Synchronized metadata

Updated: June 5, 2026

After you have registered and synchronized a data source, the following information is added to the Schema, Table, and Column assets.

Standard synchronized metadata

Synchronized metadata for Column assets

Column attribute	Description	From JDBC property (if provided by driver)
Column Name	The column name in the registered table.	COLUMN_NAME
Char octet Length	The maximum length of binary and character-based columns.	CHAR_OCTET_LENGTH
Column Position	The index of the column in the table.	ORDINAL_POSITION
Default Value	The default value of the column in the registered table.	COLUMN_DEF Note Currently, this isn't supported by any CDATA driver.
Description from Source	The description of the column in the registered table.	REMARKS
Is Auto Incremented	Indication whether the data in the column is auto-incremented or not.	IS_AUTOINCREMENT
Is Generated	Indication whether the data in the column is generated or not.	IS_GENERATEDCOLUMN
Is Nullable	Indication whether the column can store NULL values or not. The default value is: True.	IS_NULLABLE
Is Primary Key	Indication whether the column is a primary key or not. The default value is: False.	True if the primary keys resultSet contains the COLUMN_NAME
Number Of Fractional Digits	The number of decimal digits.	DECIMAL_DIGITS
Primary Key Name	The name of the primary key composed by the column.	PK_NAME
Size	The length in characters of the column or the numeric precision.	COLUMN_SIZE
Technical Data Type	The data type of the column in the data source. This value can differ from the Data Type value. Tip You see the technical data type in the Technical Data Type field in the At a glance sidebar of the Column asset. If the At a glance sidebar is hidden, click . For Amazon Athena and AWS Glue connections you can also see the structured technical data type, Array or Struct, if you have set the Other property to `SupportNativeDataType=true`. When you view the metadata synchronization results, click the hyperlink to see the structure of the data in a dialog box. In other locations, for example in Table assets, click the View Array or View Struct button to open the dialog box. Show an example	TYPE_NAME

Synchronized metadata for Table assets

Table attribute	Description	From JDBC property (if provided by driver)
Table Name	The table name in the data source.	TABLE_NAME
Description from Source	The description of the table in the data source.	REMARKS
URL	Uniform Resource Locator, also colloquially known as web address. Note This attribute is registered only for AWS Glue data sources.	S3Path
Table Type	The table type in the data source, such as TABLE or VIEW.	TABLE_TYPE

Synchronized metadata for Schema assets

Schema attribute	Description	From JDBC (if provided by driver)
Data source type	The type of the registered data source.	DatabaseMetaData.getDatabaseProductName()
Source tags	The tags assigned to the asset in the source system. Note Currently, the JDBC registration process can synchronize source tags only from Snowflake via this method. For information on synchronizing the source tags from Databricks Unity Catalog, go to Add the Databricks Unity Catalog capability.	<database_name>.INFORMATION_SCHEMA.tag_ or SNOWFLAKE.ACCOUNT_USAGE.tags

Schema attribute

Description

From JDBC (if provided by driver)

Data source type

The type of the registered data source.

DatabaseMetaData.getDatabaseProductName()

Source tags

The tags assigned to the asset in the source system.

Note Currently, the JDBC registration process can synchronize source tags only from Snowflake via this method.
For information on synchronizing the source tags from Databricks Unity Catalog, go to Add the Databricks Unity Catalog capability.

<database_name>.INFORMATION_SCHEMA.tag_
or
SNOWFLAKE.ACCOUNT_USAGE.tags

Conditionally synchronized metadata

If you synchronize the data usage statistics, the data usage information and a calculated popularity score become available for Table, View, and Column assets.
Important
- Currently, the JDBC registration process can synchronize the data usage statistics and calculate a popularity score only for Snowflake.
- This feature is available only in the latest UI for Commercial Cloud customers and when the scalable ingestion flow is enabled.
- The popularity score of an asset is recalculated twice a day and takes the data usage statistics of the last 30 days of the last gathered information into account.
If you synchronize the source tags, the tags defined on the assets in the data source are registered and available from the Schema, Table, Database View, and Column assets in the Source Tags attribute.
Note Currently, the JDBC registration process can synchronize source tags only from Snowflake via this method.
For information on synchronizing the source tags from Databricks Unity Catalog, go to Add the Databricks Unity Catalog capability.

For all Snowflake-specific synchronized metadata, go to Synchronized Snowflake data and characteristics mapping.
