------------------------------------
Fix Version/s: 2.4
> SQL: bypass H2 during index update
> ----------------------------------
>
> Key: IGNITE-6409
> URL: https://issues.apache.org/jira/browse/IGNITE-6409
> Project: Ignite
> Issue Type: Task
> Components: persistence, sql
> Affects Versions: 2.1
> Reporter: Vladimir Ozerov
> Labels: iep-1, performance
> Fix For: 2.4
>
>
> Currently the only way to update standard user index is through H2
> infrastructure. See {{GridH2IndexBase#put}} and it's usages. For every update
> we have to construct a kind of H2 rowm which will be passed to index. This
> operation might require unnecesary memory copying and deserializations.
> We should try to find a way to bypass H2 stuff altogether and add data to
> underlying {{BPlusTree}} directly.
