What can be specified when creating a table in Hive?
In Hive, you can specify the following details to create a table:
- Table name: the designated name of the table.
- Column: Defines the column name and data type of the table.
- Partitioning involves dividing data into different directories or subdirectories based on a column in the table. You can specify the column name and data type for partitioning.
- Storage format: specify the format in which the table will be stored, such as text files, Parquet, ORC, etc.
- Delimiter: If storing data in a text file, you can specify the delimiter between columns.
- Table attributes: can specify certain attributes of a table, such as comments and types.
- External table: a table can be designated as an external table, where the data is stored in an external file system and not managed by Hive.
- Table location: the storage location of the table can be specified, by default, Hive stores tables in the /user/hive/warehouse directory in the Hadoop file system.
The above options can be used to create a Hive table as needed.
