Heterogenous key-value sets in tree database

A system comprising:

• a memory device;
• and
• a processor operatively coupled to the memory device, the processor being configured to perform operations comprising:
• generating a key-value store tree database on the memory device, the key-value store tree database comprising a multi-level tree that comprises:
• a base level comprising at least one base level node, the at least one base level node comprising a heterogeneous key-value set (kvset), the heterogeneous kvset comprising a first entry for a first key-value store tree and a second entry for a second key-value store tree;
• and
• a first subsequent level comprising:
• a first key-value store tree node comprising a first homogeneous kvset for the first key-value store tree;
• and
• a second key-value store tree node including a second homogeneous kvset for the second key-value store tree, the multi-level tree having a first determinative mapping of entries between the at least one base level node and the first subsequent level, the multi-level tree further having a second determinative mapping of entries between the first subsequent level and a second subsequent level of the multi-level tree;
• and
• searching for one or more keys in the key-value store tree database.

At least one machine readable media including instructions that, when executed by processor, cause the processor to perform operations comprising:

• generating a key-value store tree database on a memory device, the key-value store tree database comprising a multi-level tree that comprises:
• a base level comprising at least one base level node, the at least one base level node comprising a heterogeneous key-value set (kvset), the heterogeneous kvset comprising a first entry for a first key-value store tree and a second entry for a second key-value store tree;
• and
• a first subsequent level comprising:
• a first key-value store tree node comprising a first homogeneous kvset for the first key-value store tree;
• and
• a second key-value store tree node including a second homogeneous kvset for the second key-value store tree, the multi-level tree having a first determinative mapping of entries between the at least one base level node and the first subsequent level, the multi-level tree further having a second determinative mapping of entries between the first subsequent level and a second subsequent level of the multi-level tree;
• and
• searching for one or more keys in the key-value store tree database.
