I periodically need to make changes to tables… mostly adding columns. Very simple with the alter table command… But my tables have up to 40 million rows now and they are growing fast… So those alter table commands take several hours… Since I’m using amazon RDS [sic], I can’t have slave servers to play with and then promote to master. So my question is if there’s a way to do this with minimal downtime?
Cgo is an important part of Go: It's your window to calling anything that anything that has C bindings. But while cgo works for us, it hasn’t come for free.
In this post, we’ll share a few powerful optimizations that mitigate many of the performance problems common to Go garbage collection.
The first question many developers ask us is what our experience has been writing a distributed database in Go, a garbage-collected language.
For CockroachDB, the aim is to be highly scalable and transactional. We asked them to share technical details of their open source, distributed SQL database
SQL? I thought CockroachDB was a key-value store?!? In the past we described CockroachDB as a distributed, transactionally consistent, key-value store.
One of the headline features of CockroachDB is its full support for ACID transactions across a distributed database. In this post, we’ll explain...
In CockroachDB, we use the Raft consensus algorithm to ensure that your data remains consistent even when machines fail.
Today, we’re launching CockroachDB for everyone. Use it. Build on it. Contribute to it!
