Motivation and Context

Add an API to toggle KV for all merchants

How did you test it?

• Enable KV for all merchants

curl --location 'http://localhost:8080/accounts/kv' \
--header 'Content-Type: application/json' \
--header 'api-key: test_admin' \
--data '{
    "kv_enabled": true
}'

Check if any merchant_account has postgres_only.

SELECT storage_scheme from merchant_account where storage_scheme='postgres_only'

It should return 0 rows

-Disable KV for all merchants

--header 'Content-Type: application/json' \
--header 'api-key: test_admin' \
--data '{
    "kv_enabled": false
}'

Check if any merchant_account has redis_kv

SELECT storage_scheme from merchant_account where storage_scheme='redis_kv'

It should return 0 rows
