Shail Walia, a senior technical architect at Snowflake, joins host Robert Blumen for a dialog about schema migration and knowledge migration. Collectively, they talk about the fundamentals of schema: do all knowledge units have schema?; what drives schema change?; are knowledge migration and schema migration the identical factor? Should they occur on the identical time? They then discuss concerning the challenges and failure modes of schema migration, together with challenges at scale, migrating with out downtime, the idea of “security” in knowledge migrations, and security patterns for knowledge migration – double writes, learn restore, replication, ending on the Apache Iceberg case research.
