There are a wide range of approaches and solutions to ensure that appropriate metadata is created and maintained. For example, you can add an e-mail address for the data owner (for example, one who is uploading the data) or add a tag to identify the data. While organizations sometimes simply accumulate content in a data lake without a metadata layer, this is a recipe for an unmanageable data swamp instead of a useful data lake. Making sure that all methods through which data arrives in the core data lake layer enforce the metadata creation requirement; and any new data ingestion routines must specify how the meta-data creation requirement will be enforced. In big data, even the metadata itself can be "big data". On the next page, click Launch Application. Managing data assets can be time consuming and expensive without the right tools. Hive Metastore, Apache Glue etc. The next page can be divided into the following segments.
