I have been using both Flux and InfluxQL recently, comparing which is faster and how to query using both efficiently. She will demonstrate how to install it, insert data, and build your first Flux query. Instead, the schema is automatically created from the input data, inferred from the tags and fields. InfluxDB works nicely with such user-case by adding numbers (in format "_###") to those keys. To configure InfluxDB, use the following configuration options when starting the influxd service: assets-path. The same principle as before remains.

We will be using Sysbench to run various tests to measure the CPU, Memory and File IO performance.. CPU. See these docs for details. As we can see, Flux returns 5 separate "tables", while InfluxQL just gives all the results together and mixed. The datastore provides a SQL-like language to query the data, called InfluxQL, which makes it easy for the developers to integrate into their applications. Then, since the field names are the same, they need to be renamed. Thanks, Graham InfluxQL supports type casting, but only for numeric data types (floats to integers and vice versa). ; stat_total_duration: Total duration to process the query. Flux.) Technology. During the development of RCB Cyclops it was paramount to design and optimise our database schema in order to achieve better than out-of-the-box performance - which was possible by combining InfluxData's design guidelines, as well as understanding our data records.InfluxDB lets you specify fields and tags, both being key/value pairs where the difference is that tags are automatically indexed. 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. comment reconnaitre une vraie doudoune jott; gilet jaquette mariage; lettre de motivation animatrice périscolaire mairie sans bafa Those joins, that are available in Flux without Kapacitor or Chronograf, don't work . Flux has an SQL package to help query from SQL data sources as well. 1 Answer.

Flux Open Source Query Language | InfluxData Let us look at the comparison table of Prometheus vs Influxdb, where we weigh both platforms based on different features. 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. 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. It also has a new custom query language called Flux, this language may make some tasks easier, but there is always a learning curve when adopting a custom query language. Right now, I do recommend to keep on using InfluxQL as Flux is not completely established in the platform.
