Version of the table that was read to perform the write operation. ![]() ID of the cluster on which the operation ran. Parameters of the operation (for example, predicates.)ĭetails of the job that ran the operation.ĭetails of notebook from which the operation was run. Table version generated by the operation. The output of the history operation has the following columns. In addition to the table schema and sample data, you can click the History tab to see the table history that displays with DESCRIBE HISTORY. See the Delta Lake API documentation for Scala/Java/Python syntax details.ĭata Explorer provides a visual view of this detailed table information and history for Delta tables. DESCRIBE HISTORY '/data/events/' - get the full history of the tableĭESCRIBE HISTORY '/data/events/' LIMIT 1 - get the last operation onlyįor Spark SQL syntax details, see DESCRIBE HISTORY. By default table history is retained for 30 days. The operations are returned in reverse chronological order. You can retrieve information on the operations, user, timestamp, and so on for each write to a Delta tableīy running the history command. You can use history information to audit operations or query a table at a specific point in time. Use along with dictionary values finds the largest value in the dictionary.Each operation that modifies a Delta Lake table creates a new table version.If you use the keys function along with this, then it finds the maximum key within a Dictionary.The Python max function helps you find the maximum value in the Dictionary. Print("Largest String in a List = ", max(StrLiA)) max Dictionary ![]() Print("Largest Value in this List = ", max(LiA)) Next, we find the largest item in a string list. Here, we declared a numeric list and found the maximum value in that list using it. It also helps you to find the maximum list item available in a given List. StrTp = ('berry', 'orange', 'banana', 'mango') NOTE: Finding the largest string tuple means it returns the word that starts with the highest Alphabet. Next, we find the largest value inside a string tuple. First, we declared an integer tuple and found the highest value inside an integer tuple. This example finds the maximum item in a Tuple or finds the largest value in this Python tuple. The below code snippet finds the maximum Numeric Value within the given arguments. In this example, we used the max function directly inside a print statement. Remember, either you can use the built-in functions like len, max, or your own custom-defined funcs. Generally, the max function key value assigns to a default value. In this section, we discuss how to use this Python max function on Tuple, List, Dictionary, and Sets with practical examples, and its syntax are: # Simple Syntax Or, say, the max function returns the highest, largest, or biggest items in a given object. The Python max function is used to find the maximum item of a given object.
