deletedAt and localDeletion

Hi all,

Can anyone explain what mine deletedAt and localDeletion in
SliceQueryFilter log.

SliceQueryFilter.java (line 225) Read 6 live and 2688 tombstoned cells in
ks.mytable (see tombstone_warn_threshold). 10 columns was requested,
slices=[-], delInfo={deletedAt=-9223372036854775808,
localDeletion=2147483647}

Thanks,

If you look at the source there are some useful comments regarding those
specifics
https://github.com/apache/cassandra/blob/8d8fed52242c34b477d0384ba1d1ce3978efbbe8/src/java/org/apache/cassandra/db/DeletionTime.java

/** * A timestamp (typically in microseconds since the unix epoch, although
this is not enforced) after which * data should be considered deleted. If
set to Long.MIN_VALUE, this implies that the data has not been marked * for
deletion at all. */ public final long markedForDeleteAt; /** * The local
server timestamp, in seconds since the unix epoch, at which this tombstone
was created. This is * only used for purposes of purging the tombstone
after gc_grace_seconds have elapsed. */ public final int localDeletionTime;
