Every Java-based backed service I have come across, be it ElasticSearch, LogStash, Hadoop or PuppetDB, have all been memory-hogging beasts. Part of this is due to the GC, which tends to use more heap space than the program actually needs. Java is fast, but I have yet to see anyone claim it's lightweight.

The worst part is "let's statically preallocate* the heap size like it's 1975".

*Note: never more than 31GB
