For example, take the following two columns and their Extent Map information:. InfiniDB supports different operation mode. However, for many data warehousing, data mart, and analytic database tasks, the open source version of InfiniDB provides plenty of power to plow through big databases. Extent elimination is first accomplished in InfiniDB via the column-oriented architecture only needed columns are scanned , but the process is accelerated because of this logical horizontal partitioning that is implemented in the Extent Map. The company developed InfiniDB , a scalable, software-only columnar database management system [2] for analytic applications. In distributed mode, InfiniDB supports hash join and merge sort join.

Database of Databases – InfiniDB

From Wikipedia, the free encyclopedia. Yes, working with big databases is not a lot of fun. Existing customers may be able to receive support from other companies, notably MariaDB. It also automatically marks a join as semi join if it is applicable.

InfiniDB supports different operation mode. Retrieved January 17, InfiniDB’s column-store architecture enables very quick load and query times.

To eliminate an extent when a column scan involves a filter, that filter value is compared to the minimum and maximum values stored in each extent for the column:. We are always looking for interesting articles about MySQL! But now there are infinid number of column-oriented databases that are really taking off, however most still are proprietary and cost quite a bit. The end result is the ability infijidb interrogate and return query results against either moderate or large amounts of data in a pretty darn efficient manner.


InfiniDB can be infjnidb to run in different operation modes. Any column with clustered values is a good candidate for extent elimination. It can be configured by the administrator. This automatic extent elimination behavior is well suited for time-based data where data is loaded frequently and often referenced by time. Lately, the idea of column-oriented databases has been catching new wind in its sails.

InfiniDB System Properties

One interesting feature that allows InfiniDB to handle lots of data is a structure called the Extent Map. On system crashes, those logs can be replayed with Version Buffer, which stores information about all inrinidb transactions.


I could quote a lot of industry statistics and TDWI reports on this fact, but that would just bore you because you likely know all this stuff already.
