Growing cluster with new nodes


#1

Greetings, developers!

I really need to grow my SciDB (16.9) cluster with new nodes, and I am wondering if anybody faced same problem.

I have found several questions related to this topic ( Growing/Shrinking a cluster , Adding new nodes to scidb cluster ), but its all out of the scope due to old versions of SciDB.

Has anything changed? Is there any way to add a node to cluster easily?

Thanks!

Hi Yevgeniy

In the Enterprise Edition this is performed very easily - clusters can grow and shrink with minimal downtime. See https://github.com/paradigm4/elastic_resource_groups But this is an Enterprise Edition feature. Email info@paradigm4.com if interested.

In the Community Edition, you would have to export the data, start a larger cluster and then reload. Using a parallel backup in the “opaque” format would be fastest way to go.
