| 1072435124 | I_kwDOCGYnMM4_7A-0 | 350 | Optional caching mechanism for table.lookup() | 9599 | open | 0 | 3 | 2021-12-06T17:54:25Z | 2021-12-06T17:56:57Z | OWNER | Inspired by work on `git-history` where I used this pattern: ```python column_name_to_id = {} def column_id(column): if column not in column_name_to_id: id = db["columns"].lookup( {"namespace": namespace_id, "name": column}, foreign_keys=(("namespace", "namespaces", "id"),), ) column_name_to_id[column] = id return column_name_to_id[column] ``` If you're going to be doing a large number of `table.lookup(...)` calls and you know that no other script will be modifying the database at the same time you can presumably get a big speedup using a Python in-memory cache - maybe even a LRU one to avoid memory bloat. | 140912432 | issue | {"url": "https://api.github.com/repos/simonw/sqlite-utils/issues/350/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} |
