 # :ddrt (README)
 
 A Dynamic, Distributed [R-Tree](https://en.wikipedia.org/wiki/R-tree) (__DDRT__) library written in Elixir. The 'dynamic' part of the title refers to the fact that this implementation is optimized for a high volume of update operations. Put another way, this is an R-tree best suited for use with spatial data _in constant movement_. The 'distributed' part refers to the fact that this library is designed to maintain a spatial index (rtree) across a cluster of distributed elixir nodes. 
 
 The library uses [@derekkraan](https://github.com/derekkraan)'s [MerkleMap](https://github.com/derekkraan/merkle_map) and [CRDT](https://github.com/derekkraan/delta_crdt_ex) implementations to ensure reliable, "eventually consistent" distributed behavior.
