Heartbeats are needed to control the WAL disk space consumption in the following cases: We had not enabled heartbeats in Debezium. We added alarms on the RDS metric TransactionLogsDiskUsage and OldestReplicationSlotLag to alert us when the transaction logs disk usage increased above a threshold or when a replication slot started lagging - meaning that Debezium might have died. No alarms were set up on the transaction logs disk usage on the database. "3.14") and set to json to receive HSTORE columns as a JSON string.Īlways ensure basic hygiene checks like database disk usage, transaction logs disk usage and network and disk bandwidth being used for read and write operations. Specifically, set to string to receive NUMERIC, DECIMAL and equivalent types as a string (eg. To convert to a format that’s easier to parse at the expense of some accuracy loss, we configured the data type specific properties as documented. As documented, that’s the default for NUMERIC columns, but can be difficult to handle for consumers. We were observing a few data-types with base64 encoded data. The only downside is that we now need to maintain the schema of those messages in an external schema registry. Hence we decided to disable message schemas by setting and to false to reduce the size of each payload considerably hence saving on network bandwidth and serialization/deserialization costs. We were producing JSON messages with schemas enabled this creates larger Kafka records than needed, in particular if schema changes are rare. This url shows how a user would connect to a PostgreSQL with QGIS using SSH.On PostgreSQL = 10, use the pgoutput plugin. I don’t see anywhere where I would put the hostname for the RDS database like I do in Datagrip and PG Admin.Ĭonnecting QGIS to a Remote PostgreSQL database using an SSH key? is a previous question about the same issue, but I’m not quite sure it’s the same thing I’m trying to do. I don’t really understand this last part though, I don’t even know if it makes sense. Then I would sign into PostgreSQL in QGIS with the database, with localhost and port name from above and the credentials for the RDS database. So I assume the connection coming into my computer will get re-route to my localhost:port. I was reading this article from a previous post and it was talking about port-forwarding. I see no option in there for SSH connections. I read that QGIS does not support SSH connections. How do I get QGIS on my local machine to read and write to that database? Then I use the RDS instance “host name”, “port:5432”, “username” and “password” to the database. I use the EC2 “host name”, “user” and the “pem key” file. So with a local client like DataGrip and PG Admin I can connect to the database no problem. When I created the EC2 instance I also got the pem key. I set an inbound rule in the security group PostgreSQL on port 5432. The RDS instances is only shared with a EC2 (linux) instance. I’m trying to connect a local client (QGIS) to a PostgreSQL database hosted on an RDS instance. I’m still kind of learning and this is new to me so forgive me if I’m using the wrong terminology or wrong tools.
