Part 10/16:
Multiple table engines (MergeTree family, ReplacingMergeTree, AggregatingMergeTree) facilitate tailored storage for different data scenarios, such as deduplication or pre-aggregation.
Replication and data merging optimize for both high availability and query speed.
This architecture offers up to 10x data compression and efficient merging abilities, ensuring that even petabyte-scale datasets are manageable and performant.
