Superior to traditional active-passive and active-active system, CockroachDB™ enables all replicas to handle traffic while ensuring the data consistency by using “consensus replication”. As long as a majority of replicas can talk to each other, the cluster is available.
Thanks to the strongly-consistent replication and powerfully automated repair ability, CockroachDB™ successfully survives the software and hardware failures in whatever a short or a long term, from a server restart to a datacenter outage.
CockroachDB™ distributes transactions across clusters, which can span regions, data centers, and cloud providers. Data can dynamically move wherever necessary without compromising down-time or additional latency.
As an open-source programming language supporting libraries, interfaces, and tooling, Go is a right choice for CockroachDB™, helping build an excellent performance and distributed system while ensuring high speed and stability.
CockroachDB™ replicates data multiple times and guarantees consistency between nodes. It guarantees the SQL isolation level 'serializable' by combining the Raft consensus algorithm for writes and a custom time-based synchronization algorithms for reads.
With the implementation of Standard SQL and extensions, CockroachDB™ makes it possible to write familiar queries. Its support for PostgreSQL wire protocol significantly facilitates the application’s talk to CockroachDB™.
CockroachDB™ automatically scales, rebalances, and repairs itself. When data flow in to a threshold, a range will be split into new ranges, which will be automatically rebalanced to nodes with more capacity if your cluster spans multiple nodes.
Simplicity is a top priority in the design of CockroachDB™. Its nodes are self-organized and symmetric, perfectly realizing a homogeneous deployment with minimal configuration and zero external dependencies.
