• 10629: go: Optimize backups to more often transit existing table files instead of doing a merkle dag walk to push missing chunks.
  There are two code paths for taking a logical backup of a Dolt database. One pushes all the existing table files to the backup destination and then sets it up so that it points at the same root value as the existing database. The other code path does the merkle dag walk to push all the missing chunks to the destination store, starting from the desired root value chunk.
  If the destination store is missing a lot of data, this later path currently requires a lot of bookkeeping to keep track of what has been pushed so far and what still needs to be pushed. This is expensive in memory. It requires walking large portions of the existing database, chunk by chunk, which can be expensive in CPU and in I/O seeks.
  This code change seeks to use the code path which uploads existing table files more often when it is the best choice. In order to do so, the code path is now willing to convert a journal file, which should never be pushed to a remote or a backup, into a table file. It will do this on the fly, and will only upload the resulting table file to the destination. The table file does not become part of the source store, and this code path has no interaction with GC.
  For now, there are some hardcoded heuristics for when to prefer pushing existing table files rather than trying to build the upload chunk-by-chunk. This PR uses existing table files when: the destination store is empty (has a zero root hash value) and there is no existing journal file or the existing journal file is less than 20% of the total repo size and the existing journal file is less than 16GB.

  Changelog

  Sourced from go.opentelemetry.io/otel/sdk's changelog.

  [1.40.0/0.62.0/0.16.0] 2026-02-02

  Added

  • Add AlwaysRecord sampler in go.opentelemetry.io/otel/sdk/trace. (#7724)
  • Add Enabled method to all synchronous instrument interfaces (Float64Counter, Float64UpDownCounter, Float64Histogram, Float64Gauge, Int64Counter, Int64UpDownCounter, Int64Histogram, Int64Gauge,) in go.opentelemetry.io/otel/metric. This stabilizes the synchronous instrument enabled feature, allowing users to check if an instrument will process measurements before performing computationally expensive operations. (#7763)
  • Add go.opentelemetry.io/otel/semconv/v1.39.0 package. The package contains semantic conventions from the v1.39.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.38.0. (#7783, #7789)

  Changed

  • Improve the concurrent performance of HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar by 4x. (#7443)
  • Improve the concurrent performance of FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar. (#7447)
  • Improve performance of concurrent histogram measurements in go.opentelemetry.io/otel/sdk/metric. (#7474)
  • Improve performance of concurrent synchronous gauge measurements in go.opentelemetry.io/otel/sdk/metric. (#7478)
  • Add experimental observability metrics in go.opentelemetry.io/otel/exporters/stdout/stdoutmetric. (#7492)
  • Exporter in go.opentelemetry.io/otel/exporters/prometheus ignores metrics with the scope go.opentelemetry.io/contrib/bridges/prometheus. This prevents scrape failures when the Prometheus exporter is misconfigured to get data from the Prometheus bridge. (#7688)
  • Improve performance of concurrent exponential histogram measurements in go.opentelemetry.io/otel/sdk/metric. (#7702)
  • The rpc.grpc.status_code attribute in the experimental metrics emitted from go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc is replaced with the rpc.response.status_code attribute to align with the semantic conventions. (#7854)
  • The rpc.grpc.status_code attribute in the experimental metrics emitted from go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc is replaced with the rpc.response.status_code attribute to align with the semantic conventions. (#7854)

  Fixed

  • Fix bad log message when key-value pairs are dropped because of key duplication in go.opentelemetry.io/otel/sdk/log. (#7662)
  • Fix DroppedAttributes on Record in go.opentelemetry.io/otel/sdk/log to not count the non-attribute key-value pairs dropped because of key duplication. (#7662)
  • Fix SetAttributes on Record in go.opentelemetry.io/otel/sdk/log to not log that attributes are dropped when they are actually not dropped. (#7662)
  • Fix missing request.GetBody in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp to correctly handle HTTP/2 GOAWAY frame. (#7794)
  • WithHostID detector in go.opentelemetry.io/otel/sdk/resource to use full path for ioreg command on Darwin (macOS). (#7818)

  Deprecated

  • Deprecate go.opentelemetry.io/otel/exporters/zipkin. For more information, see the OTel blog post deprecating the Zipkin exporter. (#7670)

  [1.39.0/0.61.0/0.15.0/0.0.14] 2025-12-05

  Added

  • Greatly reduce the cost of recording metrics in go.opentelemetry.io/otel/sdk/metric using hashing for map keys. (#7175)
  • Add WithInstrumentationAttributeSet option to go.opentelemetry.io/otel/log, go.opentelemetry.io/otel/metric, and go.opentelemetry.io/otel/trace packages. This provides a concurrent-safe and performant alternative to WithInstrumentationAttributes by accepting a pre-constructed attribute.Set. (#7287)
  • Add experimental observability for the Prometheus exporter in go.opentelemetry.io/otel/exporters/prometheus. Check the go.opentelemetry.io/otel/exporters/prometheus/internal/x package documentation for more information. (#7345)
  • Add experimental observability metrics in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc. (#7353)
  • Add temporality selector functions DeltaTemporalitySelector, CumulativeTemporalitySelector, LowMemoryTemporalitySelector to go.opentelemetry.io/otel/sdk/metric. (#7434)
  • Add experimental observability metrics for simple log processor in go.opentelemetry.io/otel/sdk/log. (#7548)
  • Add experimental observability metrics in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#7459)

• 10591: Support staging new tables with dolt add -p
  When using 'dolt add -p' to stage rows from a new table (one that exists in working but not in staging), the workspace table UPDATE mechanism previously failed with 'table not found' because GetTableWriter looked for the table in the staging root where it didn't exist yet.
  This change adds ensureTableExistsInStaging() which:
  1. Checks if the table exists in staging (fast path - no-op)
  2. If not, checks if it exists in working
  3. If yes, creates an empty table in staging with the same schema
  4. Updates the session state to reflect the new staging root
     The table is created empty (not copied with data) because 'dolt add -p' allows partial staging - each row selected by the user will be inserted individually into the staging table via the workspace table UPDATE.
     Also adds unit tests and BATS integration tests for the new functionality.
     Example usage: https://gist.github.com/nullun/e88cb2dab9568c6612c98d415a4a2efd
