> We create a secondary index for a specific column.
> After running a few months, by using sstable2json tool, we found there are some unknown
keys which we've never assigned are stored in the sstable of the secondary index. The key
value is incremental hexbyte, for example, 55012157, 55012158.
> It can not be removed by nodetool repair/compact/cleanup.
> When the sstable of the secondary index become larger, the read performance is dropped.
