#### Parseable
[Parseable](https://www.parseable.io) is a distributed log analytics database that provides SQL-like query interface for log data. The recommended connector library is [sqlalchemy-parseable](https://github.com/parseablehq/sqlalchemy-parseable).
The connection string is formatted as follows:
```
parseable://<username>:<password>@<hostname>:<port>/<stream_name>
```
For example:
```
parseable://admin:admin@demo.parseable.com:443/ingress-nginx
```
Note: The stream_name in the URI represents the Parseable logstream you want to query. You can use both HTTP (port 80) and HTTPS (port 443) connections.
#### Apache Pinot
