This states that the work should be run in a thread with minimal isolation. +
For instance, it will share the same classloader that the task is loaded from.
This is the fastest level of isolation.

the source object version, such as metadata updates via PutObjectTagging, PutObjectRetention, PutObjectLegalHold and COPY api are replicated in a similar manner to target version, with the `X-Amz-Replication-Status` again cycling through the same states.

The description above details one way replication from source to target w.r.t incoming object uploads and metadata changes to source object version. If active-active replication is configured, any incoming uploads and metadata changes to...
