+## 08.11.2022 Intro to QuestDB Time Series Database
+
+**Speaker** Javier Ramirez (https://es.linkedin.com/in/ramirez)
+
+**Abstract** Time Series forecasting and modelling is fun, but capturing time-series data and dealing with large volume datasets not so much.
+In this talk we will introduce QuestDB, an Apache 2.0 licensed database specialised in time-series. We will see how QuestDB can help ingesting, interactively querying, downsampling or augmenting your data. Since QuestDB is postgreSql-compatible, we can interact easily using python with or without Pandas. We will run a demo using QuestDB and skforecast to illustrate how QuestDB can be integrated to your data science workflows.
