Update History

1.17.0(2026/07/14)

New Features

  • Added OTLP HTTP/protobuf endpoints: /otel/v1/traces, /otel/v1/metrics, and /otel/v1/logs (#81)
  • OTLP requests support query token, X-Token, and Bearer tokens, and use the Kodo queue and disk cache (#81)
  • OTLP requests pass through Kodo status codes, bodies, and required headers (#81)

Improvements

  • Improved Sinker routing for aggregation and tail sampling so a failed group no longer affects other groups (#71)
  • Applied the invalid-token negative cache only to eligible write requests (#77)
  • Reduced aggregation memory usage and improved concurrency stability
  • Improved tail-sampling backlog handling by spilling to disk when the memory queue is full
  • Improved disk-cache stability under exceptional conditions

Bug Fixes

  • Fixed race conditions and capacity issues in the Sinker rule cache (#93)

Observability

  • Added dataway_open_files_by_type and dataway_tcp_connections
  • Added tail-sampling, queue, worker, and disk-spill metrics

1.16.1(2026/07/09)

Bug Fixes

  • /v1/write/rum rejects empty bodies with 400 and dataway.emptyBody; non-empty bodies are forwarded unchanged (#82)
  • A full Kodo queue sends eligible requests to disk cache; DataWay returns 503 if cache is unavailable (#83)
  • DataWay reports "cached" only after a successful write and records cache failure reasons (#83)

1.16.0(2026/07/02)

New Features

  • Added IPv6 and dual-stack deployment support; IP allowlists now support IPv4, IPv6, and CIDR (#79)
  • Added bind_ipv6/DW_BIND_IPV6 and trusted_proxies/DW_TRUSTED_PROXIES settings (#78, #79)

Improvements

  • Removed empty bodies and Content-Type from empty Kodo responses (#78)
  • Returned CORS headers only for requests with Origin and added X-Content-Type-Options: nosniff to forwarded responses (#78)

1.15.0(2026/05/27)

New Features

  • Added a bounded Kodo queue for write, upload, and Firehose requests
  • Enabled the queue by default and added DW_KODO_QUEUE_* settings
  • Cached eligible requests when the queue is full. Returned 503 when cache is unavailable
  • Added a token negative cache with DW_TOKEN_NEGATIVE_CACHE_* settings
  • Set the default cache TTL to 5m and the limit to 1000 tokens

Improvements

  • Added token and payload validation to aggregation
  • Added a background queue, 3 retries, and Content-MD5 to aggregation sends
  • Reused reverse proxies and validated aggregation proxy settings
  • Used the current remote_host during cache replay. The default cleanup interval is now 1s
  • Updated Sinker docs. Non-point-write APIs usually do not need __dataway_api rules in DataKit 2.0.0+

Observability

  • Added Kodo queue metrics: dataway_kodo_queue_wait_seconds, dataway_kodo_queue_depth, dataway_kodo_queue_bytes, dataway_kodo_queue_enqueued_total, dataway_kodo_queue_full_total, dataway_kodo_queue_dispatch_total
  • Added invalid-token negative-cache metrics: dataway_token_negative_cache_added_total, dataway_token_negative_cache_blocked_total
  • Added aggregation and tail-sampling metrics: dataway_http_api_body_size_bytes_total, dataway_http_aggr_point_total, dataway_http_tail_sampling_trace_total, dataway_http_tail_sampling_span_total, dataway_http_tail_sampling_packet_send_total
  • Added disk-cache lock-contention metrics: diskcache_lock_wait_seconds, diskcache_lock_contention_total
  • Fixed the sinked label on latency metrics in Sinker scenarios

1.14.0(2026/04/17)

  • Add session replay image APIs

1.13.0(2026/04/10)

New Features

  • Add aggregate and sampling for sidecar mode dataway (#67)

1.12.3(2026/03/26)

  • Sinker header added v2 format (#68)

1.12.2(2026/03/17)

  • Update DataWay image SSL certificates (#69)

1.12.1(2025/12/25)

  • Fix sinker failed to copy request in version 1.12.0 (#66)

1.12.0(2025/12/19)

New Features

  • Optimized Sinker caching mechanism (#34)

    • The new mechanism uses 16-bytes hash of requests for caching instead of complete request info. It employs dual hashing to minimize hash collisions, with a theoretical collision probability of n/2^128, where n is the number of cached keys
    • Added TTL and capacity mechanism to manage Sinker caching: TTL mechanism cleans inactive entries, while capacity mechanism ensures the number of keys in cache does not exceed specified limits. Both TTL and capacity restrictions further reduce the probability of hash collisions mentioned above
