### Account indexing
As the number of populated accounts on the cluster grows, account-data RPC
requests that scan the entire account set -- like
[`getProgramAccounts`](developing/clients/jsonrpc-api.md#getprogramaccounts) and
[SPL-token-specific requests](developing/clients/jsonrpc-api.md#gettokenaccountsbydelegate) --
may perform poorly. If your validator needs to support any of these requests,
you can use the `--account-index` parameter to activate one or more in-memory
account indexes that significantly improve RPC performance by indexing accounts
by the key field. Currently supports the following parameter values:
- `program-id`: each account indexed by its owning program; used by [`getProgramAccounts`](developing/clients/jsonrpc-api.md#getprogramaccounts)
- `spl-token-mint`: each SPL token account indexed by its token Mint; used by [getTokenAccountsByDelegate](developing/clients/jsonrpc-api.md#gettokenaccountsbydelegate), and [getTokenLargestAccounts](developing/clients/jsonrpc-api.md#gettokenlargestaccounts)
- `spl-token-owner`: each SPL token account indexed by the token-owner address; used by [getTokenAccountsByOwner](developing/clients/jsonrpc-api.md#gettokenaccountsbyowner), and [`getProgramAccounts`](developing/clients/jsonrpc-api.md#getprogramaccounts) requests that include an spl-token-owner filter.
