Abstract
The subject technology receives a query, the query including a query range for processing the query. The subject technology sends a request to a key-value store for blob metadata and a set of recent writes for the query range. The subject technology receives the blob metadata, the blob metadata including information related to a set of blob files. The subject technology determines whether the set of blob files is stored in a local cache. The subject technology, in response to at least one blob file being missing from the set of blob files, sends a request to a blob store to retrieve the at least one blob file of the set of blob files. The subject technology transforms the retrieved at least one blob file to a column file format. The subject technology stores the transformed at least one blob file in the local cache.
