Get started with Delta Lake tables

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. 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.

CREATE EXTERNAL TABLE
  [db_name.]table_name
  LOCATION 's3://amzn-s3-demo-bucket/your-folder/'
  TBLPROPERTIES ('table_type' = 'DELTA')
Note

  • This statement is not compatible with S3 buckets that have requester pays enabled. If you want to create a Delta Lake table against an S3 bucket with requester pays enabled, follow the instructions and DDL statement in .

  • For Delta Lake tables, CREATE TABLE statements that include more than the LOCATION and table_type property are not allowed.
