------------------------------------
Summary: Index summary downsampling prevents mmap access of large
files after restart
Key: CASSANDRA-10511
URL: https://issues.apache.org/jira/browse/CASSANDRA-10511
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Benedict
Fix For: 3.x, 2.1.x, 2.2.x, 3.0.x
{{SSTableReader.cloneWithNewSummarySampleLevel}} constructs a
{{SegmentedFile.Builder}} but never populates it with any boundaries. For files
larger than 2Gb, this will result in their being accessed via buffered io after
a restart.
