- ["slug" being an entity attribute] Spring Data offers an existsBy query method, which we can define in the PostRepository, as follows: 1 2 3 4 5 6 @Repository public interface PostRepository extends JpaRepository<Post, Long> { boolean existsBySlug(String slug); } [another] option to emulate existence is using a CASE WHEN EXISTS native SQL query: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 @Repository public interface PostRepository extends JpaRepository<Post, Long> { @Query(value = """ SELECT CASE WHEN EXISTS ( SELECT 1 FROM post WHERE slug = :slug ) THEN 'true' ELSE 'false' END """, nativeQuery = true ) boolean existsBySlugWithCase(@Param("slug") String slug); }
- A very common workflow is to index some data based on its embeddings and then given a new query embedding retrieve the most similar examples with k-Nearest Neighbor search. For example, you can imagine embedding a large collection of papers by their abstracts and then given a new paper of interest retrieve the most similar papers to it. TLDR in my experience it ~always works better to use an SVM instead of kNN, if you can afford the slight computational hit

- pgloader will keep a separate file of rejected data, but continue trying to copy good data in your database. pgloader also implements data reformatting, a typical example of that being the transformation of MySQL datestamps 0000-00-00 and 0000-00-00 00:00:00 to PostgreSQL NULL value
- A SequenceInputStream represents the logical concatenation of other input streams. It starts out with an ordered collection of input streams and reads from the first one until end of file is reached, whereupon it reads from the second one, and so on, until end of file is reached on the last of the contained input streams.
