Hi
@Gopi Bathala, Thank you for your interest in Pinot. Please see the answer to your questions below:
1 & 2: Pinot has a Go client which allows user to query a table in Pinot (
https://github.com/startreedata/pinot-client-go). However, being able to write to a Pinot table is currently not supported.
3. StarTree provides a managed version of Pinot which allows customers to focus on building Apps while their infra is managed by StarTree. There are some additional features provided by StarTree as well (
https://startree.ai/advantages).
There is a project Write API, which will provide an endpoint to which applications can write data to. If you are interested in learning more, please let me know. I will set up a call to chat about it.
