[jira] [Issue Comment Edited] (CASSANDRA-3693) strange values of
pending tasks with compactionstats (below 0)
[ https://issues.apache.org/jira/browse/CASSANDRA-3693?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13182293#comment-13182293 ]

--------------------------------------------------------------------
I'm using leveled compaction (with 4096mb limit, but with compression sstables are smaller).
There's a 80GB per node (3 nodes, replication factor=3).
# find /var/lib/cassandra/data -type f | wc -l
273
#
=> 273 sstables
compactionstats looks now like this:
pending tasks: -2147483648
compaction type keyspace column family bytes compacted bytes total progress
Compaction Archive Messages 35050352366 0 n/a
I wonder why 0 bytes total is visible on this node (nodetool ring is reporting 37.18GB).
After every compactions bytes total is about 73xxxxxxxxx (i guess it is not compress data size), but this value isn't saved anywhere.
