> In addition, I've changed Iterators.partition(Tables.rows(tbl),chunksize) to Iterators.partition(tbl,chunksize) to avoid missingness type getting lost (eg, for DataFrames) Okay, I was wrong. I misunderstood what `rowaccess` requirements are -- `Iterators.partition()` still needs to be defined separately. I've moved back to Tables.rows to ensure we get rows out. I'm not sure what the best solution is here. By far the simplest option would be to pass the schema down - because we have access to it before `Tables.columns` is called in the arrow construction (that's how we lose the schema, because we "materialize" the chunk as is) -- This is an automated message from the Apache Git Service.
