(constructor)(opts, gaxInstance)
constructor

Construct an instance of BigtableClient.

typeof gax
| typeof fallback
: loaded instance of google-gax
. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new BigtableClient({fallback: 'rest'}, gax); ```
