BloomIndexConfig

case class BloomIndexConfig(column: String, fpr: Double = 0.01) extends Product with Serializable

Configuration for a bloom filter index.

Bloom filters are probabilistic data structures that provide:

  • Guaranteed NO false negatives (if filter says "no", value definitely absent)
  • Configurable false positive rate (if filter says "yes", value MIGHT be present)
  • Space-efficient storage (approximately 10 bits per element at 1% FPR)
column

The column name to create a bloom filter for

fpr

False positive rate (0.0 to 1.0, default 0.01 = 1%)
