-# Redis
+# Redis Sink
 
-A Redis sink Firehose \(`SINK_TYPE`=`redis`\) requires the following variables to be set along with Generic ones
+Redis Sink is implemented in Firehose using the Redis sink connector implementation in ODPF Depot. You can check out ODPF Depot Github repository [here](https://github.com/odpf/depot).
 
-### `SINK_REDIS_URLS`
+### Data Types
+Redis sink can be created in 3 different modes based on the value of [`SINK_REDIS_DATA_TYPE`](https://github.com/odpf/depot/blob/main/docs/reference/configuration/redis.md#sink_redis_data_type): HashSet, KeyValue or List
+- `Hashset`: For each message, an entry of the format `key : field : value` is generated and pushed to Redis. Field and value are generated on the basis of the config [`SINK_REDIS_HASHSET_FIELD_TO_COLUMN_MAPPING`](https://github.com/odpf/depot/blob/main/docs/reference/configuration/redis.md#sink_redis_hashset_field_to_column_mapping)
+- `List`: For each message entry of the format `key : value` is generated and pushed to Redis. Value is fetched for the Proto field name provided in the config [`SINK_REDIS_LIST_DATA_FIELD_NAME`](https://github.com/odpf/depot/blob/main/docs/reference/configuration/redis.md#sink_redis_list_data_field_name)
+- `KeyValue`: For each message entry of the format `key : value` is generated and pushed to Redis. Value is fetched for the proto field name provided in the config [`SINK_REDIS_KEY_VALUE_DATA_FIELD_NAME`](https://github.com/odpf/depot/blob/main/docs/reference/configuration/redis.md#sink_redis_key_value_data_field_name)
 
-REDIS instance hostname/IP address followed by its port.
+The `key` is picked up from a field in the message itself.
 
-- Example value: `localhos:6379,localhost:6380`
-- Type: `required`
+Limitation: Depot Redis sink only supports Key-Value, HashSet and List entries as of now.
 
-### `SINK_REDIS_DATA_TYPE`
+### Configuration
 
-To select whether you want to push your data as a HashSet or as a List.
+For Redis sink in Firehose we need to set first (`SINK_TYPE`=`redis`). 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). Redis sink specific configs are mentioned in ODPF Depot repository. You can check out the Redis Sink configs [here](https://github.com/odpf/depot/blob/main/docs/reference/configuration/redis.md)
 
-- Example value: `Hashset`
-- Type: `required`
-- Default value: `List`
 
-### `SINK_REDIS_KEY_TEMPLATE`
-
-The string that will act as the key for each Redis entry. This key can be configured as per the requirement, a constant or can extract value from each message and use that as the Redis key.
-
-- Example value: `Service\_%%s,1`
-
-  This will take the value with index 1 from proto and create the Redis keys as per the template\
-
-- Type: `required`
-
-### `INPUT_SCHEMA_PROTO_TO_COLUMN_MAPPING`
-
-This is the field that decides what all data will be stored in the HashSet for each message.
-
-- Example value: `{"6":"customer_id", "2":"order_num"}`
-- Type: `required (For Hashset)`
-
-### `SINK_REDIS_LIST_DATA_PROTO_INDEX`
-
-This field decides what all data will be stored in the List for each message.
-
-- Example value: `6`
-
-  This will get the value of the field with index 6 in your proto and push that to the Redis list with the corresponding keyTemplate\
-
-- Type: `required (For List)`
-
-### `SINK_REDIS_KEY_VALUE_DATA_PROTO_INDEX`
-
-This field decides what data will be stored in the value part of key-value pair
-
-- Example value: `6`
-
-  This will get the value of the field with index 6 in your proto and push that to the Redis as value with the corresponding keyTemplate\
-
-- Type: `required (For KeyValue)`
-
-### `SINK_REDIS_TTL_TYPE`
-
-- Example value: `DURATION`
-- Type: `optional`
-- Default value: `DISABLE`
-- Choice of Redis TTL type.It can be:\
-  - `DURATION`: After which the Key will be expired and removed from Redis \(UNIT- seconds\)\
-  - `EXACT_TIME`: Precise UNIX timestamp after which the Key will be expired
-
-### `SINK_REDIS_TTL_VALUE`
-
-Redis TTL value in Unix Timestamp for `EXACT_TIME` TTL type, In Seconds for `DURATION` TTL type.
-
-- Example value: `100000`
-- Type: `optional`
-- Default value: `0`
-
-### `SINK_REDIS_DEPLOYMENT_TYPE`
-
-The Redis deployment you are using. At present, we support `Standalone` and `Cluster` types.
-
-- Example value: `Standalone`
-- Type: `required`
-- Default value: `Standalone`
+### Deployment Types
+Redis sink, as of now, supports two different Deployment Types `Standalone` and `Cluster`. This can be configured in the Depot environment variable `SINK_REDIS_DEPLOYMENT_TYPE`.
