8、4 解决方式

集群的架构

序列	数据库	服务器	segment	master	访问端口
1	Greenplum6.0.0	sdw2	16 primary + 16 mirror	sdw3	5432
2		sdw3
3		sdw4
4	matrixdb4.2	sdw5	16 primary + 16 mirror	sdw7	5432

1、构造测试的数据

# 造10列100w设备的数据
time ./tsbs_generate_data --format="matrixdb" --use-case="massiveiot" --scale="1000000" --log-interval=60s --column-data-type=simple --point-type=int --columns-per-row=10 --timestamp-start="2016-01-01T00:00:00Z" --timestamp-end="2016-01-01T02:00:00Z" > /data/c1/cpu_10_100w.csv
 
# 造50列100w设备的数据
time ./tsbs_generate_data --format="matrixdb" --use-case="massiveiot" --scale="1000000" --log-interval=60s --column-data-type=simple --point-type=int --columns-per-row=50 --timestamp-start="2016-01-01T00:00:00Z" --timestamp-end="2016-01-01T02:00:00Z" > /data/c1/cpu_50_100w.csv
 
# 造100列100w设备的数据
time ./tsbs_generate_data --format="matrixdb" --use-case="massiveiot" --scale="1000000" --log-interval=60s --column-data-type=simple --point-type=int --columns-per-row=100 --timestamp-start="2016-01-01T00:00:00Z" --timestamp-end="2016-01-01T02:00:00Z" > /data/c1/cpu_100_100w.csv

2、查看数据的大小和行数

$ du -sh cpu_10_100w.csv
15G     cpu_10_100w.csv
 
$ du -sh cpu_50_100w.csv
63G     cpu_50_100w.csv
 
$ du -sh cpu_100_100w.csv
122G    cpu_100_100w.csv
 
 
$ wc -l cpu_10_100w.csv
120000000 cpu_10_100w.csv
 
$ wc -l cpu_50_100w.csv
120000000 cpu_50_100w.csv
 
$ wc -l cpu_100_100w.csv
120000000 cpu_100_100w.csv

3、创建表语句

# 创建创建表的function
create or replace function f(name, int, text) returns void as $$   
declare   
  res text := 'ts varchar(50),tag_id integer,';   
begin   
  for i in 1..$2 loop 
  res := res||'c'||i||' integer,';   
  end loop;   
  res := rtrim(res, ',');   
  if $3 = 'ao_col' then   
    res := 'create table '||$1||'('||res||') with(appendonly=true, compresstype=zstd, orientation=column) DISTRIBUTED BY (tag_id)';   
  elsif $3 = 'ao_row' then   
    res := 'create table '||$1||'('||res||') with(appendonly=true, blocksize=262144, orientation=row) DISTRIBUTED BY (tag_id)';   
  elsif $3 = 'heap_row' then   
    res := 'create table '||$1||'('||res||') with(appendonly=false) DISTRIBUTED BY (tag_id)';   
  else   
    raise notice 'use ao_col, ao_row, heap_row as $3';   
    return;   
  end if;   
  execute res;   
end;   
$$ language plpgsql;

   done
done

4、查看创建后的表

# \\dt*
                          List of relations
 Schema |       Name        | Type  |  Owner  |       Storage
--------+-------------------+-------+---------+----------------------
 public | cpu_100_100w_ao   | table | mxadmin | append only
 public | cpu_100_100w_aoco | table | mxadmin | append only columnar
 public | cpu_100_100w_heap | table | mxadmin | heap
 public | cpu_10_100w_ao    | table | mxadmin | append only
 public | cpu_10_100w_aoco  | table | mxadmin | append only columnar
 public | cpu_10_100w_heap  | table | mxadmin | heap
 public | cpu_50_100w_ao    | table | mxadmin | append only
 public | cpu_50_100w_aoco  | table | mxadmin | append only columnar
 public | cpu_50_100w_heap  | table | mxadmin | heap

