    • 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
