If I drop an innodb table when will the disk space be reclaimed?
Does it happen immediately?

How about with records instead of the entire table?

    It depends on whether you enabled the innodb_file_per_table server setting or not.

    If innodb_file_per_table is enabled, then each table stores its data in a separate .ibd file. Otherwise the data for all tables is stored in a shared .ibd file.

    With innodb_file_per_table:

    • When you drop a table the .ibd file is deleted and the disk space is immediately freed.
    • When you delete records it frees up space inside the .ibd file, but does not shrink it. Rebuilding the table (such as by running OPTIMIZE TABLE) will free up the disk space.

    Without innodb_file_per_table:

    • Dropping a table or deleting rows from a table frees up space in the shared .ibd file to be used to store future data, but the shared .ibd file will never shrink
