Layer v0.7.3

Highlights

• Telemetry reports usage and who started the gateway. The anonymous gateway_heartbeat now carries a usage block: successful queries, writes, and rows upserted, patched and deleted since the previous heartbeat. The gateway checks hourly and sends a heartbeat only when there is usage to report, or once a day when idle. A tool that starts the gateway can name itself with LAYER_TELEMETRY_SOURCE and LAYER_TELEMETRY_SOURCE_VERSION. Telemetry still never includes query text, vectors, namespace names, document IDs, keys or contents, and LAYER_TELEMETRY=off or DO_NOT_TRACK=1 turns it off. (layer-pro#688)

Docs

• The observability page describes what telemetry sends, how often, the source variables, and how to opt out, including the Helm chart's gateway.telemetry.enabled value.

Clients

• The Python, TypeScript and Go clients are published at 0.7.3.
