Started exports and imports of a couple of large tables. Will post my timings after it is done.
But did anybody have any timings for gcloud sql export --offload for large tables?
Interested for single large tables of like 1TiB and 16TiB?
~1 TiB export took ~27 hours end-to-end via serverless offload export single-threaded (parallel flag not used) from a CloudSQL MySQL instance into a GCS bucket as compressed sql.gz file.
The import of that export took 9h50m into a CloudSQL MySQL instance with tier db-custom-8-32768 with PD_SSD disk type.
Note, this is not a benchmark - as these things likely depend on lots of factors outside of my control, and this was performed over the weekend.
