---------------------------------------
Component/s: sql
> Incorrect vartable compaction to TINY format.
> ---------------------------------------------
>
> Key: IGNITE-15744
> URL: https://issues.apache.org/jira/browse/IGNITE-15744
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Affects Versions: 3.0.0-alpha2
> Reporter: Andrey Mashenkov
> Priority: Major
> Labels: iep-54, ignite-3
> Fix For: 3.0.0-alpha4
>
>
> Var-table compaction may lead to row data corruption when {{TINY}} format is
> selected
> in case of 256+ empty (not null) varlen fields.
> {{TINY}} format will be selected in this case, because payload size fit to a
> single byte,
> however, the size of vartable will be truncated{{ int->byte}} with overflow.
> Possible fixes are:
> * switch to {{MEDIUM}} format
> * always use {{short}} for vartable size
