io.delta.kernel.internal.actions.CommitInfo

public class CommitInfo
extends Object

Delta log action representing a commit information action. According to the Delta protocol there isn't any specific schema for this action, but we use the following schema:

• timestamp: Long - Milliseconds since epoch UTC of when this commit happened
• engineInfo: String - Engine that made this commit
• operation: String - Operation (e.g. insert, delete, merge etc.)
• operationParameters: Map(String, String) - each operation depending upon the type may add zero or more parameters about the operation. E.g. when creating a table `partitionBy` key with list of partition columns is added.
• isBlindAppend: Boolean - Is this commit a blind append?
• txnId: String - a unique transaction id of this commit

The Delta-Spark connector adds lot more fields to this action. We can add them as needed.
