Various documentation updates. (#13107)
* Various documentation updates.

1) Split out "data management" from "ingestion". Break it into thematic pages.

2) Move "SQL-based ingestion" into the Ingestion category. Adjust content so
   all conceptual content is in concepts.md and all syntax content is in reference.md.
   Shorten the known issues page to the most interesting ones.

3) Add SQL-based ingestion to the ingestion method comparison page. Remove the
   index task, since index_parallel is just as good when maxNumConcurrentSubTasks: 1.

4) Rename various mentions of "Druid console" to "web console".

5) Add additional information to ingestion/partitioning.md.

6) Remove a mention of Tranquility.

7) Remove a note about upgrading to Druid 0.10.1.

8) Remove no-longer-relevant task types from ingestion/tasks.md.

9) Move ingestion/native-batch-firehose.md to the hidden section. It was previously deprecated.

10) Move ingestion/native-batch-simple-task.md to the hidden section. It is still linked in some
    places, but it isn't very useful compared to index_parallel, so it shouldn't take up space
    in the sidebar.

11) Make all br tags self-closing.

12) Certain other cosmetic changes.

13) Update to node-sass 7.

* make travis use node12 for docs

Enable conversion of join to filter by default (#12868) 2022-08-13 20:37:43 +05:30
Gian Merlino 01d555e47b
Adjust "in" filter null behavior to match "selector". (#12863)
* Adjust "in" filter null behavior to match "selector".

Now, both of them match numeric nulls if constructed with a "null" value.

This is consistent as far as native execution goes, but doesn't match
the behavior of SQL = and IN. So, to address that, this patch also
updates the docs to clarify that the native filters do match nulls.

This patch also updates the SQL docs to describe how Boolean logic is
handled in addition to how NULL values are handled.

Fixes #12856.

* Fix test.

Automatic sizing for GroupBy dictionaries. (#12763)
* Automatic sizing for GroupBy dictionary sizes.

Merging and selector dictionary sizes currently both default to 100MB.
This is not optimal, because it can lead to OOM on small servers and
insufficient resource utilization on larger servers. It also invites
end users to try to tune it when queries run out of dictionary space,
which can make things worse if the end user sets it to too high.

So, this patch:

- Adds automatic tuning for selector and merge dictionaries. Selectors
  use up to 15% of the heap and merge buffers use up to 30% of the heap
  (aggregate across all queries).

- Updates out-of-memory error messages to emphasize enabling disk
  spilling vs. increasing memory parameters. With the memory parameters
  automatically sized, it is more likely that an end user will get
  benefit from enabling disk spilling.

- Removes the query context parameters that allow lowering of configured
  dictionary sizes. These complicate the calculation, and I don't see a
  reasonable use case for them.

* Adjust tests.

* Review adjustments.

* Additional comment.

* Remove unused import.

ConcurrentGrouper: Add mergeThreadLocal option, fix bug around the switch to spilling. (#12513)
* ConcurrentGrouper: Add option to always slice up merge buffers thread-locally.

Normally, the ConcurrentGrouper shares merge buffers across processing
threads until spilling starts, and then switches to a thread-local model.
This minimizes memory use and reduces likelihood of spilling, which is
good, but it creates thread contention. The new mergeThreadLocal option
causes a query to start in thread-local mode immediately, and allows us
to experiment with the relative performance of the two modes.

* Fix grammar in docs.

* Fix race in ConcurrentGrouper.

* Fix issue with timeouts.

* Remove unused import.

* Add "tradeoff" to dictionary.

SQL: Add is_active to sys.segments, update examples and docs. (#11550)
* SQL: Add is_active to sys.segments, update examples and docs.

is_active is short for:

  (is_published = 1 AND is_overshadowed = 0) OR is_realtime = 1

It's important because this represents "all the segments that should
be queryable, whether or not they actually are right now". Most of the
time, this is the set of segments that people will want to look at.

The web console already adds this filter to a lot of its queries,
proving its usefulness.

This patch also reworks the caveat at the bottom of the sys.segments
section, so its information is mixed into the description of each result
field. This should make it more likely for people to see the information.

* Wording updates.

* Adjustments for spellcheck.

* Adjust IT.

Enable vectorized virtual column processing by default. (#12520)
In the majority of cases, this improves performance.

There's only one case I'm aware of where this may be a net negative: for time_floor(__time, <period>) where there are many repeated __time values. In nonvectorized processing, SingleLongInputCachingExpressionColumnValueSelector implements an optimization to avoid computing the time_floor function on every row. There is no such optimization in vectorized processing.

IMO, we shouldn't mention this in the docs. Rationale: It's too fiddly of a thing: it's not guaranteed that nonvectorized processing will be faster due to the optimization, because it would have to overcome the inherent speed advantage of vectorization. So it'd always require testing to determine the best setting for a specific dataset. It would be bad if users disabled vectorization thinking it would speed up their queries, and it actually slowed them down. And even if users do their own testing, at some point in the future we'll implement the optimization for vectorized processing too, and it's likely that users that explicitly disabled vectorization will continue to have it disabled. I'd like to avoid this outcome by encouraging all users to enable vectorization at all times. Really advanced users would be following development activity anyway, and can read this issue

Reduce allocations due to Jackson serialization. (#12468)
* Reduce allocations due to Jackson serialization.

This patch attacks two sources of allocations during Jackson
serialization:

1) ObjectMapper.writeValue and JsonGenerator.writeObject create a new
   DefaultSerializerProvider instance for each call. It has lots of
   fields and creates pressure on the garbage collector. So, this patch
   adds helper functions in JacksonUtils that enable reuse of
   SerializerProvider objects and updates various call sites to make
   use of this.

2) GroupByQueryToolChest copies the ObjectMapper for every query to
   install a special module that supports backwards compatibility with
   map-based rows. This isn't needed if resultAsArray is set and
   all servers are running Druid 0.16.0 or later. This release was a
   while ago. So, this patch disables backwards compatibility by default,
   which eliminates the need to copy the heavyweight ObjectMapper. The
   patch also introduces a configuration option that allows admins to
   explicitly enable backwards compatibility.

* Add test.

* Update additional call sites and add to forbidden APIs.

GroupBy: Cap dictionary-building selector memory usage. (#12309)
* GroupBy: Cap dictionary-building selector memory usage.

New context parameter "maxSelectorDictionarySize" controls when the
per-segment processing code should return early and trigger a trip
to the merge buffer.

Includes:

- Vectorized and nonvectorized implementations.
- Adjustments to GroupByQueryRunnerTest to exercise this code in
  the v2SmallDictionary suite. (Both the selector dictionary and
  the merging dictionary will be small in that suite.)
- Tests for the new config parameter.

* Fix issues from tests.

* Add "pre-existing" to dictionary.

* Simplify GroupByColumnSelectorStrategy interface by removing one of the writeToKeyBuffer methods.

* Adjustments from review comments.

Adding new config for disabling group by on multiValue column (#12253)
As part of #12078 one of the followup's was to have a specific config which does not allow accidental unnesting of multi value columns if such columns become part of the grouping key.
Added a config groupByEnableMultiValueUnnesting which can be set in the query context.

The default value of groupByEnableMultiValueUnnesting is true, therefore it does not change the current engine behavior.
If groupByEnableMultiValueUnnesting is set to false, the query will fail if it encounters a multi-value column in the grouping key.

Specify time column for first/last aggregators (#11949)
Add the ability to pass time column in first/last aggregator (and latest/earliest SQL functions). It is to support cases where the time to query upon is stored as a part of a column different than __time. Also, some other logical time column can be specified.
