The subject technology receives a query. The subject technology generates a set of query blocks based on parsing the query. The subject technology stores query block metadata for each query block from the set of query blocks. The subject technology restores a set of logical query block boundaries. The subject technology performs a hash-based query block matching. The subject technology generates, after performing the hash-based query block matching, a final query plan. In an example, if a (same) query is executed again the same logical query blocks would produce the same metadata (e.g., identifier, name and hash). This metadata can be used to match logical query blocks between multiple executions of the same query.
