> PostgreSQL databases typically don't generate huge amounts of data The live data set may not be huge, but the entire trail of all changes of all current and all previously existing data may easily exceed the volume of data you can reasonably process with Postgres. In addition, its row based storage format doesn't make it an ideal fit for typical analytical queries on large amounts of data. Replicating the data from Postgres to Iceberg addresses these issues. But, of course, it's not without its own challenges, as demonstrated by the article.