5、编写mxgate同步脚本

以下脚本可以同步不同的表类型，heap、ao、aoco、分区表等

$  vim sync_mxgate.sh
 
#!bin/bash
 
mxgate --source transfer \\
       --src-host 192.168.***.** \\
       --src-port 5432 \\
       --src-db postgres \\
       --src-user gpadmin \\
       --src-password  gpadmin \\
       --src-schema public \\
       --src-table cpu_100_100w_heap \\
       --compress "lz4" \\
       --local-ip 192.168.***.*** \\
       --db-database postgres \\
       --db-master-port 5432 \\
       --db-user mxadmin \\
       --db-password mxadmin \\
       --target public.cpu_100_100w_heap \\
       --format csv \\
       --parallel 300 \\
       --interval 100  \\
       --stream-prepared 6 \\
       --time-format raw

6、编写gpcopy同步脚本

gpcopy --source-host 192.168.***.*** \\
        --source-port 5432 \\
        --source-user gpadmin \\
        --include-table postgres.public.cpu_100_100w_heap \\
        --dest-host 192.168.***.*** \\
        --dest-port 5432 \\
        --dest-user mxadmin \\
        --drop --exclude-table postgres.public.cpu_100_100w_heap \\
        --jobs 200 /
        --on-segment-threshold 90000

7、查看硬件资源

7、1 CPU和内存信息

7、2 网络信息

8、常见问题总结

8、1 slice bounds out of range

20211021:10:42:20 gpcopy:mxadmin:sdw7:026691-[INFO]:-Copy Timestamp = 20211021104220
20211021:10:42:20 gpcopy:mxadmin:sdw7:026691-[INFO]:-pg_dump (PostgreSQL) 12

20211021:10:42:21 gpcopy:mxadmin:sdw7:026691-[WARNING]:-pg_dump version is higher than source cluster, which might have compatibility issues
20211021:10:42:21 gpcopy:mxadmin:sdw7:026691-[ERROR]:-Caught an error: or: slice bounds out of range
20211021:10:42:21 gpcopy:mxadmin:sdw7:026691-[INFO]:-------------------------------------------------

20211021:10:42:21 gpcopy:mxadmin:sdw7:026691-[INFO]:-Copied 0 databases

8、2 "gpcopy_temp_3" does not exist


failed to stop daemon on segments. pq: relation "gpcopy_temp_6" does not exist
Error: pq: relation "gpcopy_temp_3" does not exist

8、3 Control connection pair should call `InitConnections` first

20211025:13:32:01 gpcopy:mxadmin:sdw7:162638-[ERROR]:-Caught an error: or: slice bounds out of range [62:40]
20211025:13:32:01 gpcopy:mxadmin:sdw7:162638-[INFO]:-------------------------------------------------
20211025:13:32:01 gpcopy:mxadmin:sdw7:162638-[INFO]:-Total elapsed time: 74.028874ms
20211025:13:32:01 gpcopy:mxadmin:sdw7:162638-[INFO]:-Total transferred data 0B, transfer rate 0B/h
20211025:13:32:01 gpcopy:mxadmin:sdw7:162638-[INFO]:-Copied 0 databases
20211025:13:32:01 gpcopy:mxadmin:sdw7:162638-[WARNING]:-Encountered an error during cleanup: Control connection pair should call `InitConnections` first.

8、4 解决方式

1、检查greenplum和matrix的版本信息时候一致，因为gpcopy会校验版本

2、修改version信息需要在postgresql数据库下进行

3、替换一下红色的部门即可

CREATE OR REPLACE FUNCTION pg_catalog.version() RETURNS TEXT
AS $$
SELECT 'PostgreSQL 9.4.20 (Greenplum Database 6.0.0-beta.1 build commit:067fb8e43115bb087c872ee3d2269d869430263d) on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 6.4.0, 64-bit compiled on Mar 19 2019 01:25:00';
