Mobile geodatabase size and name limits

Mobile geodatabase size and name limits are as follows:

  • Mobile geodatabase size—2 TB database limit

  • Table or feature class size—No limit within the 2 TB database limit

    Tip:

    SQLite is a self-contained database file format that stores the entire database in a single file on disk. All SQLite database objects in a mobile geodatabase, such as the geodatabase tables, indexes, triggers, and views, use some of the available space within this 2 TB limit.

  • Number of feature classes and tables—2,147,483,647

  • Number of fields in a feature class or table—2,000

  • Number of rows in a feature class or table—2,147,483,647

  • Geodatabase name length—The number of characters the operating system allows in a folder name

    Note:

    • Since a mobile geodatabase (.geodatabase file) is built on top of SQLite, the name of the mobile geodatabase consists of the file path, file name, and file extension.

      For example, if you are using a Windows operating system, the name of this mobile geodatabase, C:\GIS_Data\Projects\Mobile_Geodatabase\Project1_data.geodatabase, contains 65 characters.

    • The database names main and temp are reserved SQLite database names.

  • Feature dataset name length—160 characters

  • Feature class or table name length—128 characters

  • Index name length—128 characters

  • Field name length—128 characters

  • Text field width—1,000,000,000 bytes

  • Domain name length—257 characters

  • Attribute Rule

    • Name—64 characters

    • Description—256 characters
