As a part of
@CockroachDB#crdbfotw, here's a sneak peek at some enhancements coming to Cockroach Demo in the second 20.1 Alpha. Cockroach Demo will let you simulate killing a node! pic.twitter.com/H6ZPM1acJhPrikaži ovu nit -
In the webui, the dead node will show up as suspect (or dead after five minutes). We can then restart the node in the SQL shell to bring it back and address the unde-replicated ranges.

It's retail season & CockroachDB's serializable isolation keeps retail businesses safe. Weaker transaction isolation levels can create bugs that allow attackers to steal & corrupt inventory, as found in the infamous ACIDrain paper: https://cockroa.ch/35YLBut #crdbfotw@StanfordEng pic.twitter.com/iGw20kQ30P

CockroachDB supports row-oriented & column-oriented ("vectorized") query execution. Our vectorized execution engine improves performance for complex queries by processing each component of a query plan on type-specific batches of column data.

We taught our Cost-Based Optimizer to understand the physical location of
#data. Now it uses proximity to speed up#SQL query execution. It figures out a query's region, then only uses copies of data in the same region. Learn more https://cockroa.ch/31OgOhG#CRDBfotw@jessfraz pic.twitter.com/4ZlWfwpDsR

Security was a strong focus for us when we built CockroachCloud. All clusters are single-tenant (no shared machines) and run in a Virtual Private Cloud (no shared network) Read more about the security here: http://bit.ly/2W5Sczt #featureoftheweek#crdbfotw#DBaaS@RealGeneKim pic.twitter.com/h2Ms0NrI27

CockroachCloud lets you authorize the networks that can access your cluster. This helps prevent ""denial-of-service"" and ""brute force"" password attacks. Learn more about CockroachCloud's security features here: http://bit.ly/2PkXhTl #crdbfotw#featureoftheweek@ICooper pic.twitter.com/36DZALLBdG

CockroachCloud's security features include a combination of digital certificates and passwords. CA certificates are for client-to-node verification, while passwords are for #CockroachCloud-to-client verification. Learn more: http://bit.ly/2N63e3w#crdbfotw#featureoftheweek pic.twitter.com/EpZny6DXpK
