How commands are resolved - -Main package: - -- `service/resolver` - -Important files: - -- `CommandResolverService.java` -- many `*CommandResolver.java` classes - -Examples: - -- `FindCommandResolver` -- `InsertOneCommandResolver` -- `UpdateOneCommandResolver` -- `CreateCollectionCommandResolver` -- `CreateKeyspaceCommandResolver` -- `CreateIndexCommandResolver` - -### Resolver role - -A resolver maps: - -- **command object** -- plus **schema-aware command context** - -into: - -- **operation** - -### Resolver lookup - -`CommandResolverService` builds a map: - -- key = command class -- value = matching resolver bean - -So the flow is: - -```text -Command class -> matching CommandResolver -> Operation -``` - -### Why this is important - -Resolvers are the bridge between: - -- API grammar -- schema-aware execution plan - -They are where command semantics become executable behavior. - ---- - -## 10. Example: how `find` is resolved - -File: - -- `service/resolver/FindCommandResolver.java` - -### Table path - -For table-backed schema: - -- uses `TableReadDBOperationBuilder` -- resolves: - - paging state - - filters - - sort - - projection - - limits -- builds a table read operation - -### Collection path - -For collection-backed schema: - -- resolves collection filter expression -- interprets options: - - `limit` - - `skip` - - `pageState` - - `includeSimilarity` - - `includeSortVector` -- validates sort clause -- chooses one of several execution modes: - - vector search - - BM25 search - - in-memory sorted read - - unsorted read - -### Important takeaway - -The same API command name can produce different execution strategies depending on: - -- schema type -- sort mode -- vector search usage -- lexical/BM25 usage -- paging constraints - ---- - -## 11. How commands become CQL - -This is the most important internal concept. - -The translation is **not**: - -```text -HTTP resource -> raw CQL string -``` - -It is more like: - -```text -Command -> Resolver -> Operation -> Task builder -> CQL clauses / QueryBuilder / driver query builder -> executable statement -``` - -### Translation layers - -```mermaid -flowchart LR - A[Command] --> B[CommandResolver] - B --> C[Operation] - C --> D[TaskBuilder] - D --> E[CQL clause objects] - E --> F[Driver query builder or custom QueryBuilder] - F --> G[CQL statement + bind values] - G --> H[Driver execution] -``` - ---- - -## 12. Main packages involved in CQL translation - -### `service/operation` - -This package contains executable operations and DB task abstractions. - -Subpackages include: - -- `collections` -- `tables` -- `keyspaces` -- `databases` -- `tasks` -- `query` -- `filters` -- `embeddings` -- `reranking` - -### `service/operation/tables` - -This is one of the most important packages for table-backed execution. - -Key classes include: - -- `TableReadDBTaskBuilder` -- `TableInsertDBTaskBuilder` -- `TableWhereCQLClause` -- `TableProjection` -- `TableOrderByANNCqlClause` -- `TableOrderByClusteringCqlClause` -- `TableOrderByLexicalCqlClause` -- `WhereCQLClauseAnalyzer` - -### `service/cql` - -Utility package for CQL-related helpers. - -### `service/cql/builder` - -Contains custom query builder classes: - -- `QueryBuilder` -- `Query` - -### `service/cqldriver` - -Contains driver integration and execution support. - -Subpackages include: - -- `executor` -- `serializer` -- `override` - ---- - -## 13. Table read path in detail - -A good example is the table-backed `find` path. - -File: - -- `service/resolver/TableReadDBOperationBuilder.java` - -### What it does - -It assembles a read operation by combining: - -- filter resolution -- CQL sort resolution -- in-memory sort fallback -- paging state -- projection -- where clause generation -- task grouping -- embedding-aware operation wrapping - -### Main steps - -- create `TableReadDBTaskBuilder` -- resolve order-by clause -- compute effective limit -- resolve in-memory sort if needed -- build projection -- build `TableWhereCQLClause` -- create task group -- create accumulator/page builder -- wrap in embedding-aware operation if needed - -### Why this matters - -This builder is where a high-level read command becomes a concrete DB execution plan. - ---- - -## 14. How SELECT CQL is built - -File: - -- `service/operation/tables/TableReadDBTaskBuilder.java` - -### Responsibilities - -This builder creates a `ReadDBTask` using: - -- select clause -- where clause -- order by clause -- paging state -- row sorter -- projection -- CQL options - -### Important behavior - -It also analyzes the where clause using: - -- `WhereCQLClauseAnalyzer` - -This can decide whether `ALLOW FILTERING` is required. - -### Result - -The output is a DB task that contains enough information to execute a Cassandra read. - ---- - -## 15. How INSERT commands become DB tasks - -File: - -- `service/operation/tables/TableInsertDBTaskBuilder.java` - -### Responsibilities - -For insert operations, the builder: - -- parses JSON documents into named values -- validates document shape and limits -- converts values into writable table rows -- creates one insert task per row/document -- accumulates deferrables and response behavior - -### Important supporting concepts - -- `JsonNamedValueContainerFactory` -- `WriteableTableRowBuilder` -- codec registries -- schema-aware row validation - -### Why this matters - -Insert translation is not just string generation. -It includes: - -- JSON shredding -- schema validation -- type conversion -- row materialization - ---- - -## 16. The custom `QueryBuilder` - -File: - -- `service/cql/builder/QueryBuilder.java` - -This class is a custom builder for some query shapes. - -### It supports - -- `SELECT` -- selected columns -- function calls -- `COUNT` -- similarity functions -- `WHERE` expressions -- `ORDER BY ... ANN OF ?