To enhance your DataSync integration for  Parquet , you can configure the Parquet Bulk Load  Meshlet  to the directives listed below.  To check out the general meshlet configurations, see  General Meshlet Configurations for DataSync . Directive Default Value Description maxFileSize Required Configuration.  This configuration specifies the max size of records for each parquet file.  10000  will be used if input is over  10000  to prevent possible performance and memory issues. A suggested value is  5000 .   NOTE : Negative values are not supported and will result in 1 record for each parquet file.  perspectium:

To access the URL, go to Azure Portal > Sto rage Account > Access Keys > Show Keys > Connection String. perspectium:  
	azure:    
    	connectionString: DefaultEndpointsProtocol=.....EndpointSuffix=core.windows.net destinationContainer Name of your Azure Blob Storage container, including subdirectories if desired, to specify where the records will be uploaded e.g. container/folder1/folder2.   For example,  the following will save records into the pspcontainer blob storage container: perspectium:  
	azure:    
		destinationContainer: pspcontainer If the following is configured: perspectium:  
	azure:    
		destinationContainer: pspcontainer/tables/$table If an incident record is being processed and uploaded to the Azure Blob Storage container, then the record will be saved in the pspcontainer container and in the /tables/incident directory in that container, creating the directoriy incident automatically.  NOTE : Adding the  $table  token indicates this token will be replaced by the table name of the record. To enable the sharing of Parquet files to Azure, the spring profile will need to include azure:  java -jar -Dspring.profiles.active=dev,azure
