Instance Attribute Details
#data_type_mapping ⇒ Hash<String,String>
Custom data type mapping that builds a mapping from a JDBC data type
to an Glue data type. For example, the option
"dataTypeMapping":\{"FLOAT":"STRING"\}
maps data fields of JDBC
type FLOAT
into the Java String
type by calling the
ResultSet.getString()
method of the driver, and uses it to build
the Glue record. The ResultSet
object is implemented by each
driver, so the behavior is specific to the driver you use. Refer to
the documentation for your JDBC driver to understand how the driver
performs the conversions.

#filter_predicate ⇒ String
Extra condition clause to filter data from source. For example:
BillingCity='Mountain View'
When using a query instead of a table name, you should validate that
the query works with the specified filterPredicate
.

#num_partitions ⇒ Integer
The number of partitions. This value, along with lowerBound
(inclusive) and upperBound
(exclusive), form partition strides for
generated WHERE
clause expressions that are used to split the
partitionColumn
.

#partition_column ⇒ String
The name of an integer column that is used for partitioning. This
option works only when it's included with lowerBound
,
upperBound
, and numPartitions
. This option works the same way as
in the Spark SQL JDBC reader.
