The introduction of DateTieredCompactionStrategy in late 2014 was a significant step forward in providing a viable compaction strategy for time series data, especially time series data that will be TTL'd out. DateTieredCompactionStrategy's introduction was met with genuine excitement, and its rapid adoption is testament to developers' and operators' desire to have data compacted in a way that better matches their write patterns.
However, DateTieredCompactionStrategy's features come with significant limitations. This talk will review our real world benchmarking and use cases for DTCS as a vehicle to discuss the implications of DateTieredCompactionStrategy on operational tasks such as repair, read-repair, bootstrapping, and especially DR recovery scenarios, and it will also discuss how those various limitations lead us to proposing an operations-friendly alternative to DateTieredCompactionStrategy.
