Trait Implementations§

impl EngineRules for SchemalessRules

fn plan_insert(&self, p: InsertParams) -> Result<Vec<SqlPlan>>

Plan an INSERT. Returns Err if the engine does not support inserts (e.g. timeseries routes to TimeseriesIngest instead).

fn plan_upsert(&self, p: UpsertParams) -> Result<Vec<SqlPlan>>

Plan an UPSERT (insert-or-merge). Returns Err for append-only or columnar engines that don’t support merge semantics.

fn plan_scan(&self, p: ScanParams) -> Result<SqlPlan>

Plan a table scan (SELECT without point-get optimization).

fn plan_point_get(&self, p: PointGetParams) -> Result<SqlPlan>

Plan a point lookup by primary key. Returns Err for engines that don’t support O(1) key lookups (e.g. timeseries).

fn plan_update(&self, p: UpdateParams) -> Result<Vec<SqlPlan>>

Plan an UPDATE. Returns Err for append-only engines.

fn plan_delete(&self, p: DeleteParams) -> Result<Vec<SqlPlan>>

Plan a DELETE (point or bulk).

fn plan_aggregate(&self, p: AggregateParams) -> Result<SqlPlan>

Plan a GROUP BY / aggregate query.
