Robert Fratto	3c99535b0a	chore(engine): provide worker (#19588) ... The new worker package connects to an instance of a scheduler (#19570) for task assignment and execution. A worker spawns a fixed number of threads, each of which execute one task at a time. Signed-off-by: Robert Fratto <robertfratto@gmail.com>	2 months ago

Ivan Kalita	f46ef0eb7c	chore(engine): Refactor streams result builder to use column-oriented processsing (#19505) ... Change streamsResultBuilder.CollectRecord() from row-by-row to column-by-column iteration. This better aligns with Arrow's columnar memory layout, improving CPU cache locality by reading contiguous memory regions. I also remove IsValid checks given that IsNull checks are present. IsValid seems to be an exact opposite of IsNull (based on this code). The slices and label builders for intermediate rows data are reused between CollectRecord.	3 months ago

Christian Haudum	3c5f759f24	chore(engine): Add compatibility node for parsed columns (#19485) ... The v1 engine has a mechanism to rename labels in case they have the same name but different origin, such as labels, structured metadata, or parsed fields. 1. In case a log line has a structured metadata key with the same name as the label name of the stream, than the metadata key is suffixed with `_extracted`, such as `service_extracted`, if `service` exists in both `labels` and `metadata`. 2. In case a parser creates a parsed field with the same as the label name of the stream, then the parsed key is suffixed with `_extracted` in the same way as case 1. However, if the field name also collides with a structured metadata key, then the extracted structured metadata is replaced with the extracted parsed field. This PR only implements the second case.

Christian Haudum	662e1b93f1	chore(engine): Add `LOGQL_COMPAT` marker to logical plan (#19488) ... The marker operation `LOGQL_COMPAT` indicates that the query is expected to return results that are compatible with the old v1 chunks engine. It is used in the physical planner to add required `ColumnCompat` nodes to the plan that handle columns with colliding names but of different semantic types (label, metadata, parsed).	3 months ago

Christian Haudum	c06eb636e5	chore(engine): Add "compatibility node" to physical plan to adhere with naming of "colliding labels" in v1 engine (#19470) ... ### Summary The v1 engine has a mechanism to rename labels in case they have the same name but different origin, such as labels, structured metadata, or parsed fields. 1. In case a log line has a structured metadata key with the same name as the label name of the stream, than the metadata key is suffixed with `_extracted`, such as `service_extracted`, if `service` exists in both `labels` and `metadata`. 2. In case a parser creates a parsed field with the same as the label name of the stream, then the parsed key is suffixed with `_extracted` in the same way as case 1. However, if the field name also collides with a structured metadata key, then the extracted structured metadata is replaced with the extracted parsed field. This PR only implements the first case. As a follow up PR, the second case needs to be implemented as well. Additionally, the newly introduced "compatibility node" should also be made optional with a feature flag and/or per-request.

Christian Haudum	c280531e05	chore: Fix column name regression (#19468) ... The temporary streamID column from the dataobj scan node caused an error when the expression evaluator tried to parse the FQN, which was not valid any more after the recent change that implemented the semantic naming conventions.

Christian Haudum	d5f15705c2	chore: Fix vector results builder (#19467) ... The recent change that implemented the new semantic column naming in PR #19415 introduced a regression in the vector results builder that caused rows that had a NULL value in any column (also the group by columns) to be discarded.

Christian Haudum	119275aab7	chore(engine): Column naming conventions (#19396) ... In the new engine, we need fully qualified column names, since columns from different sources can have the same name. Right now, the distinction between columns with the same name is implemented using the `Metadata` field on the `arrow.Field`. However, it is quite cumbersome to parse the column type and data type from this generic map. This PR introduces package with naming conventions for columns, defined by name, data type, and column type. So, this information can be encoded into the `Name` field of the `arrow.Field`. The convention is defined as ``` [DATA_TYPE].[COLUMN_TYPE].[COLUMN_NAME] ``` #### Examples: * `utf8.label.service_name` * `timestamp_ns.builtin.timestamp` The column type can easily be converted into a `Scope`, which is defined by an origin and type. The mapping is as follows: ``` ColumnTypeBuiltin -> Scope{Record, Attribute} ColumnTypeMetadata -> Scope{Record, Builtin} ColumnTypeLabel -> Scope{Resource, Attribute} ColumnTypeParsed -> Scope{Generated, Attribute} ColumnTypeGenerated -> Scope{Generated, Builtin} ColumnTypeAmbiguous -> Scope{Unscoped, Attribute} ``` --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	3 months ago
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
