Stacked Services [v5]

Stacked services are applications that are running on the same system, or node. Scuba consists of the following services that can be run on individual systems, or stacked on a single node:

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

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

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

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

  • String Node: The node with string storage for the active strings in the dataset, stored in compressed format. It requires sufficient memory to hold the working set of strings accessed during queries.

  • Listener Node: If applicable, streams live data from the web or cloud; also known as streaming ingest.
