Similar to the system tablespace, truncating or dropping tables stored in a general tablespace creates free space internally in the general tablespace .ibd data file which can only be used for new
InnoDBdata. Space is not released back to the operating system as it is for file-per-table tablespaces.
This example demonstrates how to drop an
general tablespace. The general tablespace
is created with a single table. Before dropping the tablespace,
the table must be dropped.
