CockroachDBDuckDB
Specific characteristicsCockroachDB is a globally distributed, strongly and immediately consistent SQL data platform built to survive failures and scale out with minimal operational effort. It offers Distributed SQL with full ACID compliance on top of a transactional, Raft-replicated key-value store, supporting serializable transactions by default across the whole cluster. Its shared-nothing architecture with auto-sharding transparently splits data into small ranges that auto-rebalance as the cluster grows, so adding nodes increases capacity without requiring manual sharding/user intervention. CockroachDB is designed for multi-cloud and hybrid deployments, with a uniform SQL surface across all nodes so any node can accept reads and writes and all nodes can be joined into a single logical cluster across clouds or regions. ​Built-in disaster recovery and cross-cluster physical and logical replication options support active-active and standby architectures on cost-effective commodity infrastructure.
