测试
初始100亿数据
使用pgbench 初始化100亿tpcb测试数据。
man pgbench
-i
--initialize
Required to invoke initialization mode.
-I init_steps
--init-steps=init_steps
Perform just a selected set of the normal initialization steps.
init_steps specifies the initialization steps to be performed,
using one character per step. Each step is invoked in the specified order.
The default is dtgvp.
The available steps are:
d (Drop)
Drop any existing pgbench tables.
t (create Tables)
Create the tables used by the standard pgbench scenario,
namely pgbench_accounts, pgbench_branches, pgbench_history,
and pgbench_tellers.
g (Generate data)
Generate data and load it into the standard tables,
replacing any data already present.
v (Vacuum)
Invoke VACUUM on the standard tables.
p (create Primary keys)
Create primary key indexes on the standard tables.
f (create Foreign keys)
Create foreign key constraints between the standard tables.
(Note that this step is not performed by default.)
初始化
pgbench -i -s 100000 -I dtg -n --tablespace=tbs2

创建索引
1、强制设置并行度为24，a,b,c,d取最小
alter table pgbench_accounts set (parallel_workers =32); # a
max_worker_processes = 128 # b
max_parallel_maintenance_workers = 24 # c
max_parallel_workers = 64 # d
max_parallel_workers_per_gather = 0
min_parallel_table_scan_size=0
min_parallel_index_scan_size=0
parallel_setup_cost=0
parallel_tuple_cost=0
2、创建tpcb数据表索引，100亿记录，创建索引耗时44分钟。
pgbench -i -I p --index-tablespace=tbs1
