A local emulator for Cloud Bigtable with persistence to a sqlite3 backend.
The Cloud SDK provided cbtemulator is in-memory and does not support persistence which limits it's applicability. This project is a fork of cbtemulator from google-cloud-go/bigtable/bttest

In the environment for your application, set the BIGTABLE_EMULATOR_HOST environment variable to the host and port where little_bigtable is running. This environment variable is automatically detected by the Bigtable SDK or the cbt CLI. For example:
$ export BIGTABLE_EMULATOR_HOST="127.0.0.1:9000"
$ ./run_my_appSome filters are not implemented or have partial support. See cbtemulator docs
This tool is heavily optimized to suite the needs of the beaconcha.in project and is no longer a general purpose bigtable emulator.
