mxm opened a new pull request, #13032: URL: https://github.com/apache/iceberg/pull/13032
This adds the classes around schema / spec comparison and evolution. Broken out of https://github.com/apache/iceberg/pull/12424, depends on https://github.com/apache/iceberg/pull/12996 (first commit). The second commit contains required Iceberg cores changes for partition spec evolution and schema evolution testing. A breakdown of the classes follows: # CompareSchemasVisitor Compares the user-provided schema against the current table schema. # EvolveSchemaVisitor Computes the changes required to the table schema to be compatible with the user-provided schema. # ParititonSpecEvolution Code for checking compatibility with the user-provided partition spec and computing a set of changes to rewrite the PartitionSpec. # TableDataCache Cache which holds all relevant metadata of a table like its name, branch, schema, partition spec. Also holds a cache of past comparison results for a given table's schema and a user-provided input schema. # Table Updater Core logic to compare and create/update a table given a user-provided input schema. -- This is an automated message from the Apache Git Service.
