CREATE-DATABASE

Name

CREATE DATABASE

Description

This statement is used to create a new database (database)

grammar:

CREATE DATABASE [IF NOT EXISTS] db_name
    [PROPERTIES ("key"="value", ...)];

PROPERTIES Additional information about the database, which can be defaulted.

• If you want to specify the default replica distribution for tables in db, you need to specify replication_allocation (the replication_allocation attribute of table will have higher priority than db)

  PROPERTIES (
    "replication_allocation" = "tag.location.default:3"
  )

Example

1. Create a new database db_test

   CREATE DATABASE db_test;

2. Create a new database with default replica distribution:

   CREATE DATABASE `iceberg_test`
   PROPERTIES (
       "replication_allocation" = "tag.location.group_1:3"
   );
