availability, recovery semantics, and guarantees Vasiliki Kalavri | Boston University 2020 Today’s topics • High-availability and fault-tolerance in distributed stream processing • Recovery semantics and guarantees against failures and guarantee correct results after recovery? • how can we ensure minimal downtime and fast recovery? • how can we hide recovery side-effects from downstream applications? Vasiliki failures. 7 Vasiliki Kalavri | Boston University 2020 Recovery types 8 Vasiliki Kalavri | Boston University 2020 Recovery types • Precise recovery (exactly-once) • It hides the effects of a failure

K1: Data Stream Processing and Analytics Spring 2020 2/04: Streaming languages and operator semantics Vasiliki Kalavri | Boston University 2020 Vasiliki Kalavri | Boston University 2020 Languages Almost universally supported across streaming systems and languages albeit with various names and semantics • Allow un-blocking the processing of blocking operators by defining bounded portions of the Continuous queries on data streams • New streams (derived) are defined as virtual views in SQL • Semantics are equivalent to having an append-only table to which new tuples are continuously added. 34
