Dmitriy Pavlov updated IGNITE-8600:
-----------------------------------
Environment: (was: Currently our index cursor materializes rows as soon
as they are encountered in an index page. This is necessary to protect
ourselves from concurrent data modification. However, materialized rows might
be filtered out later due to additional filters. In addition, there is a chance
that only indexed fields is needed by query.
We can do the following:
1) Introduce new mode that will return partially materialized rows, with only
inline index fields initialized. When some non-initialized attribute is
requested, we go to data page and materialize the whole row
2) Enable this mode for MVCC by default
3) Optionally enable this mode for non-MVCC read-only mode through additional
flag.)
