Robert Fratto	2e418b13fd	chore(engine): unexport subpackages (#19384) ... This moves packages around to reduce the surface area of the public engine API: * `pkg/engine/planner` moves to `pkg/engine/internal/planner` * `pkg/engine/executor` moves to `pkg/engine/internal/executor` These packages were only used from `pkg/engine` and did not need to be public. We may make them public again in the future if we want to expose subcomponents of the engine. This move means that `pkg/engine/planner/internal/tree` became `pkg/engine/internal/planner/internal/tree`. To reduce the import path, I also moved that package to `pkg/engine/internal/util/tree`. Other than moving files and updating import paths, no code changes are made. Signed-off-by: Robert Fratto <robertfratto@gmail.com>	3 months ago
Christian Haudum	65de5f95db	chore(engine): Simplify `Pipeline` interface (#19110) ... This PR replaces the two calls to retrieve a value from the pipeline with a single one. To do this, the `Read()` method now returns two arguments: `arrow.Record` and `error`, rather than just the error. If the error is not `nil`, the first argument (arrow.Record) must be ignored by the caller. The `Value()` method is not needed any more and was removed.

Christian Haudum	cea56469b9	chore(engine): Pass context to Pipeline's Read() function (#18459) ... This change unifies how the request context is passed through the execution of pipelines. Instead of storing the context on pipelines, pass them as argument to the `Read()` function. This change alters the interface method of `Pipeline` from `Read() bool` to `Read(context.Context) bool`.

Christian Haudum	6b4430afd0	chore(engine): Collect pipeline records into Loki result (#17447) ... This PR adds the missing piece between existing HTTP handler and the new execution engine, which converts the Apache Arrow records from the vectorized, columnar, pull-based iterator pipeline into the existing (row-based) Loki response format. Since the engine only supports logs queries at the moment, the transformation logic does not take possible metric query results into account.
