The automatic eviction of cached data beyond a certain period of time is a very useful feature for Presto users who have to comply with data privacy regulations like GDPR and CCPA. In this session, Chunxu and Jianjian will share the implementation of caching time-to-live (TTL) for data cached on the local disk. This feature not only helps Presto users with regulatory compliance but also can keep Presto’s local cache populated with the freshest, most relevant data.
You will learn:
– The implementation of TTL in Presto local cache
– Configurations and strategies for picking optimal TTL values
– Examples of using TTL to meet data privacy requirements while maximizing local cache performance gains
