Snapshotting Cluster Size Postgres

Snapshotting can take anywhere from a few minutes to several hours, depending on the size of your dataset, the upstream database, the number of tables (more tables can be parallelized in Postgres), and the size of your ingestion cluster.

We've observed the following approximate snapshot rates from PostgreSQL:

Cluster Size	Snapshot Rate
25 cc	~20 MB/s
100 cc	~50 MB/s
800 cc	~200 MB/s
