influxql vs flux performance
2023-10-10

Index versions and startup times. In the query I select: 5 measurements 20 fields time range from 2019-01-01 up to 2021-09-11 with 15 minute points I noticed a pretty significant difference in performance between Flux and InfluxQL and was wondering if there is an explanation for it. influx -type = flux -username myuser -password . InfluxDB OSS exposes a /metrics endpoint that returns performance, resource, and usage metrics formatted in the Prometheus plain-text exposition format. InfluxQL re-written. Thanks, Graham Playing with Flux, a data scripting language - Medium The difference here is often in the range of single-digit to double-digit milliseconds. Your specified flux query would work if itemType was a tag, however, since it is a field one of the ways to make the query work is by setting conditions on the field name and its value as follows: from (bucket: "dbname/autogen") |> range (start: 2020-10-12T01:56:34Z, stop: 2020-10-12T02:54:10Z) |> filter (fn: (r) => r._measurement . 1 Answer. 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. The emergence of NoSQL as a popular paradigm has effectively split databases into two categories: SQL and NoSQL. I switch to using FLUX queries instead of InfluxQL so that I can . 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). Convert InfluxQL Queries to Flux using the Transpiler. TimescaleDB vs. InfluxDB: purpose built differently for time ... - Medium InfluxQL can only query data stored in InfluxDB. InfluxDB is meant to be used as a backing store for any use case involving large amounts of . InfluxDB is a noSQL open source time series database built by InfluxData and written in Go. In contrast, InfluxDB began with a "SQL-like" query language (called InfluxQL), placing it in the middle of the spectrum, and then made a marked move towards the "custom" end with a new query language from InfluxDB called Flux. InfluxDB OSS metrics | InfluxDB OSS 2.2 Documentation Flux can query data from other data sources such as CSV, PostgreSQL, MySQL, Google BigTable, and more. Notation The syntax is specified using Extended Backus-Naur Form ("EBNF"). Optimize writes to InfluxDB | InfluxDB OSS 2.2 Documentation Attempting to put together a API performance test pipeline. InfluxQL supports type casting, but only for numeric data types (floats to integers and vice versa). See this tutorial for details. I have been using both Flux and InfluxQL recently, comparing which is faster and how to query using both efficiently. Benchmark flux vs. influxql performance with multiple measurement ... We'll continue to optimize for that while also optimizing performance, stability, the overall ecosystem and our community.
