------------------------------------------
Summary: Utility sstableexpiredblockers should report the size of
expired tables
Key: CASSANDRA-20448
URL: https://issues.apache.org/jira/browse/CASSANDRA-20448
Project: Apache Cassandra
Issue Type: Improvement
Reporter: Brad Schoening
A key reason to run sstableexpiredblockers is that you have disk space
accumulating and you wish to investigate what's consuming the disk space.
If size was included in the output (as shown below), it would make the output
more useful. Generally, when you find a blocked expired table, the first step
is to check what size it is to see if it's large enough to be a problem.

(minTS = 5, maxTS = 5, maxLDT = 2147483647)], blocks 1 expired sstables from
getting dropped:
[BigTableReader(path='/var/lib/cassandra/data/keyspace1/standard1-0665ae80b2d711e886c66d2c86545d91/mc-3-big-Data.db')
({*}diskSize = 135.7 GB{*}, minTS = 1536349775157606, maxTS =
1536349780311159, maxLDT = 1536349780)],{quote}
Also, it would be preferable to report min/max timestamp in date-time format
e.g.:
{quote} diskSize =134.3 GB, minTimestamp = 2025-03-10T00:00:00.000+00:00
{quote}
