Sizing and diagnosing a JDBC connection pool: L = λ × W where W is connection hold time rather than query latency, the database-side ceiling, HikariCP timeouts and lifetimes, transaction boundaries and idle-in-transaction, N+1 detection, JDBC batching, and what virtual threads change. Use when choosing maximumPoolSize, when connection-timeout is 0 or 30 s, when threads wait for connections under load, when HTTP or queue calls happen inside @Transactional, when connections die silently behind a…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Connection Pool Sizing ## Purpose Size a database pool from measurement and distinguish insufficient local capacity from database saturation, leaks and long-held connections. Raising `maximumPoolSize` helps only if measured database headroom can absorb the extra concurrent work within the required SLO. ## Workflow Before applying settings, inspect compiler/runtime, resolved HikariCP, Spring Boot, Hibernate and JDBC driver versions, database engine/version, metrics binding and transaction/connection release mode. No single Java baseline is declared for this diagnostic workflow; the SQL examples target PostgreSQL, and virtual-thread APIs require Java 21+. Preserve target versions. Missing workload or capacity evidence requires a measurement plan and conditional recommendation, not an invented size. Start from the requested sizing, diagnosis or review and reuse adequate evidence. Ask only for missing workload, deadline or database-budget inputs that change the decision. A review can retain a sound configuration; it does not require changing pool settings or database access code. First trace the affected endpoint or job to its selected transaction manager/DataSource, physical …

How to install
mdr add robsonkades/agent-skills/connection-pool-sizing@sha256:62e14b0741da3924The line at the top of this page pins the label git:20261016.c769bd8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
