I am having similar issues setting up the same source using the "InfluxQL" Query Language option, following the InfluxDB Grafana with InfluxQL guide. See this tutorial for details. InfluxDB data source options differ depending on which query language you select: InfluxQL or Flux. Environment: Grafana version: v7.4.5 (8a2c78d) Data source type & version: InfluxDB Flux (InfluxDB 2.0.4) running as docker container Instead, the schema automatically created from the input data, inferred from the tags and fields. Cast boolean field values to integers The improvements yield a 50% write performance boost under load, allowing users to rapidly store even more data than before. In the query I select: 5 measurements 20 fields time range from 2019-01-01 up to 2021-09-11 with 15 minute points VictoriaMetrics doesn't support InfluxQL or Flux but provides a better query language - MetricsQL. This data should prove valuable to developers and architects evaluating the suitability of these . InfluxDB eventually adopted Flux as a query language to interact with data. Setup tasks (pka Continuous Queries) to handle downsampling. There are some in Flux, but they use rare tools, Kapacitor or Chronograf. The main differences between v1.7 and v2.0. InfluxDB originally started with a language similar to SQL called InfluxQL, which balanced some aspects of SQL with custom syntax. That approach will also make it possible for InfluxDB to natively support SQL . - initial performance is there but it turns into slow performance over time. New query languages introduce significant overhead, reduce readability, force a greater learning curve onto new users, and possess a scarcity of compatible tools. Benchmarking TimescaleDB vs. InfluxDB 6 Query language summary While Flux may make some tasks easier, there are significant trade-offs to adopting a custom query language like it. InfluxData. The InfluxDB IOx project is written in the Rust programming language and incorporates Apache Arrow, an open source in-memory analytics engine that incorporates a columnar data store that is being advanced under the auspices of the Apache Software Foundation (ASF).

Let us look at the comparison table of Prometheus vs Influxdb, where we weigh both platforms based on different features. Click Data. ; query: The textual representation of the query. Kapacitor is a powerful tool, if you need more power use it. I noticed a pretty significant difference in performance between Flux and InfluxQL and was wondering if there is an explanation for it. I have been using both Flux and InfluxQL recently, comparing which is faster and how to query using both efficiently. 1 Answer. I have been using both Flux and InfluxQL recently, comparing which is faster and how to query using both efficiently. Working with time series is possible in many different languages like InfluxQL, PromQL, Flux, and others. InfluxDB 2 - database element for your metrics 02. This InfluxQL call on a 1.8 runs in less than a second: SELECT last("Value") AS "mean_Value" FROM "MonitoringDB"."autogen . Insert performance The emergence of NoSQL as a popular paradigm has effectively split databases into two categories: SQL and NoSQL. Flux.) I too have noticed significant performance regressions with Flux and InfluxDB OSS 2 GA releases when compared to like queries in InfluxQL, or indeed with the same Flux queries running on the InfluxDB OSS 2 Beta versions before the storage engine was reverted to the 1.8 version. Query performance Flux vs InfluxQL I compared the performance of Flux and InfluxQL by querying exactly the same data. Include option to show detailed logs for Flux queries, including the following log fields: compiler_type: Compiler used for processing the query (will always be Flux). We'll continue to optimize for that while also optimizing performance, stability, the overall ecosystem and our community. As we can see, Flux returns 5 separate "tables", while InfluxQL just gives all the results together and mixed. The performance can be up to 100 times worse compared to a similar InfluxQL statement in 1.8. The difference amounts to this: compared to the SQL relational algebraic model, the flow-based functional model in Flux provides greater control to the user, but at the cost of reducing the power. Beside the article start by stating that they rebranded their product influxQL > Flux precisely because power user found major lacking features as to compare with SQL. InfluxQL query language. InfluxDB works nicely with such user-case by adding numbers (in format "_###") to those keys. Backward compatibility with the endpoints /query and /write for existing tools (Grafana) using authenticated users 1.x (InfluxQL queries, TickScript).
