single node cluster has the following Scuba nodes installed on one device:

  • Config Node: The node from which you administer the cluster. MySQL database (DB) is only installed on this node for storage of Scuba metadata. Configure this node first.

  • API Node: The node that serves the Scuba application, merges results of queries from data and string nodes, and then presents those results. Nginx is only installed on the API node. 

  • Import Node: The node that polls data repositories (S3, Azure, local file system), downloads new files, processes the data, and then sends it to data and string tiers, as appropriate.

  • Data Node: The node responsible for data storage. This node must have enough space to accommodate all events and stream simultaneous query results.

  • String Node: String storage for the active strings in the dataset, stored in compressed format. Requires sufficient memory to hold the working set of strings accessed during queries.
