Index Backends

Reconify builds an index for the right source before matching the left source.

memory

index:
  backend: memory

Fastest backend. Use when the right file and index fit comfortably in RAM.

disk

index:
  backend: disk
  spill_dir: "/tmp/reconify"

SQLite-backed temporary index. Lower RAM usage, slower lookups.

If spill_dir is omitted, Reconify uses a system temp directory.

auto

index:
  backend: auto
  auto_max_right_file_mb: 2048

Uses disk when the right file size exceeds the threshold; otherwise uses memory.

When auto_max_right_file_mb is unset or zero, the runtime default threshold is 2048 MB.
