Guides

Describes the execution context, query/update, native aggregation, transaction, Atlas Search, and Vector Search of Reactive Mongo DSL 1.0.0 by feature.

Thematic guides

Execution Context & Resolver

Configures MongoExecutionContext, DriverMongoExecutionContext, collection naming, and key routing.

Spring Integration

Connects the converter, collection naming, and reactive auditing of ReactiveMongoTemplate with an adapter.

Query Flow

Distinguishes different entry flows for general query, native aggregation, Search, and Vector.

FieldsPair & Criteria

Uses conditions, id alias, logical grouping, and driverFilter.

Paging & Sorting

Distinguishes find paging, aggregation paging, PageStream, and SortSpec.

Grouping

Constructs group keys and accumulators and returns the result as a Map.

$lookup

Covers simple joins and let/pipeline-based lookups, count/exists combinations.

Atomic Update

Distinguishes first/multi/upsertOne and document/pipeline updates.

Bulk & History

Covers bulk insert/upsert, entity delete backup, and history snapshots.

Transactions

Describes ClientSession-based getTxJob and session scope, Spring transaction boundaries.

Native Aggregation

Directly executes Driver Bson stages from the first step and uses new Driver features like `$score/$scoreFusion`.

Preview & Explain

Distinguishes between pre-execution pipeline checks and actual MongoDB execution plans.

Atlas Search

Configures search operator, score, highlight, sequence token, and count paths.

Vector Search

Configures manual/Automated Embedding, ANN/ENN, pre/post filters, and nested vector options.

Uses Driver-native features together.

DSL is not a substitute for the MongoDB Driver. For features without dedicated convenience APIs, prioritize using paths that pass through Bson, Driver typed operators, driverOptions(...), and publisher customizers.
