Gian Merlino 727b65c7e5 Remove SQL experimental banner and other doc adjustments. (#7591)
* Remove SQL experimental banner and other doc adjustments.

Also,

- Adjust the ToC and other docs a bit so SQL and native queries are
  presented on more equal footing.
- De-emphasize querying historicals and peons directly in the
  native query docs. This is a really niche thing and may have been
  confusing to include prominently in the very first paragraph.
- Remove DataSketches and Kafka indexing service from the experimental
  features ToC. They are not experimental any longer and were there in
  error.

* More notes.

Gian Merlino c648775b5b SQL: Remove "useFallback" feature. (#7567)
This feature allows Calcite's Bindable interpreter to be bolted on
top of Druid queries and table scans. I think it should be removed for
a few reasons:

1. It is not recommended for production anyway, because it generates
unscalable query plans (e.g. it will plan a join into two table scans
and then try to do the entire join in memory on the broker).
2. It doesn't work with Druid-specific SQL functions, like TIME_FLOOR,
REGEXP_EXTRACT, APPROX_COUNT_DISTINCT, etc.
3. It makes the SQL planning code needlessly complicated.

With SQL coming out of experimental status soon, it's a good opportunity
to remove this feature.

Gian Merlino 2470b3279f SQL: Fix docs for STRING_FORMAT. (#7455) 2019-04-11 21:57:28 -07:00
Gian Merlino a517f8ce49 Coordinator: Allow dropping all segments. (#7447)
Removes the coordinator sanity check that prevents it from dropping all
segments. It's useful to get rid of this, since the behavior is
unintuitive for dev/testing clusters where users might regularly want
to drop all their data to get back to a clean slate.

But the sanity check was there for a reason: to prevent a race condition
where the coordinator might drop all segments if it ran before the
first metadata store poll finished. This patch addresses that concern
differently, by allowing methods in MetadataSegmentManager to return
null if a poll has not happened yet, and canceling coordinator runs
in that case.

This patch also makes the "dataSources" reference in
SQLMetadataSegmentManager volatile. I'm not sure why it wasn't volatile
before, but it seems necessary to me: it's not final, and it's dereferenced
from multiple threads without synchronization.

Fix and document concurrency of EventReceiverFirehose and TimedShutoffFirehose; Refine concurrency specification of Firehose (#7038)
#### `EventReceiverFirehoseFactory`
Fixed several concurrency bugs in `EventReceiverFirehoseFactory`:
 - Race condition over putting an entry into `producerSequences` in `checkProducerSequence()`.
 - `Stopwatch` used to measure time across threads, but it's a non-thread-safe class.
 - Use `System.nanoTime()` instead of `System.currentTimeMillis()` because the latter are [not suitable](https://stackoverflow.com/a/351571/648955)  for measuring time intervals.
 - `close()` was not synchronized by could be called from multiple threads concurrently.

Removed unnecessary `readLock` (protecting `hasMore()` and `nextRow()` which are always called from a single thread). Removed unnecessary `volatile` modifiers.

Documented threading model and concurrent control flow of `EventReceiverFirehose` instances.

**Important:** please read the updated Javadoc for `EventReceiverFirehose.addAll()`. It allows events from different requests (batches) to be interleaved in the buffer. Is this OK?

#### `TimedShutoffFirehoseFactory`
- Fixed a race condition that was possible because `close()` that was not properly synchronized.

Documented threading model and concurrent control flow of `TimedShutoffFirehose` instances.

#### `Firehose`

Refined concurrency contract of `Firehose` based on `EventReceiverFirehose` implementation. Importantly, now it states that `close()` doesn't affect `hasMore()` and `nextRow()` and could be called concurrently with them. In other words, specified that `close()` is for "row supply" side rather than "row consume" side. However, I didn't check that other `Firehose` implementatations adhere to this contract.

<hr>

This issue is the result of reviewing `EventReceiverFirehose` and `TimedShutoffFirehose` using [this checklist](https://medium.com/@leventov/code-review-checklist-java-concurrency-49398c326154).

David Glasser a81b1b8c9c index_parallel: support !appendToExisting with no explicit intervals (#7046)
* index_parallel: support !appendToExisting with no explicit intervals

This enables ParallelIndexSupervisorTask to dynamically request locks at runtime
if it is run without explicit intervals in the granularity spec and with
appendToExisting set to false.  Previously, it behaved as if appendToExisting
was set to true, which was undocumented and inconsistent with IndexTask and
Hadoop indexing.

Also, when ParallelIndexSupervisorTask allocates segments in the explicit
interval case, fail if its locks on the interval have been revoked.

Also make a few other additions/clarifications to native ingestion docs.

Fixes #6989.

* Review feedback.

PR description on GitHub updated to match.

lets you specify "constant tags" in the config file which are included with
every event. This is helpful if you are running in an environment where you
cannot configure your datadog-agent with tags like "cluster name" --- eg, a
Kubernetes cluster with a datadog-agent on each node and different Druid
deployments in different namespaces but sharing the same datadog-agent
daemonset.

Also fix the name of an existing boolean getter to start with 'is'.

