Why are my Go executable files so large?
Golang executable files get too large for reasons that are not relevant to server software with long-running processes, like CockroachDB, and its incurred space cost is particularly inconvenient for large, feature-rich programs.

My Go executable files are still getting larger
The original draft of the analysis we presented was reviewed internally, and yet still inaccuracies slipped through. We are a team of humans. We make mistakes. We take full responsibility for the invalid conclusions we published.

How We Built a Vectorized SQL Engine
Using vectorized processing in an execution engine makes more efficient use of modern CPUs by changing the data orientation (from rows to columns) to get more out of the CPU cache and deep instruction pipelines by operating on batches of data at a time.

CockroachDB Stability Post-Mortem: From 1 Node to 100 Nodes
In August, we wrote about our concerted stability effort. Today, we've more than achieved our CockroachDB stability goal of running a 100-node cluster.

Stateful Apps on Kubernetes: A quick primer
Managing state in Kubernetes is difficult because the system’s dynamism is too chaotic for most databases to handle; especially SQL databases that offer strong consistency.

Antithesis of a One-in-a-Million Bug: Taming Demonic Nondeterminism
With the help of Antithesis, a startup from the founders of FoundationDB, CockroachDB engineers were able to track down and reproduce a most elusive one-in-a-million bug, nearly deterministically!

Why CockroachDB doesn't use EvalPlanQual
Under READ COMMITTED isolation, PostgreSQL can sometimes miss rows when performing UPDATE, DELETE, SELECT FOR UPDATE, or SELECT FOR SHARE statements. This is due to the EvalPlanQual recheck PostgreSQL adds to these statements to prevent lost-update anomalies.
