+As a technique for query acceleration, Pre-aggregate tables cannot be queried 
directly. 
 Queries are to be made on main table. While doing query planning, internally 
CarbonData will check 
 associated pre-aggregate tables with the main table, and do query plan 
transformation accordingly.

Whether use YARN local directories for multi-table load disk load balance | If 
this is set it to true CarbonData will use YARN local directories for 
multi-table load disk load balance, that will improve the data load 
performance. |
   | carbon.use.multiple.temp.dir | spark/carbonlib/carbon.properties | Data 
loading | Whether to use multiple YARN local directories during table data 
loading for disk load balance | After enabling 'carbon.use.local.dir', if this 
is set to true, CarbonData will use all YARN local directories during data load 
for disk load balance, that will improve the data load performance. Please 
enable this property when you encounter disk hotspot problem during data 
loading. |
   | carbon.sort.temp.compressor | spark/carbonlib/carbon.properties | Data 
loading | Specify the name of compressor to compress the intermediate sort 
temporary files during sort procedure in data loading. | The optional values 
are 'SNAPPY','GZIP','BZIP2','LZ4' and empty. By default, empty means that 
Carbondata will not compress the sort temp files. This parameter will be useful 
if you encounter disk bottleneck. |
+  | carbon.load.skewedDataOptimization.enabled | 
spark/carbonlib/carbon.properties | Data loading | Whether to enable size based 
block allocation strategy for data loading. | When loading, carbondata will use 
file size based block allocation strategy for task distribution. It will make 
sure that all the executors process the same size of data -- It's useful if the 
size of your input data files varies widely, say 1MB~1GB. |
 
   Note: If your CarbonData instance is provided only for query, you may 
specify the property 'spark.speculation=true' which is in conf directory of 
spark.
