PR Checklist

PR Structure

  • This PR has reasonably narrow scope (if not, break it down into smaller PRs).
  • This PR avoids mixing refactoring changes with feature changes (split into two PRs
    otherwise).
  • This PR's title starts with name of package that is most changed in the PR, ex.
    services/friendbot, or all or doc if the changes are broad or impact many
    packages.

Thoroughness

  • This PR adds tests for the most critical parts of the new functionality or fixes.
  • I've updated any docs (developer docs, .md
    files, etc... affected by this change). Take a look in the docs folder for a given service,
    like this one.

Release planning

  • I've reviewed the changes in this PR and if I consider them worthwhile for being mentioned on release notes then I have updated the relevant CHANGELOG.md within the component folder structure. For example, if I changed horizon, then I updated (services/horizon/CHANGELOG.md. I add a new line item describing the change and reference to this PR. If I don't update a CHANGELOG, I acknowledge this PR's change may not be mentioned in future release notes.
  • I've decided if this PR requires a new major/minor version according to
    semver, or if it's mainly a patch change. The PR is targeted at the next
    release branch if it's not a patch change.

What

Added new PublishFromBufferedStorageBackend to provide a functional origin for streaming data development as part of CDP processors library.

Why

Provide efficient tooling in the sdk to produce a stream of tx-meta from a remote Datastore that has pre-computed tx-meta files from Galexie. The stream is established as a callback function which caller passes, it will be asynchronously invoked and serves as origin in a data transformation pipeline, providing source of network tx-meta to which pipeline transform operators can derive from.

Closes: #5412
