Class GetPartitionsRequest

    • Method Detail

      • catalogId

        public final String catalogId()

        The ID of the Data Catalog where the partitions in question reside. If none is provided, the Amazon Web Services account ID is used by default.

        Returns:
        The ID of the Data Catalog where the partitions in question reside. If none is provided, the Amazon Web Services account ID is used by default.
      • databaseName

        public final String databaseName()

        The name of the catalog database where the partitions reside.

        Returns:
        The name of the catalog database where the partitions reside.
      • tableName

        public final String tableName()

        The name of the partitions' table.

        Returns:
        The name of the partitions' table.
      • expression

        public final String expression()

        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.

        (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.

        Sample API Call:

      • nextToken

        public final String nextToken()

        A continuation token, if this is not the first call to retrieve these partitions.

        Returns:
        A continuation token, if this is not the first call to retrieve these partitions.
      • segment

        public final Segment segment()

        The segment of the table's partitions to scan in this request.

        Returns:
        The segment of the table's partitions to scan in this request.
      • maxResults

        public final Integer maxResults()

        The maximum number of partitions to return in a single response.

        Returns:
        The maximum number of partitions to return in a single response.
      • excludeColumnSchema

        public final Boolean excludeColumnSchema()

        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.

        Returns:
        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.

      • queryAsOfTime

        public final Instant queryAsOfTime()

        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.

        Returns:
        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.
      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
