> Now if you run sstabledump (even after taking the [patch|https://github.com/yukim/cassandra/tree/11654-3.0]
for CASSANDRA-11654) against the newly generated SSTable like the following:
> {noformat}
> ~/cassandra-trunk/tools/bin/sstabledump ma-1-big-Data.db
> [
>   {
>     "partition" : {
>       "key" : [ "1" ],
>       "position" : 0
>     },
>     "rows" : [
>       {
>         "type" : "row",
>         "position" : 18,
>         "clustering" : [ "c1" ],
>         "liveness_info" : { "tstamp" : 1461645231352208 },
>         "cells" : [
>           { "name" : "val0_int", "value" : "100" }
>         ]
>       }
>     ]
>   }
> ]
> {noformat}
> You will see that the collection-level Deletion Info is nowhere to be found, so you will
not be able to know "markedForDeleteAt" or "localDeletionTime" for this collection tombstone.
