add_minmax_index_for_block_number_column
When enabled, an implicit min-max (skipping) index is added for the persistent virtual column_block_number.
Requires enable_block_number_column = 1 to take effect. The index is built only during merges,
not during inserts: at insert time the block number is provisional and would index a constant.
add_minmax_index_for_block_offset_column
When enabled, an implicit min-max (skipping) index is added for the persistent virtual column_block_offset.
Requires enable_block_offset_column = 1 to take effect. The index is built only during merges,
not during inserts.
