Currently there is support for two stores: * LevelDB * YugabyteDB ## Usage ``` boostd-data run yugabyte --hosts \ --connect-string \ --addr ``` We recommend creating a systemd file for this service and utilising it to easily start and stop the `boostd-data` service. Please note that this service is an independent process and is not controlled by any other Boost process. {% hint style="info" %} The PGX driver from Yugabyte supports cluster aware Postgres connection out of the box. If you are deploying a multi-node YugabyteDB cluster, then please update your connect-string to use a cluster aware connection. With Cluster Mode: "postgresql://postgres:postgres\@127.0.0.1:5433?load\_balance=true"
With Cluster Mode + No SSL: "postgresql://postgres:postgres\@127.0.0.1:5433?sslmode=disable\&load\_balance=true" {% endhint %} {% hint style="info" %} \--hosts takes the IP addresses of the YugabyteDB YT-Servers.\ Example: \--hosts=10.0.0.1 --hosts=10.0.0.2 --hosts=10.0.0.3 \ \--addr is the \:\ where `boostd-data` service should be listening on. The IP here can be a private one (recommended) and should reachable by all boost related processes. Please ensure to update your firewall configuration accordingly. {% endhint %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://boost.filecoin.io/deployment/boostd-data.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
