Hi,
I'm using postgresql10.5 with 1 master node and 2 slaves.
Each of node is having following specs
# DB Version: 10.5
# OS Type: CentOS 7
# Total Memory (RAM): 32 GB
# CPUs num: 24
# Data Storage: ssd
https://pgtune.leopard.in.ua suggested me tuning config as below
max_connections = 200
shared_buffers = 8GB
effective_cache_size = 24GB
maintenance_work_mem = 2GB
checkpoint_completion_target = 0.7
wal_buffers = 16MB
default_statistics_target = 100
random_page_cost = 1.1
effective_io_concurrency = 200
work_mem = 699kB
min_wal_size = 1GB
max_wal_size = 2GB
max_worker_processes = 24
max_parallel_workers_per_gather = 12
max_parallel_workers = 24
I have two questions regarding this
1. What changes do I have to do if I add more standbys or it will be same over all servers?
2. How to select a value for max_connections based on the fact I have 3 servers with same specs and client will using it for read operations only and data is loaded once a month.
Happy to help :)
