Because the COUNTRY_ID is not part of the CITIES primary key, and maybe because my data model may have to cope with cities changing to another country (geopolitical immutability). It is definitely not a good choice here for areas, latitude and longitude. Note that I did that for the demo because CURRENCY_ID was first in the primary key declaration, but you may think more about data distribution and lifecycle when deciding on interleaving. What I like with this data set is that, in addition to providing the CSV, Gerald have managed to provide a unique DDL + DML to create this data in SQL databases. I have posted, a long time ago, about Google Spanner (inserting data and no decimal numeric data types) but many things have changed in this area. Instead, it ingests pg_dump output, automatically builds a Spanner schema, and creates a new Spanner database populated with data from pg_dump. The following tables track the queries with the highest CPU usage during a specific time period: . If you come from Oracle, you may see this INTERLEAVE IN PARENT as a table CLUSTER but on a partitioned table. Then you pick the cloud project and, optionally, a default region and zone.
