Migrating data from self-managed InfluxDB to Timestream for InfluxDB
The Influx migration script
InfluxDB is a time series database. InfluxDB contains points, which contain a number of key-value pairs and a timestamp. When points are grouped by key-value pairs, they form a series. A series is grouped by a string identifier called a measurement. InfluxDB is often used for operations monitoring, IOT data, and analytics. A bucket is a kind of container within InfluxDB to store data. AWS-managed InfluxDB is InfluxDB within the AWS ecosystem. InfluxDB provides the InfluxDB v2 API for accessing data and making changes to the database. The InfluxDB v2 API is what the Influx migration script uses to migrate data.
The Influx migration script can migrate buckets and their metadata, migrate all buckets from all organizations, or do a full migration, which replaces all data on the destination instance.
The script backups data from the source instance locally, on whatever system executes the script, then restores the data to the destination instance. The data is kept in code>influxdb-backup-<timestamp></timestamp> directories, one for each migration.
The script provides a number of options and configurations including mounting S3 buckets to limit local storage usage during migration and choosing which organizations to use during migration.
