-rw-rw---- 1 mysql mysql 3724541952 Feb 11 03:51 profile_locations#P#p0.ibd
-rw-rw---- 1 mysql mysql 4445962240 Feb 11 03:52 profile_locations#P#p1.ibd
-rw-rw---- 1 mysql mysql 3766484992 Feb 11 01:23 profile_locations#P#p2.ibd
-rw-rw---- 1 mysql mysql 4240441344 Feb 11 02:35 profile_locations#P#p3.ibd
-rw-rw---- 1 mysql mysql 4219469824 Feb 11 02:01 profile_locations#P#p4.ibd
-rw-rw---- 1 mysql mysql 4190109696 Feb 9 16:55 profile_locations#P#p5.ibd
-rw-rw---- 1 mysql mysql 5196742656 Feb 11 03:33 profile_locations#P#p6.ibd
-rw-rw---- 1 mysql mysql 5007998976 Feb 11 03:54 profile_locations#P#p7.ibd
-rw-rw---- 1 mysql mysql 5200936960 Feb 11 03:53 profile_locations#P#p8.ibd
-rw-rw---- 1 mysql mysql 5175771136 Feb 11 04:21 profile_locations#P#p9.ibd


TOTAL: 45168459776 bytes = 42.0664062 gigabytes


After Running this:
ALTER TABLE profile_locations REMOVE PARTITIONING;

We get:
-rw-rw---- 1 mysql mysql 51065651200 Feb 11 16:29 profile_locations.ibd

thats 51065651200bytes = 47.5585938 gigabytes

HUH ?

According to mysql "guru s" partitioning should take MORE space... how in the world this case scenario makes any sense ?
