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	d446d47cf8	chore(engine): Prefetch inputs of SortMerge operator (#18395) ... This PR changes how inputs of the SortMerge operator are consumed. The inputs are wrapped with a `prefetchWrapper` which consumes the next batch (`arrow.Record`) in the background while the current batch is processed by the parent node.

Christian Haudum	4305a6aa61	chore(engine): Make literals simple types (#17733) ... Representing data types as simple types (string, int64, float64) makes them more efficient to cast without conversion. Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	10 months ago
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.
