Gian Merlino 97ddb38d75 DatasourceInputSplit: Serialize with write instead of writeUTF. (#4195)
writeUTF has a limit of 64KB, making it difficult to write out splits
that read a large number of descriptors for small segments.

Gian Merlino b4289c0004 Remove "granularity" from IngestSegmentFirehose. (#4110)
It wasn't doing anything useful (the sequences were being concatted, and
cursor.getTime() wasn't being called) and it defaulted to Granularities.NONE.
Changing it to Granularities.ALL gave me a 700x+ performance boost on a
small dataset I was reindexing (2m27s to 365ms). Most of that was from avoiding
making a lot of unnecessary column selectors.

* Add virtual column types, holder serde, and safety features.

Virtual columns:
- add long, float, dimension selectors
- put cache IDs in VirtualColumnCacheHelper
- adjust serde so VirtualColumns can be the holder object for Jackson
- add fail-fast validation for cycle detection and duplicates
- add expression virtual column in core

Storage adapters:
- move virtual column hooks before checking base columns, to prevent surprises
  when a new base column is added that happens to have the same name as a
  virtual column.

* Fix ExtractionDimensionSpecs with virtual dimensions.

* Fix unused imports.

* CR comments

- Added specializations for time-based vs non-time-based DimensionSelector in RBCSF.
- Added convenience method DimensionHanderUtils.createColumnSelectorPlus.
- Added singleton ZeroIndexedInts.
- Added test cases for DimFilterHavingSpec.

* Make ValueMatcherColumnSelectorStrategy actually use the associated selector.

* Add RangeIndexedInts.

* DimFilterHavingSpec: Fix concurrent usage guard on jdk7.

* Add assertion to ZeroIndexedInts.

* Rename no-longer-volatile members.

Erik Dubbelboer c0c34f82ad Fix reindexing of segments in Google Cloud Storage (#3788)
Google Cloud Storage allows `:` in paths. For this reason `google` was
not added to da007ca3c2/indexing-hadoop/src/main/java/io/druid/indexer/JobHelper.java (L585)
Normally this is not an issue but when reindexing segments the Hadoop
code for `getSplits` trips up on the `:` and returns:
`Relative path in absolute URI`
This patch URL encodes the `:` character making it work in Hadoop as
well.

praveev 52a74cf84f Use timestamp in millis as Map key instead of DateTime object (#3674)
* Use Long timestamp as key instead of DateTime.

DateTime representation is screwed up when you store with an obj
and read with a different DateTime obj.

For example: The code below fails when you use DateTime as key
```
        DateTime odt = DateTime.now(DateTimeUtils.getZone(DateTimeZone.forID("America/Los_Angeles")));
        HashMap<DateTime, String> map = new HashMap<>();
        map.put(odt, "abc");
        DateTime dt = new DateTime(odt.getMillis());
        System.out.println(map.get(dt));
```

Björn Zettergren 2462c82c0e New defaults for maxRowsInMemory rowFlushBoundary
To bring consistency to docs and source this commit changes the default
values for maxRowsInMemory and rowFlushBoundary to 75000 after
discussion in PR https://github.com/druid-io/druid/pull/2457.

The previous default was 500000 and it's lower now on the grounds that
it's better for a default to be somewhat less efficient, and work,
than to reach for the stars and possibly result in
"OutOfMemoryError: java heap space" errors.
2016-03-01 13:50:28 +01:00
Gian Merlino 3534483433 Better handling of ParseExceptions.
Two changes:
- Allow IncrementalIndex to suppress ParseExceptions on "aggregate".
- Add "reportParseExceptions" option to realtime tuning configs. By default this is "false".

Behavior of the counters should now be:

- processed: Number of rows indexed, including rows where some fields could be parsed and some could not.
- thrownAway: Number of rows thrown away due to rejection policy.
- unparseable: Number of rows thrown away due to being completely unparseable (no fields salvageable at all).

If "reportParseExceptions" is true then "unparseable" will always be zero (because a parse error would
cause an exception to be thrown). In addition, "processed" will only include fully parseable rows
(because even partial parse failures will cause exceptions to be thrown).

Fixes #2510.

2015-11-18 21:05:46 -08:00
Gian Merlino e4e5f0375b SegmentAllocateAction (fixes #1515)
This is a feature meant to allow realtime tasks to work without being told upfront
what shardSpec they should use (so we can potentially publish a variable number
of segments per interval).

The idea is that there is a "pendingSegments" table in the metadata store that
tracks allocated segments. Each one has a segment id (the same segment id we know
and love) and is also part of a sequence.

The sequences are an idea from @cheddar that offers a way of doing replication.
If there are N tasks reading exactly the same data with exactly the same logic
(think Kafka tasks reading a fixed range of offsets) then you can place them
in the same sequence, and they will generate the same sequence of segments.

Michael Schiff 6ad451a44a JobHelper.ensurePaths will set job properties from config (tuningConfig.jobProperties) before adding input paths to the config.
Adding input paths will create Path and FileSystem instances which may depend on the values in the job config.
This allows all properties to be set from the spec file, avoiding having to directly edit cluster xml files.

IndexGeneratorJob.run adds job properties before adding input paths (adding input paths may depend on having job properies set)

JobHelperTest confirms that JobHelper.ensurePaths adds job properties
