| Description |
|
In SERVER-69396 we will explore replacing the full-document updates of time-series insertions with WT_MODIFY application as it reduces the I/O used significantly. As normal Oplog updates already contain a Diff object sometimes, we could directly apply the computed damages instead of materializing the full document update. Note that this directly depends on WT-9668 and should only be started after the ticket gets resolved. |
