+# CockroachDB Driver
+
+This is a driver for CockroachDB. It extends the generic JDBC Driver and
+inherits its parameters.
+
+### CockroachDB driver parameters
+
+All parameters correspond to the postgresql JDBC library parameters. See
+the
+[DataSource Configuration Properties](https://jdbc.postgresql.org/documentation/81/ds-ds.html)
+section for detailed parameter documentation.
+
+* **serverName** (required) - database hostname
+* **portNumber** (optional) - database listen port; defaults to 26257.
+* **user** (optional) - database account username; defaults to empty.
+* **password** (optional) - database account password; defaults to empty.
+* **connectionpool** (optional) - connection pool implementation; defaults
+  to no connection pool. Allowed values:
+    * *hikari* -
+      use [HikariCP](https://github.com/brettwooldridge/HikariCP)
