sqliteexporter

Sqlite exporter for the OpenTelemetry Collector and OpenTelemetry Go.

Note that this is an alpha release, tables and column names may change in the future. golang-migrate is used to manage updates to the database schema.

Configuration Options

• path [no default]: Path to the Sqlite database file. If the file does not exist, it will be created on startup.

Example

exporters:
  sqlite:
    path: local.db

Tables

Currently, this exporter creates 3 tables to store trace span data:

• spans: Each individual spans
• events: Span events, with a span_id to JOIN with the spans table
• links: Span links, with a parent_span_id to JOIN with the spans table

The Resource and Instrumentation Library are inlined in the spans table. This creates some duplication but makes the schema much easier to navigate and query. Attributes are inlined as JSON-encoded string and can be queried using Sqlite's JSON functions and operators.

Note on JSONB data type

Sqlite recently added support for the JSONB data type which improves performance on JSON-encoded data. Support for this feature is planned for the future.
