Likelihood to Recommend Paired with Citect SCADA or System Platform, this is an excellent process historian. It also works well collecting OPC data. For basic data storage, retrieval, and analysis, this is well suited. This is not well suited for very large deployments. Multiple instances would need to be used to scale up, and the data fed into a second-tier/enterprise historian for corporate user consumption.
Read full review QuestDB is well suited for any use case where you need to store large amount of data and the performance is the key factor - for both reads and writes. So use cases like market data storage in financial industry, any kind of telemetry, etc.
Read full review Pros Data storage--multiple data sources stream data in real time; it is stored without issue Data retrieval--small to moderate queries and trends are generally fast and efficient Cost effectiveness--it is one of the cheaper (non-enterprise) historian offers and therefore is good value for money (with a reduced feature set) Read full review Extreme performance. Super easy to use. Compatibility with Influx line protocol. PostgreSQL compatibility. Out of order timestamps. Support for multiple records with same timestamp. Integration with Grafana. Team responsiveness. Read full review Cons Query performance--for very long-term/large queries; the latest version which we are yet to commission has some improvements in this area User interface--the trend, query, and Excel add-ins are basic and could do with a refresh; web-based clients are a paid add-on and less full featured, so not a true replacement Connectivity--Wonderware System Platform driver packs are required for additional data source types, where native connectors are not provided by other products Read full review New project so needs a bit polishing. Read full review Alternatives Considered AVEVA Historian, formerly Wonderware, was the best of the process tier historians in terms of reliability and functionality. It is still under development and not a "dead" product. It is also more cost effective than the more full-featured enterprise historians, such as PI, which our organization is not yet ready for. The feature set is at the right cost level, coupled with current support, were the key factors in the decision.
Read full review We were looking for time series database that will be able to handle L2 market data and came across QuestDB. From the beginning we were impressed how well the QuestDB performs and that it actually significantly outperforms all other open source TSDB on market like
InfluxDB ,
ClickHouse ,
Timescale , etc. Apart from the excellent performance it is also super easy to use and deploy which makes the experience of using the database very pleasant - we were able to be up and running and storing data within few hours. Topic itself is the QuestDB team that is super responsive on their slack channel and always ready to help with any query. They are constantly improving the product and if there is some missing feature that is blocking you from usage they always try the best to implement such feature asap and release a new version - one of the best support I have ever seen so far in open source community.
