Exporting Data

Scenarios

User data on GeminiDB Influx instances can be converted into a Parquet file and automatically uploaded to a specified OBS bucket. You can use big data products to directly access the Parquet file or download it to your local PC.

Precautions

• To export data, choose Service Tickets > Create Service Ticket in the upper right corner of the console.

• Data can be exported only from GeminiDB Influx instances whose DB Instance Type is set to Cluster (performance-enhanced).
• To use this function, you need to enable Export Data.
• OBS supports parallel file systems and standard buckets.
• Data can be exported to a specified folder, which cannot be empty.
• When you export data, a policy named data-dump-access is created on OBS. This policy provides only the PUT permission and applies only to the selected folder.

• After Export Data is enabled, Parquet files are automatically uploaded to the selected OBS directory every 2 hours.
