====== Data Resource - Size ======


===== About =====
''size'' is a [[attribute|data resource attribute]] that shows the size of a [[resource|data resource]] in ''byte'' on disk.

The value is ''-1'' if the size is not yet implemented by the system.


===== Example =====

With the [[docs:connection:howto|howto file]] ''characters.csv'' and the [[docs:tabul:data:list|data list command]]
<unit>
<code bash>
tabul data list --attribute size characters.csv@howto
</code>
<console>
path             media_type   size
--------------   ----------   ----
characters.csv   text/csv      432
</console>
</unit>



===== Size type by system =====

  * for a [[file|file]], the ''size'' reported is the [[https://docs.oracle.com/javase/8/docs/api/java/nio/file/attribute/BasicFileAttributes.html#size--|Size file attribute]] reported by the [[:docs:system:file|file system]]
  * for a [[:docs:resource:sql_table|table]], it's its data and index size. You should consult the below Tabulify database documentation to see where the value exactly comes from.
    * [[docs:system:postgres:table_size|]]
    * [[:docs:system:sqlserver:table_size|]]
