A simple solution that has very good documentation and low research consumption
LanceDB is deployed on-cloud in our organization. I have only utilized the community-specific version. They have a server-client version that might actually be useful for a lot of other people. I just needed the direct one, which works quite well for me. I don't know how good the server client version is yet. Overall, I rate LanceDB a nine out of ten.

Real-time data capture optimizes database performance but Views create problems
One of the most valuable features is real-time data capture; it optimizes database performance. I think using real-time data capture reduces job running time and the amount of data sent at once with batch loads. Replicating the same data daily isn't optimal, so real-time reception improves application performance and reduces latency.

What do you like most about PostgreSQL?
It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping.
What is your experience regarding pricing and costs for PostgreSQL?
The tool is free of cost. For now, it's not about making money. But once we perfect it, we can offer it to customers willing to pay for support and other services. Most of my deployments are free.
