@ -4,6 +4,16 @@ Overview
This project is about streaming Solana account updates for a specific program
into other databases or event queues.
Having an up to date version of all account data data in a database is
particularly useful for queries that need access to all accounts. For example,
retrieving the addresses of Mango Markets accounts with the largest unrealized
PnL goes from "getProgramAccounts from a Solana node for 50MB of data and compute
locally (3-10s total)" to "run a SQL query (150ms total)".
The database could also be used as a backend for serving `getMultipleAccounts`
and `getProgramAccounts` queries generally. That would reduce load on Solana RPCt
nodes while decreasing response times.
Supported Solana sources:
- AccountsDB plugin (preferred) plus JSONRPC HTTP API (for initial snapshots)
