This is a follow-up change for #8454.
Usually a Gluten query plan knows exactly the batch type of data it processes with the help from Gluten's transition planner. Table cache write is an exception here because vanilla Spark's cache generation code simply calls API
CachedBatchSerializer#convertColumnarBatchToCachedBatchfor a child plan withsupportsColumnar=true. Hence, we have to dynamically do to-Velox batch conversions in the implementation code ofCachedBatchSerializer#convertColumnarBatchToCachedBatchbecause we don't know the batch type the child plan outputs.The patch adds an
ensureVeloxBatchAPI for dynamical to-Velox batch conversion. The API should only be used in table cache write or similar scenarios that explicit transitions are not able to add.The patch adds a test case for the original issue #8453 also.
