Note, that 10,000 is not an upper limit, but just an official recommendation. Use sort() to order records within each table by specific columns and limit() to limit the number of records in output tables to a fixed number, n. InfluxDB 3. After the fields were parsed and cleaned, they arrived in InfluxDB, ready to be queried. All InfluxDB data is stored in a bucket. Limits include: Write request limits: 50 MB maximum HTTP request batch size (compressed I would like InfluxDB to have a configuration setting to limit the number of concurrent compactions. Use the following guidelines to determine which to use: If setting a column value to a predefined, static value, use set() or experimental. 8 dont use FIRST() or LAST() if you have not GROUP BY because its very slow:(So if you want to get the these Values you shoud use: but it's about SLIMIT (Series Limit). range() filters rows based on time bounds. This is set to 10,000 by default and can be configured by modifying max-row-limit in the http section of the configuration file. Table and column limits. org and orgID are mutually exclusive. I suggest you change your database architecture by writing values into different value fields. Use LIMIT to limit the number of rows returned per InfluxQL group.

After all, it is the best to check it empirically, particularly on your hardware. As a workaround, use LIMIT in your query to get the first timestamp and use a combination of ORDER BY time DESC and LIMIT to get the last timestamp: First timestamp: > SELECT usage_idle FROM cpu WHERE cpu='cpu-total' LIMIT 1 name: cpu ----- time usage_idle 2016-04-11T17:36:30Z 97. max-row-limit = 0. set(), and map can each set columns value in data, however set functions have performance advantages over map(). max-connection-limit. I store multiple field values per DB-entry and reassemble those rows with pivot(). InfluxDB includes a "partial":true tag in the response body if query results exceed the max-row-limit setting. The current usage plans mention that you can create an unlimited number of buckets. Export a dashboard variable in the InfluxDB user interface. Use set() instead of map() when possible.