Broker: Await initialization before finishing startup. (#6742)
* Broker: Await initialization before finishing startup.

In particular, hold off on announcing the service and starting the
HTTP server until the server view and SQL metadata cache are finished
initializing. This closes a window of time where a Broker could return
partial results shortly after startup.

As part of this, some simplification of server-lifecycle service
announcements. This helps ensure that the two different kinds of
announcements we do (legacy and new-style) stay in sync.

Gian Merlino 04e7c7fbdc FilteredRequestLogger: Fix start/stop, invalid delegate behavior. (#6637)
* FilteredRequestLogger: Fix start/stop, invalid delegate behavior.

Fixes two bugs:

1) FilteredRequestLogger did not start/stop the delegate.

2) FilteredRequestLogger would ignore an invalid delegate type, and
instead silently substitute the "noop" logger. This was due to a larger
problem with RequestLoggerProvider setup in general; the fix here is
to remove "defaultImpl" from the RequestLoggerProvider interface, and
instead have JsonConfigurator be responsible for creating the
default implementations. It is stricter about things than the old system
was, and is only willing to make a noop logger if it doesn't see any
request logger configs. Otherwise, it'll raise a provision error.

* Remove unneeded annotations.

Deiwin Sarjas e0d1dc5846 Support DogStatsD style tags in statsd-emitter (#6605)
* Replace StatsD client library

The [Datadog package][1] is a StatsD compatible drop-in replacement for the
client library, but it seems to be [better maintained][2] and has support for
Datadog DogStatsD specific features, which will be made use of in a subsequent
commit.

The `count`, `time`, and `gauge` methods are actually exactly compatible with
the previous library and the modifications shouldn't be required, but EasyMock
seems to have a hard time dealing with the variable arguments added by the
DogStatsD library and causes tests to fail if no arguments are provided for the
last String vararg. Passing an empty array fixes the test failures.

[1]: https://github.com/DataDog/java-dogstatsd-client
[2]: https://github.com/tim-group/java-statsd-client/issues/37#issuecomment-248698856

* Retain dimension key information for StatsD metrics

This doesn't change behavior, but allows separating dimensions from the metric
name in subsequent commits.

There is a possible order change for values from
`dimsBuilder.build().values()`, but from the tests it looks like it doesn't
affect actual behavior and the order of user dimensions is also retained.

* Support DogStatsD style tags in statsd-emitter

Datadog [doesn't support name-encoded dimensions and uses a concept of _tags_
instead.][1] This change allows Datadog users to send the metrics without
having to encode the various dimensions in the metric names. This enables
building graphs and monitors with and without aggregation across various
dimensions from the same data.

As tests in this commit verify, the behavior remains the same for users who
don't enable the `druid.emitter.statsd.dogstatsd` configuration flag.

[1]: https://www.datadoghq.com/blog/the-power-of-tagged-metrics/#tags-decouple-collection-and-reporting

* Disable convertRange behavior for DogStatsD users

DogStatsD, unlike regular StatsD, supports floating-point values, so this
behavior is unnecessary. It would be possible to still support `convertRange`,
even with `dogstatsd` enabled, but that would mean that people using the
default mapping would have some of the gauges unnecessarily converted.

`time` is in milliseconds and doesn't support floating-point values.

Clint Wylie 91a37c692d 'suspend' and 'resume' support for supervisors (kafka indexing service, materialized views) (#6234)
* 'suspend' and 'resume' support for kafka indexing service
changes:
* introduces `SuspendableSupervisorSpec` interface to describe supervisors which support suspend/resume functionality controlled through the `SupervisorManager`, which will gracefully shutdown the supervisor and it's tasks, update it's `SupervisorSpec` with either a suspended or running state, and update with the toggled spec. Spec updates are provided by `SuspendableSupervisorSpec.createSuspendedSpec` and `SuspendableSupervisorSpec.createRunningSpec` respectively.
* `KafkaSupervisorSpec` extends `SuspendableSupervisorSpec` and now supports suspend/resume functionality. The difference in behavior between 'running' and 'suspended' state is whether the supervisor will attempt to ensure that indexing tasks are or are not running respectively. Behavior is identical otherwise.
* `SupervisorResource` now provides `/druid/indexer/v1/supervisor/{id}/suspend` and `/druid/indexer/v1/supervisor/{id}/resume` which are used to suspend/resume suspendable supervisors
* Deprecated `/druid/indexer/v1/supervisor/{id}/shutdown` and moved it's functionality to `/druid/indexer/v1/supervisor/{id}/terminate` since 'shutdown' is ambiguous verbage for something that effectively stops a supervisor forever
* Added ability to get all supervisor specs from `/druid/indexer/v1/supervisor` by supplying the 'full' query parameter `/druid/indexer/v1/supervisor?full` which will return a list of json objects of the form `{"id":<id>, "spec":<SupervisorSpec>}`
* Updated overlord console ui to enable suspend/resume, and changed 'shutdown' to 'terminate'

* move overlord console status to own column in supervisor table so does not look like garbage

* spacing

* padding

* other kind of spacing

* fix rebase fail

* fix more better

* all supervisors now suspendable, updated materialized view supervisor to support suspend, more tests
