Abstract

U ovome radu su analizirane različite metode testiranja performansi vremenskih baza podataka. Također je obavljena prilagodba modela podataka sustava MeteoHOPS iz modela dimenzijskog skladišta podataka na model koji odgovara pohrani u vremenske baze podataka, Ti podaci su zatim pohranjeni u InfluxDB i TimescaleDB te je nad njima izvršeno testiranje performansi kako bi vidjeli koja vremenska baza više odgovara primjeni. Analiziran je unos podataka, zauzeće memorije te najčešći upiti koji predstavljaju usko grlo u radu MeteoHOPS sustava. Upiti su testirani pod jednokorisničkim i višekorisničkim opterećenjem.

Abstract (english)

This paper analyzes various performance testing methods for time-series databases. Additionally, a modification of the data model of the MeteoHOPS system was performed, transitioning from a dimensional data warehouse model to a model suitable for time-series database storage. This data was then stored in both InfluxDB and TimescaleDB, and performance testing was conducted to determine which time-series database better suits the application. Data input, memory usage, and the most common queries, which represent a bottleneck in the operation of the MeteoHOPS system, were analyzed. The queries were tested under both single-user and multi-user loads.
