Full Changelog: 0.5.0...0.5.1

0.5.0

What's Changed

CHANGES

• Accept invoking the program without default configuration file config.yml
  In this case, the program will fall back to the builtin defaults, essentially
  connecting to localhost:5432 with username crate.
• Add query timeouts using context cancellation. The corresponding
  configuration settings are read_timeout and write_timeout.
• Use a different connection pool for read vs. write operations.
  The corresponding settings to configure the maximum pool sizes
  are read_pool_size_max and write_pool_size_max.
• Accept invocation without default configuration file config.yml.
• Add command line option -config.make to print a blueprint configuration
  file to stdout.
• Use a DSN-style connection string for talking to pgx5.
• Add program version to startup log message.

DEPENDENCIES

• Add support for Go 1.20 and 1.21, drop support for previous releases
• Update dependency packages across the board to their latest or minor patch releases
• Update Prometheus libraries (client: 1.18, server: 2.48)
• Update Protocol Buffers libraries (google.golang.org/protobuf 1.31)
• Update to pgx5 library

BREAKING CHANGES

• This release removes the default value for the -config.file command line
  option, which was config.yml. When the option is omitted, the service
  will use the built-in settings, connecting to CrateDB on localhost:5432.

Full Changelog: 0.4.0...0.5.0

0.4.0

BREAKING CHANGES

• This release changes the toplevel configuration section name to cratedb_endpoints.
  It is an aftermath of the "naming things" refactorings happening in 0.3.0.

CHANGES

• Improve network behaviour: Adjust TCP timeout and keepalive settings to
  mitigate problems that can occur when the adapter in connecting to CrateDB
  via a load balancer that may drop idle connections in-transparently, such as
  in AKS. The default values are:

  • KeepAlive: 30 seconds
  • ConnectTimeout: 10 seconds

  The TCP connect timeout can be adjusted by using the -tcp.connect.timeout
  option.

0.3.0

BREAKING CHANGES

• This release changes the program name to cratedb-prometheus-adapter
  and the default prefix for exported metrics to cratedb_prometheus_adapter_.
  The latter can be reconfigured using the new -metrics.export.prefix option.

CHANGES

• Provide a default config.yml in the Docker image, which can be replaced
  by mounting a file on /etc/cratedb-prometheus-adapter/config.yml.

• Made Go 1.16 a minimum requirement.

• Updated project to make use of Go modules <https://golang.org/ref/mod>_
  instead of Govendor.

• Renamed the program to cratedb-prometheus-adapter.

• Renamed the exported metric prefix to cratedb_prometheus_adapter_. It is
  now, for example, cratedb_prometheus_adapter_write_latency_seconds.
  Attention: This is a breaking change with respect to your exported metric
  names. In order to keep the former name, use
  ./cratedb-prometheus-adapter -metrics.export.prefix=crate_adapter_.

0.2.1

• Fixed the translation of prometheus queries using regular expressions
  (metric_name{job=~"something"}) , so that the generated SQL queries match
  the proper records in CrateDB.

• Fixed an issue that caused reads to increment the write metrics instead of
  the read metrics.
