The relational database PostgreSQL (also known as Postgres) has grown increasingly popular, and enterprises and public sectors use it across the globe. With this widespread adoption, databases have become larger than ever. At Crunchy Data, we regularly work with databases north of 20TB, and our existing databases continue to grow. My colleague David Christensen and I have gathered some tips about managing a database with huge tables.
=> ↺ Replacing postfix with dma
I like Postfix. I’ve been a fan of it for over 20 years. I deployed it on every host for outgoing email. Lately, I’ve taken to using dma (DragonFly Mail Agent) as my preferred mail handler on jails and hosts which don’t need to deal with incoming mail, only outgoing mail. After first getting serious with it about 6 months ago, I decided to remove it from all internal hosts during the consolidation of two hosts into one.
=> ↺ Troubleshooting the other half
You should know the operational state of your network because there really is no reason why you should not. The IETF and your hardware vendor of choice have worked hard to give you a whole fleet of protocols and machinery to assess all aspects of the pieces of the Internet that are under your direct control. But once you leave your own network and enter the public Internet, there is hardly anything you can do to pinpoint potential problems. And you might argue that nobody other than the network operator in question should actually be able to do that. Well, people using vital infrastructure hosted in the cloud might disagree.
=> ↺ Future Internet PKI schemes need to be bootstrapped through web PKI
A core element of any public key infrastructure (PKI) is identifying things, because by themselves public keys are relatively useless; you care about using public keys to talk to something or authenticate some information, and for that you need to know who you're talking to or who is giving you this information. Identifying things on the Internet can sound simple ('root of trust' everyone says in chorus) but it turns out to be very hard to do in practice in the face of attackers, misaligned incentives, mistakes, and other issues. There is exactly one Internet PKI system that is solving this problem in practice with a demonstrated ability to operate at scale and despite problems, and that is public web TLS.
