Directing requests to databases based on client account association

A method, comprising:

• determining a first client account associated with a first request to perform a first transaction;
• determining a second client account associated with a second request to perform a second transaction;
• selecting, for the first request, a primary deployment that stores a first dataset responsive to determining the first client account associated with the first request;
• selecting, for the second request, a secondary deployment that stores a second dataset that comprises the first dataset responsive to determining the second client account associated with the second request;
• and
• executing, while the primary deployment and the secondary deployment are both available, the first transaction on the first dataset at the primary deployment and the second transaction on the second dataset at the secondary deployment.

A non-transitory computer readable storage media comprising instructions that, when executed by a processor, cause the processor to:

• determine a first client account associated with a first request to perform a first transaction;
• determine a second client account associated with a second request to perform a second transaction;
• select, for the first request, a primary deployment that stores a first dataset responsive to determining the first client account associated with the first request;
• select, for the second request, a secondary deployment that stores a second dataset that comprises the first dataset responsive to determining the second client account associated with the second request;
• and
• execute, while the primary deployment and the secondary deployment are both available, the first transaction on the first dataset at the primary deployment and the second transaction on the second dataset at the secondary deployment.
