Bulk write without shard key using the single shard optimization may target documents incorrectly
Last update date:
3/18/2024
Affected products:
MongoDB Server
Affected releases:
No affected releases provided.
Fixed releases:
8.0 Required
Description:
Info
Similar to the issue in SERVER-87191, it looks like bulk writes without shard key uses getNShardsOwningChunks, which does not respect the atClusterTime in the case of a transaction with snapshot read concern. This can lead to inconsistent targeting as described in the previous ticket.
