	Funding: National Research Foundation (South Africa) Data indexed by time is continuously collected from instruments, environment and users. Samples are recorded from sensors or software components at specific times, starting as simple numbers and increasing in complexity as associated values accrue e.g. status and acquisition times. A sample is more than a triple and evolves into a document. Besides variance, volume and veracity also increase and the time series database (TSDB) has to process hundreds of GB/day. Also, users performing analyses have ever increasing demands e.g. in <10s plot all target coordinates over 24h of 64 radio telescope dishes, recorded at 1Hz. Besides the many short-term queries, trend analyses over long periods and in-depth enquiries by specialists around past events e.g. critical hardware failure or scientific discovery, are performed. This paper discusses the solution used for the MeerKAT radio telescope under construction by SKA-SA in South Africa. System architecture and performance characteristics of the developed TSDB are explained. We demonstrate how we broke the mould of using general-purpose database technologies to build a TSDB by rather utilising technologies employed in distributed file storage.

TUPHA049	ARES: Automatic Release Service	ion, software, controls, framework	503
	I. Prieto Barreiro, F. Varela CERN, Geneva, Switzerland
	This paper presents the Automatic RElease Service (ARES) developed by the Industrial Controls and Safety systems group at CERN. ARES provides tools and techniques to fully automate the software release procedure. The service replaces release mechanisms, which in some cases were cumbersome and error prone, by an automated procedure where the software release and publication is completed with a few mouse clicks. ARES allows optimizing the time and the work to be performed by developers in order to carry out a new release. Consequently, this enables more frequent releases and therefore a quicker reaction to user requests. The service uses standard technologies (Jenkins, Nexus, Maven, Drupal, MongoDB) to checkout, build, package and deploy software components to different repositories (Nexus, EDMS), as well as the final publication to Drupal web sites.
