While it has undergone development and review by HashiCorp employees, they may not be as knowledgeable about the technology. ```hcl storage "cockroachdb" { connection_url = "postgres://user123:secret123!@localhost:5432/vault" } ``` **Note** - CockroachDB is compatible with the PostgreSQL database driver and uses that driver to interact with the database. ## `cockroachdb` Parameters - `connection_url` `(string: )` – Specifies the connection string to use to authenticate and connect to CockroachDB. A full list of supported parameters can be found in [the pq library documentation][pglib]. For example connection string URLs, see the examples section below. - `table` `(string: "vault_kv_store")` – Specifies the name of the table in which to write Vault data. This table must already exist (Vault will not attempt to create it). - `max_parallel` `(string: "128")` – Specifies the maximum number of concurrent requests to CockroachDB. ## `cockroachdb` Examples This example shows connecting to a PostgresSQL cluster using full SSL verification (recommended). ```hcl storage "cockroachdb" { connection_url = "postgres://user:pass@localhost:5432/database?sslmode=verify-full" } ``` To disable SSL verification (not recommended), replace `verify-full` with `disable`: ```hcl storage "cockroachdb" { connection_url = "postgres://user:pass@localhost:5432/database?sslmode=disable" } ``` [cockroachdb]: https://www.cockroachlabs.com/ [pglib]: https://godoc.org/github.com/lib/pq#hdr-Connection_String_Parameters
