Indexing Pressure should also account for the parsing memory #121651
Description
Description
Indexing pressure does not currently account for the extra heap memory required for parsing indexed documents, i.e. by the index.mapper.SourceToParse and jackson.core.util.ReadConstrainedTextBuffer classes. In the worst cases, the extra memory can be 1x and 2x, respectively, the memory of the indexed document (the memory that's accounted by the IndexingPressure).
In some cases this can OOM the node rather than reject the indexing request.
