Module export_v2 

Export V2 module.

This module provides the V2 implementation of database export functionality, featuring:

• JSON-based schema export (version-agnostic)
• Manifest-based snapshot management
• Support for multiple storage backends (S3, OSS, GCS, Azure Blob, local FS)
• Resume capability for interrupted exports

Example

# Export schema only
greptime cli data export-v2 create \
  --addr 127.0.0.1:4000 \
  --to file:///tmp/snapshot \
  --schema-only

# Export with time range
greptime cli data export-v2 create \
  --addr 127.0.0.1:4000 \
  --to s3://bucket/snapshots/prod-20250101 \
  --start-time 2025-01-01T00:00:00Z \
  --end-time 2025-01-31T23:59:59Z
