Last week at the CHAR(10) conference we had a workshop on “Cloud Databases”. To put it simply: what to do when the use case requirements exceed the resources available in the database server. This was a main topic of the whole conference, and several solutions have been illustrated during the day. A common theme has […]
This week I did something I’d prefer to never repeat: I left the country, did something useful, and made it back again in the same day. The occasion was the FreeBSD Developer Summit, held just before BSDCan–the convention that happens in Ottawa the week before PGCon every year. So I get to head right back […]
If you have a Linux server of the RedHat family (inclusing CentOS and Fedora), you might envy the way Debian/Ubuntu distributions handle PostgreSQL clusters management. Although it is not easy to install different PostgreSQL versions on the same RedHat Linux server using RPMs, it is much simpler to install several instances of PostgreSQL (servers) and, […]
If you’re running Linux, and particularly if you’re running a database on Linux, it’s been hard to recommend any filesystem other than plain old ext3 in recent years. Some of the alternatives that looked interesting at one point–jfs, ReiserFS–are completely abandoned at this point. The one that has been almost viable for some time now […]
A few weeks ago I presented an updated 2010 version of my talk on database hardware benchmarking at PG East. CPU and memory performance are particularly important for a PostgreSQL database, because every individual query runs as a single process. Therefore, the speed of your fastest core determines how fast any one query can execute […]
I have been thinking for a while now about adding Greenplum support to an open-source application for web analytics that I wrote a few years ago, which is called htMiner and uses PostgreSQL. In order to do this, I need a multi-CPU environment. While still waiting to get our new servers installed here in our […]
Today is the deadline for the special room rate at the hotel hosting this month’s PostgreSQL Conference East 2010. If you’ve been procrastinating booking a spot at the conference, as of tomorrow that will start costing you. My talk is on Database Hardware Benchmarking and is scheduled for late afternoon on the first day, Thursday […]
The new Hot Standby feature in the upcoming PostgreSQL 9.0 allows running queries against standby nodes that previously did nothing but execute a recovery process. Two common expectations I’ve heard from users anticipating this feature is that it will allow either distributing short queries across both nodes, or allow running long reports against the standby […]
Due to the weather related travel issues this week, the launch party we had planned for this Friday has been canceled.
Checkpoints can be a major drag on write-heavy PostgreSQL installations. The first step toward identifying issues in this area is to monitor how often they happen, which just got an easier to use interface added to the database recently.
