Method Detail

createBucketSplitInfo

public static Optional<BackgroundHiveSplitLoader.BucketSplitInfo> createBucketSplitInfo(Optional<HiveBucketHandle> bucketHandle,
                                                                                        Optional<HiveBucketing.HiveBucketFilter> bucketFilter)

getBucketingVersion

public HiveBucketing.BucketingVersion getBucketingVersion()

getBucketColumns

public List<HiveColumnHandle> getBucketColumns()

getTableBucketCount

public int getTableBucketCount()

getReadBucketCount

public int getReadBucketCount()

isTableBucketEnabled

public boolean isTableBucketEnabled(int tableBucketNumber)

Evaluates whether the provided table bucket number passes the bucket predicate. A bucket predicate can be present in two cases:

• Filter on "$bucket" column. e.g. "$bucket" between 0 and 100
• Single-value equality filter on all bucket columns. e.g. for a table with two bucketing columns, bucketCol1 = 'a' AND bucketCol2 = 123
