I need to update some documents at once, like a RDBMS transaction. The best way to do this for a single document in a key-value store like couchbase seems to be using optimistic locking. This would work for me. However, I need to update multiple documents at once.
I need all documents to be updated, or none. Is this possible in couchbase or some similar highly scalable database?
(by the way, I'm using Go)
分享 There are three approaches to resolve it:
You should take another look at your key/document designs and identify if its possible to combine your multiple docs into one. Then you will be able to do a single transactional update in Couchbase.
Simulate Transaction the effect can be simulated by writing a suitable document and view definition that produces the effect while still only requiring a single document update to be applied.
Simulate Multi-phase Transactions to use the transaction record to record each stage of the update process
