Background
Command “c4 play” is used to deploy Exasol databases on different platforms (see Exasol Deployment Tool (c4)).
Previously, it was not possible to include reserve nodes into the default database deployed with “c4 play”.
New Feature
A new deployment parameter was added that allows configuring the default database that is created during deployment to use reserve nodes: CCC_PLAY_RESERVE_NODES.
It takes an integer for the number of nodes that should be reserve nodes.
The reserve nodes are part of the total number of nodes, so deploying with 4 nodes and CCC_PLAY_RESERVE_NODES=1 results in a DB with 3 active nodes and 1 reserve node.
