the In-memory?
Can't all data be stored in DRAM?
If there is a technology that can store all data in DRAM, is indexing necessary?
DRAM Speed
DRAM reads/writes 1000 times faster than general storage media (SSD, HDD). In particular, Write is more than 10000 times faster. Implementation of scale-out to overcome the size limit of DRAM is absolutely required. Memory clustering technology between servers is required to implement scale-out.
