The first production version of Dolt was released a little over a year ago. Since then we have been narrowing the performance differences between MySQL and Dolt. We've blogged several times recently about…

Now that Dolt supports Dolt-to-MySQL replication, it's easy to set up Debezium to monitor data changes on a Dolt branch.

The inspiration for Dolt and DoltHub was data sharing. Most data today is shared via file. Common data formats are CSV, XML, or JSON. Dolt is a fully capable MySQL-compatible SQL database with Git-like version…

How running bats tests with massive parallelism using AWS Lambda speeds up our CI and local iteration cycle

What open source database is faster? Postgres or MySQL? It's surprisingly hard to find latency benchmark comparisons between these two databases. Here at DoltHub, we're building the world's first version co…

We use Prolly Trees to unlock fast version control of JSON documents just like we do with tables.
