Please answer these questions before submitting your issue. Thanks!

1. What did you do?

Change few configs then start a new PD cluster. But some config are not taking effect.

Config file:

# PD Configuration
initial-cluster-state = "new"

enable-prevote = true
lease = 3
namespace-classifier = "table"
tso-save-interval = "3s"

[security]
cacert-path = ""
cert-path = ""
key-path = ""

[log]
level = "info"

[log.file]

[metric]

[schedule]
leader-schedule-limit = 4
max-merge-region-keys = 0
max-merge-region-size = 0
max-pending-peer-count = 16
max-snapshot-count = 3
max-store-down-time = "3000h"
merge-schedule-limit = 0
region-schedule-limit = 0
replica-schedule-limit = 0
split-merge-interval = "1h"
tolerant-size-ratio = 5.0

[replication]
location-labels = []
max-replicas = 1
