Feature: standby cluster
|

Scenario: check permanent logical slots are preserved on failover/switchover
|
|
Given I start postgres1
|
|
Then postgres1 is a leader after 10 seconds
|
|
And I sleep for 3 seconds
|
|
When I issue a PATCH request to http://127.0.0.1:8009/config with {"loop_wait": 2, "slots": {"pm_1": {"type": "physical"}}, "postgresql": {"parameters": {"wal_level": "logical"}}}
|
|
Then I receive a response code 200
|
|
And Response on GET http://127.0.0.1:8009/config contains slots after 10 seconds
|
|
And I sleep for 3 seconds
|
|
When I issue a PATCH request to http://127.0.0.1:8009/config with {"slots": {"test_logical": {"type": "logical", "database": "postgres", "plugin": "test_decoding"}}}
|
|
Then I receive a response code 200
|
|
And I do a backup of postgres1
|
|
When I start postgres0 with callback configured
|
|
Then "members/postgres0" key in DCS has state=running after 10 seconds
|
|
And replication works from postgres1 to postgres0 after 15 seconds
|
|
When I shut down postgres1
|
|
Then postgres0 is a leader after 10 seconds
|
|
And "members/postgres0" key in DCS has role=master after 3 seconds
|
|
When I issue a GET request to http://127.0.0.1:8008/
|
|
Then I receive a response code 200
|
|
And there is a label with "test_logical" in postgres0 data directory
|
|
|
|
Scenario: check replication of a single table in a standby cluster
|
|
Given I start postgres1 in a standby cluster batman1 as a clone of postgres0
|
|
Then postgres1 is a leader of batman1 after 10 seconds
|
|
When I add the table foo to postgres0
|
|
Then table foo is present on postgres1 after 20 seconds
|
|
When I issue a GET request to http://127.0.0.1:8009/master
|
|
Then I receive a response code 200
|
|
When I issue a GET request to http://127.0.0.1:8009/standby_leader
|
|
Then I receive a response code 200
|
|
And I receive a response role standby_leader
|
|
And there is a postgres1_cb.log with "on_start replica batman1\non_role_change standby_leader batman1" in postgres1 data directory
|
|
When I start postgres2 in a cluster batman1
|
|
Then postgres2 role is the replica after 24 seconds
|
|
And table foo is present on postgres2 after 20 seconds
|
|
|
|
Scenario: check failover
|
|
When I kill postgres1
|
|
And I kill postmaster on postgres1
|
|
Then postgres2 is replicating from postgres0 after 32 seconds
|
|
When I issue a GET request to http://127.0.0.1:8010/master
|
|
Then I receive a response code 200
|
|
When I issue a GET request to http://127.0.0.1:8010/standby_leader
|
|
Then I receive a response code 200
|
|
And I receive a response role standby_leader
|
|
And replication works from postgres0 to postgres2 after 15 seconds
|
|
And there is a postgres2_cb.log with "on_start replica batman1\non_role_change standby_leader batman1" in postgres2 data directory
