#3.0.7

Upgrading

• A maximum size for SSTables values has been introduced, to prevent out of memory
  exceptions when reading corrupt SSTables. This maximum size can be set via
  max_value_size_in_mb in cassandra.yaml. The default is 256MB, which matches the default
  value of native_transport_max_frame_size_in_mb. SSTables will be considered corrupt if
  they contain values whose size exceeds this limit. See CASSANDRA-9530 for more details.

Deprecation

• DateTieredCompactionStrategy has been deprecated - new tables should use
  TimeWindowCompactionStrategy. Note that migrating an existing DTCS-table to TWCS might
  cause increased compaction load for a while after the migration so make sure you run
  tests before migrating. Read CASSANDRA-9666 for background on this.

New features

• TimeWindowCompactionStrategy has been added. This has proven to be a better approach
  to time series compaction and new tables should use this instead of DTCS. See
  CASSANDRA-9666 for details.

Can make a stronger case for the "multi"-temperature storage.
