Import of declarative_base when SQLAlchemy <1.4 ( #883 )
...
In
[pyproject.toml](https://github.com/hwchase17/langchain/blob/master/pyproject.toml ),
the expectation is `SQLAlchemy = "^1"`. But, the way `declarative_base`
is imported in
[cache.py](https://github.com/hwchase17/langchain/blob/master/langchain/cache.py )
will only work with SQLAlchemy >=1.4. This PR makes sure Langchain can
be run in environments with SQLAlchemy <1.4

Add Redis cache implementation ( #397 )
...
I'm using a hash function for the key just to make sure its length
doesn't get out of hand, otherwise the implementation is quite similar.

add sqlalchemy generic cache ( #361 )
...
Created a generic SQLAlchemyCache class to plug any database supported
by SQAlchemy. (I am using Postgres).
I also based the class SQLiteCache class on this class SQLAlchemyCache.
As a side note, I'm questioning the need for two distinct class
LLMCache, FullLLMCache. Shouldn't we merge both ?
