CouchDB Replicator Compression

Overview

The replicator now supports configurable HTTP compression to reduce bandwidth during replication.

Configuration

[replicator]
; Enable compression (default: true)
compress_requests = true

; Minimum body size to compress in bytes (default: 1024)
compress_min_size = 1024

; Algorithm: gzip (default), deflate
compression_algorithm = gzip

; Accept these encodings in responses
accept_encodings = gzip, deflate

Algorithms

  • gzip (default): Best compatibility, built-in to Erlang
  • deflate: Built-in to Erlang, slightly faster than gzip

Statistics

  • couch_replicator.requests.compressed - Total compressed requests
  • couch_replicator.requests.compressed.{algorithm} - Per-algorithm stats
