Backend Changes

⛔ Breaking Changes

• Create ES index templates instead of indices (#1627, @pavolloffay)

  This can break existing Elasticsearch deployments if security policies are applied. For instance Jaeger X-Pack configuration now requires permission to create index templates - manage_index_templates.

New Features

• Add Elasticsearch version configuration to rollover script (#1769, @pavolloffay)

• Add Elasticsearch version flag (#1753, @pavolloffay)

• Add Elasticsearch 7 support (#1690, @gregoryfranklin)

  The index mappings in Elasticsearch 7 are not backwards compatible with the older versions. Therefore using Elasticsearch 7 with data created with older version would not work. Elasticsearch 6.8 supports 7.x, 6.x, 5.x compatible mappings. The upgrade has to be done first to ES 6.8, then apply data migration or wait until old daily indices are removed (this requires to start Jaeger with --es.version=7 to force using ES 7.x mappings for newly created indices).

  Jaeger by default uses Elasticsearch ping endpoint (/) to derive the version which is used for index mappings selection. The version can be overridden by flag --es.version.
