With DRAM price this high, this is certainly a welcome feature. But how do you control write latency? B+ Tree is pretty bad at updates and LMDB, another BTree based storage is lightning fast on reads but quite bad on writes compared with RocksDB.

The disk storage EloqKV uses (EloqStore [1]) is optimized for batch updates because the upper Data Substrate layer manages buffering and the Write-Ahead Log (WAL), absorbing writes and guaranteeing durability. When durability is not required, the WAL can be optionally disabled.

we leverage batch write optimization which uses Copy-on-write B-tree variant enables high-throughput batch writes without blocking concurrent reads. MVCC-based design eliminates lock contention and provides predictable write amplification.
