jaeger v1.10.0 Release Notes

Release Date: 2019-02-15 // about 5 years ago

  • Backend Changes

    💥 Breaking Changes

    Migration Path:

    1. Run plugin/storage/cassandra/schema/migration/v001tov002part1.sh which will copy dependencies into a csv, update the dependency UDT, create a new dependencies_v2 table, and write dependencies from the csv into the dependencies_v2 table.
    2. Run the collector and query services with the cassandra flag cassandra.enable-dependencies-v2=true which will instruct jaeger to write and read to and from the new dependencies_v2 table. ⚡️ 3. Update spark job to write to the new dependencies_v2 table. The feature will be done in #58. 🔌 4. Run plugin/storage/cassandra/schema/migration/v001tov002part2.sh which will DELETE the old dependency table and the SASI index.

    🚚 Users who wish to continue to use the v1 table don't have to do anything as the cassandra flag cassandra.enable-dependencies-v2 will default to false. Users may migrate on their own timeline however new features will be built solely on the dependencies_v2 table. In the future, we will remove support for v1 completely.
