    const instance = bigtable.instance(INSTANCE_NAME);

    // Connect to an existing table:my-table
    const table = instance.table(TABLE_NAME);

    // Read a row from my-table using a row key

Versioning

This library follows Semantic Versioning .

This library is considered to be General Availability (GA) . This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.
