UPDATE is equivalent to DELETE + INSERT in Postgres

Postgres is a transactional database that uses MVCC to ensure consistency while enabling concurrent data access. As a result, when you update a record, the old version of the record is marked as deleted, and a new version is created.

Check the picture:

* First, we insert a record with 'John'. It's placed in storage at the offset (0,1). The value in xmin is the ID of the transaction that created this record version (806).

* Next, we update the record's name to 'Tom'. This transaction deletes the previous version (xmax=808) and inserts a new one (xmin=808) at the offset (0,2).

I showcased Apache Pinot, Kafka and Apache Superset on my local K8s on my laptop, running realtime data analytics via Kafka to Pinot and viewable as a chart in Superset.

All this live coding in about 40 minutes. Best feeling ever!

First rule of database design I learned more than 20 years ago: never use the BOOL column type, use a CHAR(1) instead.

At one point, it will evolve into more than 2 values and you'll be faced with a painful migration.

Every boolean method parameter is an enum hiding in disguise.

It's really good idea to test your application and you don't need additional infra to test you can use #Kafka #Docker and test your application. #DockerCompose is your friend, if you need to learn how it's done, join @DelhiJUG session with @KoTurk77 https://t.co/ooAPPLZxLV

[Vikas Malik @_vikasM]

@intellijidea is your friend when you are working with #Kafka Learn how to use it from @KoTurk77

[Vikas Malik @_vikasM]

Let's get our hands dirty and do some live coding
