Hi, Use metrics to see what data regions are using off heap. https://apacheignite.readme.io/docs/iodataregiondata_region_name
A small index should not consume that much memory. Try turning on persistence to see exactly how large your index.bin files are. https://apacheignite.readme.io/docs/distributed-persistent-store. see: https://cwiki.apache.org/confluence/display/IGNITE/Ignite+Durable+Memory+-+under+the+hood and https://cwiki.apache.org/confluence/display/IGNITE/Ignite+Persistent+Store+-+under+the+hood Use experimental means to determine what is taking off heap. Clear out your data and re-load a small amount, note how the off heap grows, load more data. Try loading the data with and without an index.
