QUESTION

Are Headless Services updated "atomic" in Kubernetes?

Asked 2021-Apr-15 at 09:31

I am working on a Kubernetes integration of the database Apache IoTDB which supports a Cluster mode. Currently, to start a cluster each node needs to know the IP adresses of all other nodes in its "ensemble" upfront, before starting.

I think the default approach to this in Kubernetes would generally be to use a StatefulSet and a headless Service. And the startup loop I scratched would be something like this

start each pod with a container which contains a "pre-start" script
In the pre-start script wait until all other pods of the set are started and get all their ip adresses from the headless service)
update the configs / env variables with all cluster ip adresses
start the iotdb instance(s)

So the only question I have is for step 2: When do I know that all pods are started? Is the update of the DNS / A records of the headless Service atomic in the sense that I see all pods or no pod? OR do I have to query the API Server separately to see the number of replicas and then wait until I got all their records from the headless service?

Or is there a more kubernetes-like way to achieve that?

Thanks already!

When a DNS address of a headless service is resolved, it returns a list of Pods (ie. IPs) from an underlying endpoint object. The endpoint object always holds the list of Ready pods.

So, you will get the list of Ready pods of that moment on resolving headless service DNS.

How to convert Calcite Logical plan to another data engine's physical plan?

Asked 2019-Dec-10 at 13:45

I am trying to design the relational table structure and standard SQL query for Apache - IoTDB (a time series database) with Calcite. Now I want to know how i can convert Calcite's logical plan to IoTDB own physical plan easily.

For example, I execute a simple query:

The standard way of creating a physical plan for a particular data source is to create an adapter for that data source. This amounts to writing rules which can convert logical operators to physical operators. This allows data sources to specify what logical operators it can implement and how.

Okay I have it, when I run in debug mode, or make a debug app package it loses everything, after generating a release app package it works fine.
