API Key Partitioning
API Key Partitioning is the strategy of using multiple API keys to distribute request volume across different endpoints or sub-accounts. This technique helps to circumvent rate limits that are often applied on a per-key basis.
By segregating different strategies or asset classes onto separate keys, a trader can ensure that a surge in one area does not impact the execution of another. It also provides a layer of isolation, where issues with one key do not necessarily stop all trading activity.
This requires careful management of key permissions and monitoring across the entire infrastructure. API key partitioning is a common practice for large-scale operations managing diverse portfolios.
