## Problem Summary:
add rpc avg udaf sample
```
CREATE AGGREGATE FUNCTION rpc_avg(int) RETURNS double PROPERTIES (
"TYPE"="RPC",
"OBJECT_FILE"="127.0.0.1:9000",
"update_fn"="rpc_avg_update",
"merge_fn"="rpc_avg_merge",
"finalize_fn"="rpc_avg_finalize"
);
CREATE TABLE `table1` (
`event_day` date NULL,
`siteid` int(11) NULL DEFAULT "10",
`citycode` smallint(6) NULL,
`username` varchar(32) NULL DEFAULT "",
`pv` bigint(20) SUM NULL DEFAULT "0"
) ENGINE=OLAP
AGGREGATE KEY(`event_day`, `siteid`, `citycode`, `username`)
COMMENT 'OLAP'
DISTRIBUTED BY HASH(`siteid`) BUCKETS 1
PROPERTIES (
"replication_allocation" = "tag.location.default: 1",
"in_memory" = "false",
"storage_format" = "V2"
)
```
import 100w rows data
## result
The performance of calculating the mean value alone is similar to that of
the built-in function
Double the performance loss of the group by scenario
