| -Spring Data MongoDB 3.x requires the MongoDB Java Driver 4.x. + |
5 |
| -The 4.0 MongoDB Java Driver does no longer support certain features that have already been deprecated in one of the last minor versions. |
6 |
| -Some of the changes affect the initial setup configuration as well as compile/runtime features. |
7 |
| -We summarized the most typical changes one might encounter. |

| -Things to keep in mind when using the 4.0 driver: |
| 6 | +[[upgrading.3-4]] |
| 7 | +== Upgrading MongoDB Drivers |
10 | 8 |
|
11 |
| -* `IndexOperations.resetIndexCache()` is no longer supported. |
12 |
| -* Any `MapReduceOptions.extraOption` is silently ignored. |
13 |
| -* `WriteResult` no longer holds error information but, instead, throws an `Exception`. |
14 |
| -* `MongoOperations.executeInSession(…)` no longer calls `requestStart` and `requestDone`. |
15 |
| -* Index name generation has become a driver-internal operation. |
16 |
| -Spring Data MongoDB still uses the 2.x schema to generate names. |
17 |
| -* Some `Exception` messages differ between the generation 2 and 3 servers as well as between the MMap.v1 and WiredTiger storage engines. |
18 |
| - |
19 |
| -== Dependency Changes |
20 |
| - |
21 |
| -Instead of the single artifact uber-jar `mongo-java-driver`, imports are now split to include separate artifacts: |
22 |
| - |
23 |
| -* `org.mongodb:mongodb-driver-core` (required) |
24 |
| -* `org.mongodb:mongodb-driver-sync` (optional) |
25 |
| -* `org.mongodb:mongodb-driver-reactivestreams` (optional) |
26 |
| - |
27 |
| -Depending on the application one of the `mongodb-driver-sync`, `mongodb-driver-reactivestreams` artifacts is is required next to the mandatory `mongodb-driver-core`. |
28 |
| -It is possible to combine the sync and reactive drivers in one application if needed. |

| -=== Deferred MongoDatabase lookup in `ReactiveMongoDatabaseFactory` |
228 |
| - |
229 |
| -`ReactiveMongoDatabaseFactory` now returns `Mono<MongoDatabase>` instead of `MongoDatabase` to allow access to the Reactor Subscriber context to enable context-specific routing functionality. |
230 |
| - |
231 |
| -This change affects `ReactiveMongoTemplate.getMongoDatabase()` and `ReactiveMongoTemplate.getCollection()` so both methods must follow deferred retrieval. |
