+- it requires the following environment [variables](https://github.com/odpf/depot/blob/main/docs/reference/configuration/bigtable.md) ,which are required by ODPF Depot library, to be set along with the generic firehose variables.

 If you'd like to connect to a sink which is not yet supported, you can create a new sink by following the [contribution guidelines](../contribute/contribution.md)

+# Bigtable Sink
+
+Bigtable Sink is implemented in Firehose using the Bigtable sink connector implementation in ODPF Depot. You can check out ODPF Depot Github repository [here](https://github.com/odpf/depot).
+
+### Configuration
+
+For Bigtable sink in Firehose we need to set first (`SINK_TYPE`=`bigtable`). There are some generic configs which are common across different sink types which need to be set which are mentioned in [generic.md](../advance/generic.md). Bigtable sink specific configs are mentioned in ODPF Depot repository. You can check out the Bigtable Sink configs [here](https://github.com/odpf/depot/blob/main/docs/reference/configuration/bigtable.md)
