Abstract

Techniques are described for fast large file truncation. An example method includes receiving, by a data platform, a request to truncate a file, wherein data of the file is stored in a tree data structure including a plurality of nodes with leaf nodes corresponding to data of the file; determining a first node of the plurality of nodes including a plurality of child nodes; determining, based on a maximum key, a subset of the child nodes corresponding to a portion of the data that is to be retained; based on determining not to traverse the first node, updating a second node that is a parent of the first node to include a pointer to each child node of the subset of child nodes; and moving, from a subset of leaf nodes referenced by the subset of child nodes, a leaf node to rebalance the tree data structure.
