Oplog generated from versions
What changes in Oplog generated from versions compared with MongoDB and what your application has to do.
This difference is of the Different kind.
What MongoDB does
The oplog records each change with data from its files, such as the document count when a collection is dropped.
What TeselaDB does
local.oplog.rs comes from the document versions. The drop entry carries no document count. The identifiers of create and createIndexes do not name files.
What your application has to do
If a tool reads those oplog fields, make it treat them as optional.
