide indexing functionality for RDDS.

Also in the below link we can find methods to create indices.
http://apacheignite.gridgain.org/docs/sql-queries

Is there any documentation on what kind of indices it supports underneath (B-trees, R-trees)

Answer

Ignite indexes are either based on SnapTreeMap [1] or on ConcurrentSkipListMap. The former is used for indexes stored in off-heap memory, while the latter is for on-heap.
