Bringing your own data
----------------------

It’s possible to point your Lakehouse node at an arbitrary S3 bucket
with Delta Tables inside of it. However, there are some major caveats to
doing so. (These will be resolved in future releases.)

Caveats
^^^^^^^

- The tables must be stored as `Delta Lake Tables <http://github.com/delta-io/delta/blob/master/PROTOCOL.md>`_  within the location.

- A *Delta Lake Table* (or *Delta Table*) is a folder of Parquet files
  along with some JSON metadata.

Loading data into your bucket
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You can use the lakehouse-loader utility to export data from an
arbitrary Postgres instance to Delta Tables in a storage bucket. See
:ref:`Delta Lake Table tools <Delta Lake Table tools>`  for more information on how to get and use that utility.

For more details, see `querying delta tables <https://enterprisedb.com/docs/edb-postgres-ai/hybrid-manager/analytics/learn/how-to/query-delta-lake-tables>`_  .
