+# StarRocks
+
+> StarRocks sink connector
+
+## Description
+Used to send data to StarRocks. Both support streaming and batch mode.
+The internal implementation of StarRocks sink connector is cached and imported
by stream load in batches.
+## Key features
+
+- [ ] [exactly-once](../../concept/connector-v2-features.md)
+- [ ] [schema projection](../../concept/connector-v2-features.md)
+
+## Options

|
+
+### node_urls [list]
+
+`StarRocks` cluster address, the format is `["fe_ip:fe_http_port", ...]`
+
+### username [string]
+
+`StarRocks` user username
+
+### password [string]
+
+`StarRocks` user password
+
+### database [string]
+
+The name of StarRocks database
+
+### table [string]
+
+The name of StarRocks table
+
+### labelPrefix [string]
+
+the prefix of StarRocks stream load label
+
+### batch_max_rows [string]
+
+For batch writing, when the number of buffers reaches the number of
`batch_max_rows` or the byte size of `batch_max_bytes` or the time reaches
`batch_interval_ms`, the data will be flushed into the StarRocks
+
+### batch_max_bytes [string]
+
+For batch writing, when the number of buffers reaches the number of
`batch_max_rows` or the byte size of `batch_max_bytes` or the time reaches
`batch_interval_ms`, the data will be flushed into the StarRocks
+
+### batch_interval_ms [string]
+
+For batch writing, when the number of buffers reaches the number of
`batch_max_rows` or the byte size of `batch_max_bytes` or the time reaches
`batch_interval_ms`, the data will be flushed into the StarRocks
+
+### max_retries [string]
+
+The number of retries to flush failed
+
+### retry_backoff_multiplier_ms [string]
+
+Using as a multiplier for generating the next delay for backoff
+
+### max_retry_backoff_ms [string]
+
+The amount of time to wait before attempting to retry a request to `StarRocks`
+
+### sink.properties.* [starrocks stream load config]
+
+the parameter of the stream load `data_desc`
+The way to specify the parameter is to add the prefix `sink.properties.` to
the original stream load parameter name.
+For example, the way to specify `strip_outer_array` is:
`sink.properties.strip_outer_array`.
+
+#### Supported import data formats
+
+The supported formats include CSV and JSON. Default value: CSV
+
+## Example
+Use JSON format to import data
+```
+sink {
+ StarRocks {
+ nodeUrls = ["e2e_starRocksdb:8030"]
+ username = root
+ password = ""
+ database = "test"
+ table = "e2e_table_sink"
+ batch_max_rows = 10
+ sink.properties.format = "JSON"
+ sink.properties.strip_outer_array = true
+ }
+}
+
+```
+
+Use CSV format to import data
+```
+sink {
+ StarRocks {
+ nodeUrls = ["e2e_starRocksdb:8030"]
+ username = root
+ password = ""
+ database = "test"
+ table = "e2e_table_sink"
+ batch_max_rows = 10
+ sink.properties.format = "CSV"
+ sink.properties.column_separator = "\\x01",
+ sink.properties.row_delimiter = "\\x02"
+ }
+}
+```
