> Skip writing null-map and varlen table when possible
> ----------------------------------------------------

> Key: IGNITE-13670
> URL: https://issues.apache.org/jira/browse/IGNITE-13670
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexey Goncharuk
> Priority: Major
> Labels: iep-54, ignite-3
>
> The nullmap is currently always written to the tuple layout for all columns
> (even if there are no nullable columns). This data structure can be further
> used to encode default values for non-nullable columns (either a
> user-specified value or 0 for primitives).
> The bits will still be left unused for non-null non-primitive types (UUID,
> String, byte[], etc).
> Also, need to add support for skipping writing nullmaps (use the flags bit).
