Original Downstream Change Summary This introduces a data format change to be able to compress arrays with the time-series column compression. Users downgrading to v5.0 will have a new floor on the v5.0 branch where the decompression support is included (tracked in Apart from the above, array compression works like object compression where scalar sub-fields are compressed. Description of Linked TicketAdd support for Arrays for the sub-object compression mode in BSONColumn. Arrays can mostly be treated as Objects but care need to be taken so we don't merge in when the types are different. Because there is existing data using this feature, we cannot use the existing control byte for sub-object mode start. An existing reference object with a sub-array need to not look for interleaved data for the array content. Arrays can also exist at the root level and we need a separate control byte for interleave start as an array. So: |
