A table’s partition configuration can evolve if, for example, its data volume changes. Queries do not need to change because partition filters are derived from data predicates. In v1-v3, each manifest uses a single partition spec. Review Comment: ```suggestion * Tables can use multiple partition specs. A table’s partition configuration can evolve if, for example, its data volume changes. Partition predicates for a partition spec are derived from data predicates and can be applied to filter files written using that spec. Prior to v4, a manifest stored files partitioned by single spec. ``` -- This is an automated message from the Apache Git Service.
