Abstract: Methods, systems, and devices for techniques to group media blocks are described. In some cases, a computing system may generate a memory map for a preconfigured size or chunk of data. For example, the computing system may divide files of media blocks into a set of fixed sized chunks of consecutive media blocks. Upon an application requesting a memory map for a set of media blocks, a storage layer of the computing system may generate a sub-map of the memory map for each chunk of data containing a media block of the set of requested media blocks. In some cases, the computing system may assign the chunks of data a continuous range of addresses in the virtual address space of the application. Upon generating the memory map, the storage layer may return an indication of the virtual address ranges of the requested media blocks to the application.

Abstract: Methods, systems, and devices for techniques to balance log structured merge trees are described. A computing system may rebalance a tree structure having an ordered set of leaf nodes by splitting or joining leaf nodes of the tree structure. To split a leaf node, the computing system may select a key to evenly partition key and value data stored in the leaf. The computing system may place each key block of the leaf node having keys less than or equal to the selected key in a first new leaf node, and may place each key block of the leaf node having keys greater than the selected key in a second new leaf node. To join leaf nodes of the tree structure, the computing system may place each key block and each value block of the leaf node and the adjacent leaf node in a new leaf node.
