CockroachDB 20.2 has demonstrated a 40% improvement in performance on the TPC-C benchmark compared to its previous version, 19.2. The latest release can handle up to 140K warehouses with a maximum throughput of 1.7M transactions per minute (tpmC). This enhancement was achieved due to faster bulk data loading and more efficient foreign key checks and lookup joins. CockroachDB's performance improvements allow customers to manage larger workloads on their clusters, leading to cost savings.