` -- `ORDER BY ... BM25 OF ?` -- `LIMIT` - -### Important details - -It builds: - -- a CQL string -- a list of positional bind values - -### Example capabilities - -- vector ANN search -- BM25 lexical search -- similarity score projection -- nested boolean expressions for filters - -### Simplified example output shape - -```text -SELECT col1, col2 -FROM ks.table -WHERE (a = ? AND b > ?) -ORDER BY $vector ANN OF ? -LIMIT 10 -``` - -with bind values stored separately. - ---- - -## 17. Filter translation - -Main packages: - -- `service/resolver/matcher` -- `service/operation/filters` -- `service/operation/tables` -- `api/model/command/clause/filter` - -### What happens - -Filter JSON from the command is translated into internal filter expressions, then into CQL-compatible clauses. - -### Typical stages - -- parse filter clause into command model -- resolve filter semantics against schema -- build logical expression tree -- convert to `WhereCQLClause` -- analyze whether query is legal / needs warnings / needs `ALLOW FILTERING` - -### Important note - -The system distinguishes between: - -- collection semantics -- table semantics - -Those are not always translated the same way. - ---- - -## 18. Sort translation - -Main packages: - -- `api/model/command/clause/sort` -- `service/resolver/sort` -- `service/operation/tables` - -### Supported sort styles include - -- regular field sort -- vector ANN sort -- BM25 lexical sort -- in-memory sort fallback - -### Important note - -Not every sort can be pushed fully to Cassandra. - -The resolver may choose: - -- CQL-native sort -- ANN/BM25 query form -- in-memory sorting after fetch - ---- - -## 19. Vectorization and embeddings - -Main packages: - -- `service/embedding` -- `service/embedding/operation` -- `service/embedding/gateway` -- `service/embedding/configuration` - -### Where vectorization happens - -In `CommandProcessor`, before resolver execution: - -- `dataVectorizerService.vectorize(commandContext, cmd)` - -### Why this matters - -Commands may contain text that must be converted into vectors before query execution. - -Also, `CollectionResource` may create an `EmbeddingProvider` based on schema vectorize configuration. - -### Practical effect - -A request may become: - -- embedding generation first -- then vector search CQL/operation execution - ---- - -## 20. Error handling model - -### Main behavior - -Errors are generally converted into `CommandResult` rather than surfacing as non-200 HTTP responses. - -This is explicitly documented in the resource classes. - -### Where handled - -- `CommandProcessor.handleProcessingFailure(...)` -- `CommandResult` -- exception factories and exception packages - -### Important note - -This means API consumers must inspect the response body, not only the HTTP status code. - ---- - -## 21. Observability and tracing - -Main packages: - -- `metrics` -- `logging` -- `api/model/command/tracing` - -### Built-in observability includes - -- Micrometer timers -- command feature tags -- tenant tagging -- MDC logging -- request tracing -- command-level structured logs - -### Why contributors should know this - -When adding a new command, you should preserve: - -- metrics tagging -- tracing hooks -- MDC-safe execution -- warning/error propagation - ---- - -## 22.

What contributors must know - -### Must-know design rules - -- **Commands are data objects**, not execution objects. -- **Resolvers own semantic translation** from command to operation. -- **Operations/tasks own execution planning**. -- **CQL generation is distributed**, not centralized in one file. -- **Schema type matters everywhere**: - - collection path - - table path -- **Vector and lexical search are first-class execution modes**. -- **HTTP 200 does not guarantee success**; inspect `CommandResult.errors`. -- **Observability is part of the execution contract**, not optional decoration. - -### Must-know implementation patterns - -- add new commands under `api/model/command/impl` -- register them in the appropriate command interface subtype -- create a matching `*CommandResolver` -- ensure schema-specific behavior is explicit -- use existing task builders and clause builders where possible -- preserve warnings, tracing, and metrics behavior - -### Must-know architectural distinction - -There are effectively two execution styles in the same API: - -- **collection/document-oriented behavior** -- **table-oriented behavior** - -The same endpoint may route to different internal logic depending on schema metadata. - ---- - -## 25. Short summary - -### In one sentence - -The Data API accepts a JSON command over HTTP, deserializes it into a typed command object, resolves it through schema-aware command resolvers into operations and DB tasks, translates those tasks into CQL or driver-built statements, executes them against Cassandra, and returns a structured `CommandResult`. - -### In bullet points - -- endpoints are command POST endpoints under `/v1` -- commands are parsed with Jackson polymorphic wrapper-object deserialization -- `RequestContext` carries tenant/auth/features/request metadata -- resources build `CommandContext` and delegate execution -- `MeteredCommandProcessor` adds metrics and logging -- `CommandProcessor` orchestrates expansion, vectorization, resolution, execution, and recovery -- `CommandResolverService` maps command classes to resolvers -- resolvers build operations -- operations use task builders and CQL clause builders -- table execution heavily relies on `service/operation/tables` -- custom CQL generation exists in `service/cql/builder/QueryBuilder` -- vector and BM25 search are integrated into the execution model -- results are returned as `CommandResult`, often with HTTP 200 even on logical failure - ---- - -## 26.
