Maximum number of items in a transaction using Azure.Data.Tables

Question

One of the migration tasks is to convert batch operations. What is the limit of items in one transaction is when calling the SubmitTransactionAsync method, as shown on the example below? The documentation does not say the maximum number.

var transactionActions = new List<TableTransactionAction>();

foreach (var row in items)
{
    transactionActions.Add(new TableTransactionAction(TableTransactionActionType.Delete, row));
}

table.SubmitTransactionAsync(transactionActions).Wait();
