v1.2.3

Substreams improvements

• Performance: prevent reprocessing jobs when there is only a mapper in production mode and everything is already cached
• Performance: prevent "UpdateStats" from running too often and stalling other operations when running with a high parallel jobs count
• Performance: fixed bug in scheduler ramp-up function sometimes waiting before raising the number of workers
• Added the output module's hash to the "incoming request" log

Reader node

• The reader-node-bootstrap-url gained the ability to be bootstrapped from a bash script.

  If the bootstrap URL is of the form bash:///<path/to/script>?<parameters>, the bash script at
  <path/to/script> will be executed. The script is going to receive in environment variables the resolved
  reader node variables in the form of READER_NODE_<VARIABLE_NAME>. The fully resolved node arguments
  (from reader-node-arguments) are passed as args to the bash script. The query parameters accepted are:

  • arg=<value> | Pass as extra argument to the script, prepended to the list of resolved node arguments
  • env=<key>%3d<value> | Pass as extra environment variable as <key>=<value> with key being upper-cased (multiple(s) allowed)
  • env_<key>=<value> | Pass as extra environment variable as <key>=<value> with key being upper-cased (multiple(s) allowed)
  • cwd=<path> | Change the working directory to <path> before running the script
  • interpreter=<path> | Use <path> as the interpreter to run the script
  • interpreter_arg=<arg> | Pass <interpreter_arg> as arguments to the interpreter before the script path (multiple(s) allowed)

  [!NOTE]
  The bash:/// script support is currently experimental and might change in upcoming releases, the behavior changes will be
  clearly documented here.

• The reader-node-bootstrap-url gained the ability to be bootstrapped from a pre-made archive file ending with tar.zst or tar.zstd.

• The reader-node-bootstrap-data-url is now added automatically if firecore.Chain#ReaderNodeBootstrapperFactory is non-nil.

  If the bootstrap URL ends with tar.zst or tar.zstd, the archive is read and extracted into the
  reader-node-data-dir location. The archive is expected to contain the full content of the 'reader-node-data-dir'
  and is expanded as is.
