[CARBONDATA-2637][BloomDataMap] Fix bugs for deferred rebuild for bloomfilter datamap Previously when we implement ISSUE-2633, deferred rebuild for bloom datamap is disabled for bloomfilter datamap due to unhandled bugs. In this commit, we fixed the bugs and bring this feature back. Since bloomfilter datamap create index on the carbon native raw bytes, we have to convert original literal value to carbon native bytes both in loading and querying. This closes #2425 Project: http://git-wip-us.apache.org/repos/asf/carbondata/repo Commit: http://git-wip-us.apache.org/repos/asf/carbondata/commit/5c483f3c Tree: http://git-wip-us.apache.org/repos/asf/carbondata/tree/5c483f3c Diff: http://git-wip-us.apache.org/repos/asf/carbondata/diff/5c483f3c Branch: refs/heads/master Commit: 5c483f3ce9fb3e281041a1ec6d5b62295ae8341d Parents: 7a1d12a Author: xuchuanyin <[email protected]> Authored: Sat Jul 7 22:04:39 2018 +0800 Committer: Jacky Li <[email protected]> Committed: Mon Jul 9 17:32:27 2018 +0800 ---------------------------------------------------------------------- .../core/datamap/dev/DataMapBuilder.java | 4 + .../scan/collector/ResultCollectorFactory.java | 4 + .../impl/RowIdRawBasedResultCollector.java | 172 +++++++++++ .../bloom/AbstractBloomDataMapWriter.java | 284 +++++++++++++++++ .../datamap/bloom/BloomDataMapBuilder.java | 33 +- .../datamap/bloom/BloomDataMapWriter.java | 248 +-------------- .../datamap/lucene/LuceneDataMapBuilder.java | 4 + .../testsuite/datamap/TestDataMapStatus.scala | 8 + .../datamap/IndexDataMapRebuildRDD.scala | 152 +++++++-- .../BloomCoarseGrainDataMapFunctionSuite.scala | 305 +++++++++++++++++++ .../bloom/BloomCoarseGrainDataMapSuite.scala | 6 +- 11 files changed, 934 insertions(+), 286 deletions(-) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/carbondata/blob/5c483f3c/core/src/main/java/org/apache/carbondata/core/datamap/dev/DataMapBuilder.java ---------------------------------------------------------------------- diff --git a/core/src/main/java/org/apache/carbondata/core/datamap/dev/DataMapBuilder.java b/core/src/main/java/org/apache/carbondata/core/datamap/dev/DataMapBuilder.java index 570a1ce..c96d4a0 100644 --- a/core/src/main/java/org/apache/carbondata/core/datamap/dev/DataMapBuilder.java +++ b/core/src/main/java/org/apache/carbondata/core/datamap/dev/DataMapBuilder.java @@ -35,4 +35,8 @@ public interface DataMapBuilder { void finish() throws IOException; void close() throws IOException; + /** + * whether create index on internal carbon bytes (such as dictionary encoded) or original value + */ + boolean isIndexForCarbonRawBytes(); } http://git-wip-us.apache.org/repos/asf/carbondata/blob/5c483f3c/core/src/main/java/org/apache/carbondata/core/scan/collector/ResultCollectorFactory.java ---------------------------------------------------------------------- diff --git a/core/src/main/java/org/apache/carbondata/core/scan/collector/ResultCollectorFactory.java b/core/src/main/java/org/apache/carbondata/core/scan/collector/ResultCollectorFactory.java index 0b1dde5..8902fc2 100644 --- a/core/src/main/java/org/apache/carbondata/core/scan/collector/ResultCollectorFactory.java +++ b/core/src/main/java/org/apache/carbondata/core/scan/collector/ResultCollectorFactory.java @@ -26,6 +26,7 @@ import org.apache.carbondata.core.scan.collector.impl.RestructureBasedDictionary import org.apache.carbondata.core.scan.collector.impl.RestructureBasedRawResultCollector; import org.apache.carbondata.core.scan.collector.impl.RestructureBasedVectorResultCollector; import org.apache.carbondata.core.scan.collector.impl.RowIdBasedResultCollector; +import org.apache.carbondata.core.scan.collector.impl.RowIdRawBasedResultCollector; import org.apache.carbondata.core.scan.executor.infos.BlockExecutionInfo; /** @@ -52,6 +53,9 @@ public class ResultCollectorFactory { if (blockExecutionInfo.isRestructuredBlock()) { LOGGER.info("Restructure based raw collector is used to scan and collect the data"); scannerResultAggregator = new RestructureBasedRawResultCollector(blockExecutionInfo); + } else if (blockExecutionInfo.isRequiredRowId()) { + LOGGER.info("RowId based raw collector is used to scan and collect the data"); + scannerResultAggregator = new RowIdRawBasedResultCollector(blockExecutionInfo); } else { LOGGER.info("Row based raw collector is used to scan and collect the data"); scannerResultAggregator = new RawBasedResultCollector(blockExecutionInfo); http://git-wip-us.apache.org/repos/asf/carbondata/blob/5c483f3c/core/src/main/java/org/apache/carbondata/core/scan/collector/impl/RowIdRawBasedResultCollector.java ---------------------------------------------------------------------- diff --git a/core/src/main/java/org/apache/carbondata/core/scan/collector/impl/RowIdRawBasedResultCollector.java b/core/src/main/java/org/apache/carbondata/core/scan/collector/impl/RowIdRawBasedResultCollector.java new file mode 100644 index 0000000..a68265d --- /dev/null +++ b/core/src/main/java/org/apache/carbondata/core/scan/collector/impl/RowIdRawBasedResultCollector.java @@ -0,0 +1,172 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
