Expand description
information_schema.table_semantics: the queryable view over the table
semantic layer. One row per table that carries at least one
greptime.semantic.* option, so a consumer can discover the observability
concept a table stands for with a single SQL query instead of parsing every
table’s create_options.
The few signal-agnostic keys are promoted to their own columns
(signal_type / source / source_version / pipeline /
metadata_quality); the remaining signal-specific keys are folded into a
semantic_options JSON string, keyed by the option name with the
greptime.semantic. prefix stripped.
