What is the default retention policy for InfluxDB?
When you create a database in InfluxDB, you automatically create a default retention policy for that database called autogen. If you choose not to modify the default policy, the value is set to infinite. In this case, the shard group duration will default to 7 days.
What is retention policy in InfluxDB?
A retention policy (RP) is the part of InfluxDB data structure that describes for how long InfluxDB keeps data. InfluxDB compares your local server’s timestamp to the timestamps on your data and deletes data that are older than the RP’s DURATION . A single database can have several RPs and RPs are unique per database.

How is time stored in InfluxDB?
InfluxDB stores all timestamps as nanosecond values, regardless of the write precision supplied.
Is there any GUI for InfluxDB?
The built-in web administration GUI is deprecated in InfluxDB 1.2 and is disabled by default. We recommend using the HTTP API or the Command Line Interface to interact with InfluxDB.
What is Autogen InfluxDB?
When you create a database, InfluxDB automatically creates a retention policy called autogen with an infinite duration, a replication factor set to one, and a shard group duration set to seven days.
What is a shard in InfluxDB?
A shard contains encoded and compressed time series data for a given time range defined by the shard group duration. All points in a series within the specified shard group duration are stored in the same shard. A single shard contains multiple series, one or more TSM files on disk, and belongs to a shard group.
How do you create a retention policy?
- Navigate to Compliance management > Retention policies, and then click Add.
- In New Retention Policy, complete the following fields: Name: Enter a name for the retention policy. Retention tags: Click Add. to select the tags you want to add to this retention policy.
What is a series InfluxDB?
In InfluxDB, a series is a collection of points that share a measurement, tag set, and field key.
How do you clean InfluxDB?
- Use the influx delete command to delete points from InfluxDB.
- Use the –bucket flag to specify which bucket to delete data from.
- Use the –start and –stop flags to define the time range to delete data from.
Do I need time series database?
Time series databases enable faster data ingest and queries and stronger data compression. As a result, they are ideal for processing massive volumes of real-time data that can be used to improve the safety of self-driving cars.
Why do I need a time series database?
Time series data is often a continuous flow of data like measurements from sensors and intraday stock prices. A time-series database lets you store large volumes of timestamped data in a format that allows fast insertion and fast retrieval to support complex analysis on that data.
How many series can InfluxDB handle?
If your InfluxDB performance requires any of the following, a single node (InfluxDB OSS) may not support your needs: more than 750,000 field writes per second. more than 100 moderate queries per second (see Query guides) more than 10,000,000 series cardinality.

What is chronograph InfluxDB?
Chronograf allows you to quickly see the data that you have stored in InfluxDB so you can build robust queries and alerts. It is simple to use and includes templates and libraries to allow you to rapidly build dashboards with real-time visualizations of your data.

What port is InfluxDB on?
By default, InfluxDB uses the following network ports: TCP port 8086 is available for client-server communication using the InfluxDB API. TCP port 8088 is available for the RPC service to perform back up and restore operations.
What is Autogen retention policy?
Retention Policies are unique per database. When a database is created, the default is autogen with an infinite duration, a replication factor of 1, and a shard group duration of 7d (7*24=168h). shard group has a retention policy and shard group duration(window of time each shard group spans ).
How much data can InfluxDB handle?
InfluxDB suggest up to 250K writes / second with 25 queries per second on up to 1M unique queries is feasible on a single node. See hardware guidelines. For the amount of data you have single node is more than enough – size of data does not matter, number of series does.
Does InfluxDB compress data?
InfluxDB uses multiple compression techniques which vary depending on the data type of the field and the precision of the timestamps. Timestamp precision matters because you can represent them down to nanosecond scale.
What is Wal InfluxDB?
The WAL is where incoming writes hit initially. As I mentioned before, this is a “write optimized” file structure that allows writes to be appended to the file. These writes are also maintained in an in-memory cache to support querying.
What is Shardgroupduration?
The shard group duration specifies the time range for each shard group and determines how often to create a new shard group.
What is the use of InfluxDB?
InfluxDB is an open-source time series database (TSDB) developed by the company InfluxData. It is written in the Go programming language for storage and retrieval of time series data in fields such as operations monitoring, application metrics, Internet of Things sensor data, and real-time analytics.
What are retention policies?
A retention policy (also called a ‘schedule’) is a key part of the lifecycle of a record. It describes how long a business needs to keep a piece of information (record), where it’s stored and how to dispose of the record when its time.

How does a retention policy work?
When content has retention settings assigned to it, that content remains in its original location. Most of the time, people continue to work with their documents or mail as if nothing’s changed. But if they edit or delete content that’s included in the retention policy, a copy of the content is automatically retained.
