Hi.I try to find the original source about `reconciliation` in database fields, but no result (Obviously  is not what WT means). So,1. Who was the first one that coined the term ?
2. Compared to Innodb, why does WT need reconciliation ? (I guess Innodb page is fixed and just synced to disk pages, whereas WT's page is not)
I think it maybe gets better concurrency to make in-memory representation differ from on-disk representation. In a memory page, it has linkedlists and skiplists. Writer will not block reader for the same key.
