Speed Up the Leaderboard #60
Conversation
- Changed the leaderboard to use heap-sort instead of dumping the data and then sorting - Batch queried all data used by ParseAndExecute, heavily speeding up the leaderboard
WalkthroughThe changes involve significant enhancements to data retrieval and query processing across the codebase. Key modifications include the introduction of batch retrieval methods for nodes and caches, optimizations of the Changes

queryHeapusingheap.Initis necessary for managing heap operations.The code changes are approved.
70-70: LGTM!The additional parameters in the
ParseAndExecutecall allow for more informed decision-making during query execution.The code changes are approved.
75-77: LGTM!Using a heap structure for sorting queries based on the length of their outputs is efficient.
The code changes are approved.
80-83: LGTM!Popping elements from the heap ensures that the queries are ordered correctly based on their output lengths.
The code changes are approved.
125-142: LGTM!Encapsulating heap operations within the
queryHeaptype enhances code readability and maintainability.The code changes are approved.
pkg/graph/mockGraph.go (1)
145-159: LGTM!The
GetCachesmethod is correctly implemented and enhances the functionality ofMockStorageby allowing retrieval of multiple caches based on their IDs.The code changes are approved.
pkg/graph/parser.go (6)
10-11: LGTM!The additional parameters in the
ParseAndExecutefunction signature allow for more complex operations involving node management and caching.The code changes are approved.
15-18: LGTM!The
nameToIDsmapping facilitates the retrieval of node IDs based on their names, streamlining the process of querying dependents and dependencies.The code changes are approved.
52-73: LGTM!The handling of tokens prefixed with "dependents" or "dependencies" introduces a more structured approach to managing node relationships.
The code changes are approved.
76-83: LGTM!Utilizing batch queries for dependents and dependencies reduces the number of individual queries made to the storage backend, improving performance.
The code changes are approved.
112-113: LGTM!Filtering nodes based on their type ensures that only relevant nodes are included in the query results.
The code changes are approved.
