Description

If you configure high number of partitions, a Mapping Configuration task might fail with the following memory buffer error:
MAPPING> JAVA PLUGIN_1762 [2016-09-23 01:35:29.259] [ERROR] java.lang.OutOfMemoryError: Direct buffer memory
MAPPING> CMN_1761 [2016-09-23 01:35:29.259] Timestamp Event: [Fri Sep 23 01:35:29 2016]
The recommended maximum number of partitions is 32.
CON-4047
A Mapping Configuration task fails if partitioning is enabled and the key range contains a string value with a single quote.
CON-3158
The Data Synchronization and Mapping Configuration tasks that use a filter or query in which the where clause for which the value provided has a single quote fails.
CON-454
If you use Amazon Redshift source objects with more than two levels of relationships in a Data Synchronization task, the Refresh Fields option does not display the metadata for those objects. You can save and run the task, but the task fails at run time.
Workaround: Create a new Data Synchronization task that contain objects with two or less than two levels of relationships, or use the mapping configuration task.
