Changelog

1.17.0(2026/07/14)

New Features

  • Added OTLP HTTP/protobuf interfaces: /otel/v1/traces, /otel/v1/metrics and /otel/v1/logs (#81)
  • OTLP requests support query token, X-Token and Bearer token, and are integrated with the Kodo queue and disk cache (#81)
  • OTLP requests support transparent transmission of Kodo status codes, body and necessary headers (#81)

Optimizations

  • Optimized Sinker diversion for aggregation and tail sampling, failures in a single group no longer affect other groups (#71)
  • Invalid token negative cache only applies to eligible write requests (#77)
  • Optimized memory usage and concurrency stability for aggregation
  • Optimized tail sampling backlog handling, allowing temporary storage to disk when the memory queue is full
  • Improved stability in disk cache exception scenarios

  • Added metrics for tail sampling, send queue, workers and disk temporary storage

1.16.1(2026/07/09)

Bug Fixes

  • /v1/write/rum rejects empty body and returns 400 with dataway.emptyBody; non-empty body is still forwarded as-is (#82)
  • When the Kodo queue is full, cacheable requests are written to disk; return 503 when cache is unavailable (#83)
  • "Cached" is returned only after a successful write, and the reason for cache failure is better recorded (#83)

1.16.0(2026/07/02)

New Features

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

Optimizations

  • When the Kodo success response is empty, no empty body and Content-Type are returned (#78)
  • CORS headers are returned only for requests with an Origin header, and X-Content-Type-Options: nosniff is added to forwarded responses (#78)

1.15.0(2026/05/27)

New Features

  • Added a bounded Kodo queue covering write, upload and Firehose requests
  • The queue is enabled by default and supports DW_KODO_QUEUE_* environment variables
  • Cacheable requests are cached when the queue is full. Return 503 when cache is unavailable
  • Added invalid token negative cache supporting DW_TOKEN_NEGATIVE_CACHE_* environment variables
  • Default TTL for negative cache is 5m, with a maximum of 1000 tokens

Optimizations

  • Added token and payload validation for aggregation API
  • Aggregation sending uses a background queue with 3 retries and adds Content-MD5
  • Aggregation proxy reuses the reverse proxy and validates related configurations
  • Cache replay uses the current remote_host, default cleanup interval changed to 1s
  • Updated Sinker documentation. From DataKit 2.0.0 onwards, non-point write APIs usually do not require __dataway_api rules

Observability

  • Added Kodo queue related 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/tail sampling related 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 in latency metrics under Sinker scenarios

1.12.1(2025/12/25)

  • Fixed the issue in version 1.12.0 where Sinker diversion could not copy requests (#66)

1.12.0(2025/12/19)

New Features

  • Optimized Sinker cache mechanism (#34)

    • The new Sinker cache mechanism caches based on the hash characteristic (16 bytes) of the request, rather than caching the entire request characteristic. Two-way hashing is used to minimize hash collisions. The theoretical collision probability is n/2^128, where n is the number of cached keys.
    • Added TTL and capacity mechanisms to the Sinker cache to further limit memory usage: the TTL mechanism cleans up inactive caches, and the capacity mechanism ensures the number of cached keys does not exceed the specified limit. TTL and capacity limits further reduce the hash collision probability mentioned above.

  • Added configuration to optimize DataWay HTTP header return, reducing DataWay public network traffic (#65)
