Installation

Install this library in a virtualenv using pip. virtualenv is a tool to create isolated Python environments. The basic problem it addresses is one of dependencies and versions, and indirectly permissions.

With virtualenv, it’s possible to install this library without needing system install permissions, and without clashing with the installed system dependencies.

pip install virtualenv
virtualenv <your-env>
source <your-env>/bin/activate
<your-env>/bin/pip install langchain-google-datastore

pip install virtualenv
virtualenv <your-env>
<your-env>\Scripts\activate
<your-env>\Scripts\pip.exe install langchain-google-datastore

Document Loader Usage

Use a document loader to load data as LangChain Documents.

from langchain_google_datastore import DatastoreLoader

loader = DatastoreLoader(
    source="MyKind"
)
docs = loader.lazy_load()

See the full Document Loader tutorial.

Chat Message History Usage

Use ChatMessageHistory to store messages and provide conversation history to LLMs.

from langchain_google_datastore import DatastoreChatMessageHistory

history = DatastoreChatMessageHistory(
    session_id="my-session_id",
    kind="HistoryMessages"
)

See the full Chat Message History tutorial.
