 If the caller needs multiple to-many paths or a paged query, be suspicious of a
 plain `fetch(...)` on those paths. `fetchQuery()` is often the safer default.

+### `@OneToOne(mappedBy=...)` is EAGER by default — mark it LAZY
+
+The non-owning side of a `@OneToOne` (the side with `mappedBy`) defaults to
+`FetchType.EAGER` per JPA, same as `@ManyToOne`. Unlike a `@ManyToOne`
+reference (which is FK-only until `.fetch()`'d), Ebean's default select for an
+EAGER `@OneToOne(mappedBy=...)` still adds a `left join` to the target table
+on **every** query for the owning entity — even a plain `findById()` — because
+there is no local FK column to use as a lazy reference; the only way to know
+the associated row exists is to join to it.
+
+If that association is rarely needed (e.g. a rarely-read child/detail table),
+this join executes on every load of the parent, including in hot-path list
+queries, and can dominate query cost as more such associations accumulate.
+
+**Always set `fetch = FetchType.LAZY` on `@OneToOne(mappedBy=...)`
+associations unless the association is genuinely needed on (almost) every
+load:**
+
+```java
+@OneToOne(mappedBy = "device", fetch = FetchType.LAZY)
+private SensorBoard sensorBoard;
+```
+
+This correctly excludes the join from Ebean's default select clause (verified
+for FK-based, non-shared-primary-key `@OneToOne` relationships — the common
+case). Callers that do need the association can still `.fetch("sensorBoard")`
+explicitly on the query bean.
+
+**Caveat:** the exclusion is driven by Ebean's default-select-clause
+mechanism. It is bypassed if the query has already been switched into an
+"all properties" mode by something other than the deploy-time
+`FetchType.LAZY`/`EAGER` metadata (for example, an active AutoTune profile
+that supplies its own tuned property set). Confirm the join is actually gone
+by checking generated SQL (`LoggedSql` in tests, or query logging) after
+making this change — don't assume it's excluded from the annotation alone.
+
+### Agent rule
+
+Default new `@OneToOne(mappedBy=...)` fields to `fetch = FetchType.LAZY`
+unless there's a clear reason the association is needed on every load. This
+is a one-line, low-risk change that avoids an always-on join.

AntoineDuComptoirDesPharmaciesandGitHub	90aff3d9ef	Bugfix/3876 (#3877 ) * Add test for #1852 : cascaded delete order broken by a write from a persist callback A join entity owns the foreign key to the bean its delete cascades to, so the join row has to be deleted first. When a BeanPersistController writes to the database from preDelete, that write flushes the batch from inside the flush that is already running : the outer flush has taken the join rows out of their bean holder, so the inner flush finds only the assets and executes them first, which fails on the foreign key. BatchControl flush [DcoLink:0 d:2, DcoAsset:1 d:2] <- outer flush BatchControl flush [DcoLink:0 d:0, DcoAsset:1 d:2, DcoAudit:2 i:1] <- from preDelete The scenario is fixed as a side effect of `a2f954a60` (#3830, released in 18.3.0) which moved controllerPreDelete() ahead of the cascade. The test pins that down : it fails with a DataIntegrityException on a2f954a60~1 and passes on master. The graph is fetched up front on purpose, a lazy load would flush the batch on its own and hide the ordering. * Add failing test reproducing #1852 : out of order cascaded delete on a self referencing tree The shape reported on the issue in 2019 : a container cascades the delete down a tree of TreeBean, and the deletes are not issued deepest first. On 18.4.0 : delete from dco_tree where id in (?) -- the root, whose children are still there delete from dco_tree where id in (?,?,?) delete from dco_tree where id in (?,?) Referential integrity constraint violation: FK_DCO_TREE_PARENT_ID. This is a different defect from the batch reordering fixed by `a2f954a60` : nothing is batched here, the recursion itself walks the tree in the wrong order. Disabled so it does not break the build, remove the annotation to see the failure. * FIX: a persist done from a BeanPersistController callback flushes the batch mid-execution #3148 stopped a query performed from a callback from flushing the batch that is already executing : BatchControl.executeNow disables flushOnQuery for the duration. A persist done from the same callback is not covered. It reaches BatchControl.executeOrQueue, which flushes, and the statements queued behind the one currently executing are issued early. Saving a parent/child graph in batch while an audit row is written from preInsert issues the children before their parent has an id : insert into dco_link (parent_id, asset_id) values (?,?) NULL not allowed for column "PARENT_ID" Same defect on the delete side, where the join rows are issued after the beans they reference (#1852, #3185) — that path no longer reproduces since `a2f954a60` moved controllerPreDelete() ahead of the cascade, but only preDelete was moved, so preInsert and preUpdate still run inside the flush. Guard executeOrQueue with the same reasoning as the existing flushOnQuery guard : while the batch is executing, queue rather than flush. The statements added meanwhile are picked up by the do/while loop in executeAll(). * FIX: same guard on executeStatementOrBatch, a SqlUpdate from a callback also flushes mid-execution executeStatementOrBatch() flushes on (batchFlushOnMixed && !isBeansEmpty()), and persistedBeans is only cleared once executeAll() returns, so during the batch execution that condition holds and a SqlUpdate run from a BeanPersistController callback re-enters the flush the same way a save does. Reproduced with the same test, the callback running a SqlUpdate instead of a save : insert into dco_link (parent_id, asset_id) values (?,?) NULL not allowed for column "PARENT_ID" The second flush of that method, on pstmtHolder.maxSize() >= batchSize, is left untouched : it can only trigger when the pstmt holder fills up mid-execution and there is no test covering it.	2026-08-17 13:02:25 +12:00

With this change we can have a metrics collection for ebean insight using DELTA mode and have a second collection use CUMULATIVE for reporting to OTEL - for the case of fan-out metrics going to 2 places. This isn't strictly needed when only one collection mode is used. * Metrics - Add Mode with RESET, DELTA and CUMULATIVE Previously we were overloading RESET and DELTA but we really need these to be 2 separate modes for the existing tests and the get(reset) api * Fix test TestNatKeyCacheWithForeignKey with cache stats reset --------- Co-authored-by: robin.bygrave <robin.bygrave@eroad.com>	2026-08-14 18:32:23 +12:00
