2021/11/30 - AWS Glue - 7 updated api methods
Changes Support for DataLake transactions
{'TransactionId': 'string'}
Deletes multiple tables at once.
Note
After completing this operation, you no longer have access to the table versions and partitions that belong to the deleted table. Glue deletes these "orphaned" resources asynchronously in a timely manner, at the discretion of the service.
To ensure the immediate deletion of all related resources, before calling BatchDeleteTable , use DeleteTableVersion or BatchDeleteTableVersion , and DeletePartition or BatchDeletePartition , to delete any resources that belong to the table.

TableName='string',
Expression='string',
NextToken='string',
Segment={
'SegmentNumber': 123,

string
[REQUIRED]
The name of the catalog database where the partitions reside.
string
[REQUIRED]
The name of the partitions' table.
string
An expression that filters the partitions to be returned.
The expression uses SQL syntax similar to the SQL WHERE filter clause. The SQL statement parser JSQLParser parses the expression.
Operators : The following are the operators that you can use in the Expression API call:
=
Checks whether the values of the two operands are equal; if yes, then the condition becomes true.
Example: Assume 'variable a' holds 10 and 'variable b' holds 20.
(a = b) is not true.
< >
Checks whether the values of two operands are equal; if the values are not equal, then the condition becomes true.
Example: (a < > b) is true.
>
Checks whether the value of the left operand is greater than the value of the right operand; if yes, then the condition becomes true.
Example: (a > b) is not true.
<
Checks whether the value of the left operand is less than the value of the right operand; if yes, then the condition becomes true.
Example: (a < b) is true.
>=
Checks whether the value of the left operand is greater than or equal to the value of the right operand; if yes, then the condition becomes true.
Example: (a >= b) is not true.
<=
Checks whether the value of the left operand is less than or equal to the value of the right operand; if yes, then the condition becomes true.
Example: (a <= b) is true.
AND, OR, IN, BETWEEN, LIKE, NOT, IS NULL
Logical operators.
Supported Partition Key Types : The following are the supported partition keys.
string
date
timestamp
int
bigint
long
tinyint
smallint
decimal
If an type is encountered that is not valid, an exception is thrown.
The following list shows the valid operators on each type. When you define a crawler, the partitionKey type is created as a STRING , to be compatible with the catalog partitions.
Sample API Call :
string
A continuation token, if this is not the first call to retrieve these partitions.
dict
The segment of the table's partitions to scan in this request.
SegmentNumber (integer) -- [REQUIRED]
The zero-based index number of the segment. For example, if the total number of segments is 4, SegmentNumber values range from 0 through 3.
TotalSegments (integer) -- [REQUIRED]
The total number of segments.
integer
The maximum number of partitions to return in a single response.
boolean
When true, specifies not returning the partition column schema. Useful when you are interested only in other partition attributes such as partition values or location. This approach avoids the problem of a large response by not returning duplicate data.
string
The transaction ID at which to read the partition contents.
datetime
The time as of when to read the partition contents. If not set, the most recent transaction commit time will be used. Cannot be specified along with TransactionId .
