YugabyteDB's sharding, replication, and transactions architecture is similar to CockroachDB in that both are inspired by the [Google Spanner design paper](https://research.google.com/archive/spanner-osdi2012.pdf). Additionally, both use Raft as the distributed consensus replication algorithm and RocksDB as the per-node storage engine. The following sections highlight the advantages and similarities YugabyteDB has when compared with CockroachDB.

## Advantages

YugabyteDB beats CockroachDB in the context of multiple developer benefits including higher performance for large data sizes, better PostgreSQL compatibility, more flexible geo-distributed deployment options as well as higher data density. Following blogs highlight the architectural and implementation advantages that make these benefits possible.
