I've found databases typically come in two flavors, your traditional row-oriented RDBMS or an object oriented database (OODBMS). However, in the mid 90s I remember, a new breed of databases showing up that were column oriented. Some of these were given the term 4GL, but I don't think it was a term that stuck. What I'd like to know is ...
preferably open source for storing tick info. ...
Will a column-oriented storage engine (e.g. InfiniDB) be available in the core release of MySQL 5.5? Meaning, not as a plugin but available with the core MySQL 5.5 bundle. ...
Although I have Java in the title, this could be for any OO language. I'd like to know a few new ideas to improve the performance of something I'm trying to do. I have a method that is constantly receiving an Object[] array. I need to split the Objects in this array through multiple arrays (List or something), so that I have an independ...
The more I read about NoSQL, the more it begins to sound like a column oriented database to me. What's the difference between NoSQL (e.g. CouchDB, Cassandra, MongoDB) and a column oriented database (e.g. Vertica, MonetDB)? ...
I've seen two contradictory pieces of advice when it comes to designing row IDs in HBase, (specifically, but I think it applies to Cassandra as well.) Group keys that you'll be aggregating together often to take advantage of data locality. (White, Hadoop: The Definitive Guide and I recall seeing it on the HBase site, but can't find it....
I have checked different column-oriented database systems such as InfiniDB, InfobrightDB and MonetDB. None of them support unsigned integers as a data storage type. Why? One solution is to store all 4 byte unsigned integers into 8 byte signed integers (Link), however I think it would waste too much space. Is there any open-source column ...
