RemoteSqlite

RemoteSqlite is a way to easily access a remote Sqlite database and perform queries, including SELECT and INSERT operations

The remote database is referenced through a PyFilesystem2 url, such as:

• osfs://path/to/file
• s3://path/to/file

You can perform pull and push operations that transfer the database to a local temp directory

See below for examples of how to use

from remote_sqlite import RemoteSqlite
db = RemoteSqlite('osfs:///Users/vbalasubramaniam/Downloads/Northwind_large.sqlite', always_download=True)
db.get_counts()
