Staging files


Data streams are written to a temporary Iceberg table, and then loaded into Amazon S3 Starburst Galaxy catalog in the Iceberg table format. Staging table is deleted after a sync is complete if the Purge staging Iceberg table is enabled. The following is an example of a full path for a staging file:

s3://<bucket-name>/<bucket-path>/<namespace/schema>/<temp Iceberg table name {_airbyte_tmp_random-three-chars_stream-name}>

For example:

↑ ↑ ↑ ↑
| | | temporary Iceberg table holding data
| | source namespace or provided schema name
| |
| bucket path
bucket name

Target Iceberg SQL table

Streams are synced in the Starburst Galaxy Amazon S3 catalog with Iceberg table format.

Output schema

Each table in the output schema has the following columns:

_airbyte_emitted_attimestamp(6)Data emission timestamp.
Data fields from the source streamvariousAll the fields from the source stream will be populated as an individual column in the target table.
_airbyte_additional_propertiesmap(varchar, varchar)Additional properties.

The Airbyte data stream's JSON schema is converted to an Avro schema. The JSON object is then converted to an Avro record; the Avro record is written to a staging Iceberg table. As the data stream can be generated from any data source, the JSON-to-Avro conversion process has arbitrary rules and limitations. Learn more about how source data is converted to Avro.
