To be queryable, your Delta Lake table must exist in AWS Glue. If your table is in Amazon S3
but not in AWS Glue, run a CREATE EXTERNAL TABLE statement using the following
syntax. If your table already exists in AWS Glue (for example, because you are using Apache
Spark or another engine with AWS Glue), you can skip this step.
CREATE EXTERNAL TABLE
[db_name.]table_name
LOCATION 's3://amzn-s3-demo-bucket/your-folder/'
TBLPROPERTIES ('table_type' = 'DELTA')Note the omission of column definitions, SerDe library, and other table properties. Unlike traditional Hive tables, Delta Lake table metadata are inferred from the Delta Lake transaction log and synchronized directly to AWS Glue.
Note
For Delta Lake tables, CREATE TABLE statements that include more
than the LOCATION and table_type property are not
allowed.
