Exists in documentation for 5.7 too, most likely introduced in that version as the example is not present for 5.6 and 5.5

Hello Sumeeti, Thank you for the report. I checked internally with the Innodb Dev and confirmed that this is by design and expected behavior(due to b-tree restrictions) which is even explicitly commented in code. /* The maximum allowed record size is half a B-tree page(16k for 64k page size). No additional sparse page directory entry will be generated for the first few user records. */ Marking this as !bg. regards, Umesh
