Bounded Hops, Not Blind Ones: Variable-Length Paths in Neo4j Cypher
Cypher's variable-length path patterns answer 'what's connected within N hops' in one line — but the hop bound and relationship-type filter are what stand between a fast query and a full-graph scan.
How can I efficiently paginate large result sets using LIMIT and OFFSET in PostgreSQL while ensuring consistent ordering?
I need to retrieve pages of data from a very large table without scanning the entire dataset on each request. The goal is to bound the query so that only the required subset of rows is processed, while keeping response times predictable. I plan to use the LIMIT and OFFSET clauses (or their MongoDB equivalents) to implement pagination, but I am uncertain abou
embeddedcWhen does Hibernate’s setFirstResult cause excessive row scanning that degrades pagination performance?
The goal is to identify the practical offset size at which Hibernate’s setFirstResult forces the database to scan rows up to the offset instead of using an index seek, and to evaluate how this performance penalty compares with cursor‑based pagination that uses a unique identifier from the last fetched row. Constraints include Hibernate version differences—na
