Wes McKinney commented on ARROW-41:
-----------------------------------
Note that {{arrow::Table}} (as compared with {{arrow::RowBatch}}), as currently
defined, is a chunked data structure:

> This may require memory allocation depending on the chunking of the table
> columns.
> While tables and struct type columns are semantically equivalent (and tables
> can be embedded in other tables using struct types), the memory layout of a
> table may not be strictly contiguous. For the purposes of putting data on the
> wire / in shared memory, it may be useful to offer a conversion function to
> "structify" an in-memory logical Arrow table. See ARROW-24
