Tables and schemas used by ClickStack
The ClickStack OpenTelemetry (OTel) collector uses the ClickHouse exporter to create tables in ClickHouse and insert data.
The following tables are created for each data type in the default database. Users can change this target database by modifying the environment variable HYPERDX_OTEL_EXPORTER_CLICKHOUSE_DATABASE for the image hosting the OTel collector.

Note
HyperDX does not support fetching/displaying exponential histogram metrics yet. Users may configure them in the metrics source but future support is forthcoming.
