Query: AstroServ: Distributed Database for Serving Large-Scale Full Life-Cycle
  Astronomical Data   In time-domain astronomy, STLF (Short-Timescale and Large Field-of-view) sky
survey is the latest way of sky observation. Compared to traditional sky survey
who can only find astronomical phenomena, STLF sky survey can even reveal how
short astronomical phenomena evolve. The difference does not only lead the new
survey data but also the new analysis style. It requires that database behind
STLF sky survey should support continuous analysis on data streaming, real-time
analysis on short-term data and complex analysis on long-term historical data.
In addition, both insertion and query latencies have strict requirements to
ensure that scientific phenomena can be discovered. However, the existing
databases cannot support our scenario. In this paper, we propose AstroServ, a
distributed system for analysis and management of large-scale and full
life-cycle astronomical data. AstroServ's core components include three data
service layers and a query engine. Each data service layer serves for a
specific time period of data and query engine can provide the uniform analysis
interface on different data. In addition, we also provide many applications
including interactive analysis interface and data mining tool to help
scientists efficiently use data. The experimental results show that AstroServ
can meet the strict performance requirements and the good recognition accuracy.
