Ashwanth	5bf2d00458	chore(scheduler): assign tasks in per-worker loop (#20826)	3 weeks ago
Ivan Kalita	7da73aaa7e	chore(dataobj): optimize bitmap decoder (#20467) ... - Use pkg/memory.Bitmap instead of []Value for pageReader presence bitmap - More efficient decoding for bitmapDecoder - only support 0/1 values (this encoding is used only for presence bitmap).	2 months ago
Robert Fratto	005321ed5a	chore(engine): add hierarchical fair priority queues to v2 engine scheduler (#20405)	2 months ago
Christian Haudum	8b59b944f2	chore(dataobj): Use common base config for indexobj and logsobj builders (#20037) ... Use the same config struct for both the indexobj builder and the logsobj builder, since they are configured identically, only with different default values.	3 months ago
Robert Fratto	e9030beedf	chore(engine): track scheduler load/pressure metrics (#19924)	4 months ago
Robert Fratto	016ee7d39e	chore(engine): serializable physical plans (#19672) ... This adds two new packages, `expressionpb` and `physicalpb`, which are serializable representations of `physical.Expression` and `physical.Plan`, respectively. These packages include utility functions to convert between the protobuf representations and the planner types. A translation layer is used due to the complexity of integrating protobuf throughout the engine, as well as difficulties with finding a clean pattern to construct node types. Once we're able to identify a clean and consistent pattern for interacting with the protobuf types throughout the codebase, the translation layer can be removed in favour of using the protobuf types directly.

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>	4 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>	5 months ago
