About QuestDB
QuestDB was created in 2018 by Vlad Ilyushchenko and Nicolas Hourcard to address the need for a high-performance database capable of handling large volumes of time series data with low latency. It was developed to provide a scalable solution for industries requiring rapid data ingestion and real-time querying, such as finance and IoT.
Strengths of QuestDB include its high performance for time series data, SQL compatibility, and efficient handling of large datasets with low latency. Weaknesses may involve limited support for non-time series workloads and a smaller community compared to more established databases. Competitors include InfluxDB, TimescaleDB, and Apache Druid.
