Hi! Does https://github.com/delta-io/delta-rs (Python version) guarantee the delta-concurrency ?

as far as I understand, the concurrency control is achieved by the log store, which depends on the what the storage service is used. For example, Azure Blob, GCS has built-in support that only one writer can succeed. But for s3, in the case of the multi-cluster(drivers), it is a bit complex to achieve, you have to use the DynamoDB together within your configuration.

Is HDFS can achieve the concurrency control

i do not think so

Thank you, Yi, this was very helpful.
