• ChunkBatcherConfig
  Defines the different thresholds of the associated ChunkBatcher.
• ChunkBuilder
  Helper to incrementally build a Chunk.
• ChunkComponentIter
  The actual iterator implementation for Chunk::iter_component.
• ChunkComponentIterItem
  The underlying item type for ChunkComponentIter.
• ChunkId
  A unique ID for a crate::Chunk.
• ChunkIndicesIter
• LatestAtQuery

• RowId
  A unique ID for a row’s worth of data within a chunk.
