Migration from 0.70 to 0.7.1

Quickwit 0.7.1 will create the new index otel-logs-v0_7 which is now used by default when ingesting data with the OTEL gRPC and HTTP API.

In the traces index otel-traces-v0_7, the service_name field is now fast. No migration is done if otel-traces-v0_7 already exists. If you want service_name field to be fast, you have to delete first the existing otel-traces-v0_7 index or you need to create your own index.

Beta release of Quicwkit Lambdas.

Migration from 0.6.x to 0.7

The format of the index and internal objects stored in the metastore of 0.7 is backward compatible with 0.6.

If you are using the OTEL indexes and ingesting data into indexes the otel-logs-v0_6 and otel-traces-v0_6, you must stop indexing before upgrading.
Indeed, the first time you start Quickwit 0.7, it will update the doc mapping fields of Trace ID and Span ID of those two indexes by changing their input/output formats from base64 to hex. This is automatic: you don't have to perform any manual operation.
Quickwit 0.7 will create new indexes otel-logs-v0_7 and otel-traces-v0_7, which are now used by default when ingesting data with the OTEL gRPC and HTTP API. The Jaeger gRPC and HTTP APIs will query both otel-traces-v0_6 and otel-traces-v0_7 by default.
It's possible to define the index ID you want to use for OTEL gRPC endpoints and Jaeger gRPC API by setting the request header qw-otel-logs-index or qw-otel-traces-index to the index ID you want to target.

Fixed

• Increase the gRPC payload limits of the metastore gRPC client to 20MiB in commit f76fcee to fix #4256. It only partially solves the problem, as it will appear if the user has 4k or 5k indexes. This will be adequately solved in the 0.7 release.
