Bootstrapping a node with vnodes with > this data layout will force cassandra to compact very many sstables in this > window. > We should probably put a cap on how big the biggest windows can get. We could > probably default this to something sane based on max_sstable_age (ie, say we > can reasonably handle 1000 sstables per node, then we can calculate how big > the windows should be to allow that) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
