# Bug 11766634 59783: InnoDB data grows unexpectedly when inserting,
|
|
# truncating, inserting the same set of rows.
|
|
#
|
|
# Scenario:
|
|
# create table t1. Insert $recs records. check size of ibdata1.
|
|
# drop table t1. create table t1. Insert the same set of $recs
|
|
# records. The size of ibdata1 must not increase.
