Hi, FYI, some ClickHouse expert are playing with our S15 benchmark (first node for now) https://clickhouse.yandex/ Regards De: "Vadim Tkachenko" <[log in to unmask]> À: "Bart Scheers" <[log in to unmask]> Cc: "Fritz Mueller" <[log in to unmask]>, "Fabrice Jammes" <[log in to unmask]> Envoyé: Lundi 4 Décembre 2017 16:39:39 Objet: Re: Re LSST Queries Bart, Thanks a lot! Fabrice, Fritz , would you make it possible to share the simulated data with the team that experts in ClickHouse? We also would be able to assist with ClickHouse questions if you have any. Thanks in advance, Vadim On Mon, Dec 4, 2017 at 5:54 AM, Bart Scheers < [ mailto:[log in to unmask] | [log in to unmask] ] > wrote: Hi Vadim, We ran the queries in ClickHouse as well, and will come with a report soon that we will share. As stated in the blog post the simulated data are generated by the LSST DM group and comes from the French LSST group at CNRS/LIMOS. They don't have any objections providing you with the data. But I'll have to refer you to them tp request the same s15 1.3 TB dataset. The one we used is named RegionOne. I'll forward you to Fabrice Jammes (LPC, Clermont-Ferrand, France) and Fritz Mueller (SLAC) who are in charge of the data. Recently we had been discussing the essence of having a representative set of LSST benchmark queries and the benefit LSST (as well as serious database systems) could make if they run these kind of queries. Could you keep me in the loop?
