(2) The upper limit of Compaction Level Threshold is 100, which is too small to meet the scenario with massive small files (3) There is a bug to limit alter table in windows env. Modification content: (1) AlterTableUtil support alter Compaction_Level_Threshold (2) CarbonProperties increases the upper limit of Compaction_Level_Threshold to 10000 from 100. (3) Fix the bug which limit alter table in windows env This closes #3553 --- .../core/constants/CarbonCommonConstants.java | 11 ++++ .../carbondata/core/util/CarbonProperties.java | 9 ++- .../carbondata/core/util/path/CarbonTablePath.java | 4 +- .../TestAlterTableCompactionLevelThreshold.scala | 70 ++++++++++++++++++++++ .../org/apache/spark/util/AlterTableUtil.scala | 23 ++++++- 5 files changed, 114 insertions(+), 3 deletions(-) diff --git a/core/src/main/java/org/apache/carbondata/core/constants/CarbonCommonConstants.java b/core/src/main/java/org/apache/carbondata/core/constants/CarbonCommonConstants.java index 8c7d7c4..22ec7cf 100644 --- a/core/src/main/java/org/apache/carbondata/core/constants/CarbonCommonConstants.java +++ b/core/src/main/java/org/apache/carbondata/core/constants/CarbonCommonConstants.java @@ -842,6 +842,17 @@ public final class CarbonCommonConstants { */ public static final String DEFAULT_SEGMENT_LEVEL_THRESHOLD = "4,3"; + + /** + * Lower limit for the number of segment compacted per time + */ + public static final int NUMBER_OF_SEGMENT_COMPACTED_PERTIME_LOWER_LIMIT = 0; + + /** + * Upper limit for the number of segment compacted per time + */ + public static final int NUMBER_OF_SEGMENT_COMPACTED_PERTIME_UPPER_LIMIT = 10000; + /** * Number of Update Delta files which is the Threshold for IUD compaction. * Only accepted Range is 0 - 10000.
