What’s New in Dragline (7.1.0): Resource Pool Routing

Resource Pool Routing from Vertica Systems on Vimeo.

HP Vertica 7.1.x introduces new features that allow you to dynamically reroute queries to secondary resource pools.

Use the new CASCADE TO parameter when creating or altering a resource pool to indicate a secondary resource pool to which queries can cascade and execute when they exceed the RUNTIMECAP of the pool on which they started running. This way, if a query exceeds its initial pool’s RUNTIMECAP, it can cascade to a designated secondary pool with a larger RUNTIMECAP instead of causing an error.

Because grant privileges are not considered on secondary pools, you can use this functionality to designate secondary resource pools where user queries can cascade to without giving users explicit permission to run queries on that pool.

Check out this video to learn more about dynamically rerouting queries.

What’s New in Dragline (7.1.0): Active Standby Nodes

Active Standby Nodes from Vertica Systems on Vimeo.

HP Vertica 7.1.x introduces active standby nodes.

An active standby node is a type of HP Vertica node that does not perform computations or contain data, but exists as a backup, ready to replace a node that’s failed. When the active standby node replaces the failed node, the active standby node performs all the calculations of the failed node.

As an example, imagine your database cluster as a team of basketball stars, working together to play a game. Normally, things go pretty smoothly. But what if one of your players gets injured? In basketball, it is likely that another team member, Read More »

What’s New in Dragline (7.1.0): Projections with Expressions

Projections with Expressions Video

Projections with Expressions from Vertica Systems on Vimeo.

HP Vertica 7.1 introduces the ability to use expressions with projections.

When you create a projection, you now have the option to use an expression as a column definition. For example, you can declare a column that sums two variables. When you load data into a projection with expressions, HP Vertica automatically calculates the values according to the expressions and inserts the data into that new projection. Once you create a projection with expressions, you can query the projection directly to access your pre-calculated data and eliminate resource-intensive computations at query time.

Backing Up and Restoring Your HP Vertica Database

Backing up and restoring your database is an important part of basic database maintenance. HP Vertica lets you create both comprehensive and object-level backups. This article highlights the HP Vertica 7.x features that enhance the backup and restore process.

Previously, you could not add nodes to your cluster between object-level backup creation and restoration. With HP Vertica 7.x, you can add nodes to the cluster after creating an object-level backup and then successfully restore the objects.

Another feature simplifies the mapping section of your vbr.py configuration file. When creating a backup, you create a configuration file that includes mapping sections that specify all database nodes included in the backup, along with the backup host and directory for each node. Previously, Read More »
