------------------------------------
Summary: Cold Storage Directory Support for DTCS
Key: CASSANDRA-9394
URL: https://issues.apache.org/jira/browse/CASSANDRA-9394
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Jim Plush
Priority: Minor
Date Tiered Compaction for time series data at high volume it seems like a good
candidate for multi-tiered storage options for cost reduction purposes.
For example setting max_sstable_age_days = 1 means that once a file hits 1 day
old it won't be a candidate for compaction any longer. For immutable time
series data you could in theory then have a new DTCS and yaml setting that says
move anything over X days (table def) into the cold storage directory from the
yaml file.
This way you could have pricer, smaller SSD drives for recent data and cheaper,
magnetic storage for longer term data that is infrequently read after a certain
period of time.
cc [~Bj0rn] for input and feasibility.
