When importing the OpenStreetMap data for Germany, with this feature in place we found that the DynamicStringStore was now 80smaller than before! Not only that but time for reading and writing strings had improved by at least 25! (the benchmark I got this from creates nodes and relationships as well, so pure string operations is probably even faster)
Disk space and RAM getting cheaper doesn’t mean you should waste it.
Redis is also obsessed with optimizing the space used by its data structures. HBase is recommending using LZO compression.
