+The sql-files in this folder initialize the ZITADEL database and user. These objects need to exist before ZITADEL is able to set and start up.

+## files
+
+- 01_user.sql: create the user zitadel uses to connect to the database
+- 02_database.sql: create the database for zitadel
+- 03_grant_user.sql: grants the user created before to have full access to its database. The user needs full access to the database because zitadel makes ddl/dml on runtime
+- 04_eventstore.sql: creates the schema needed for eventsourcing
+- 05_projections.sql: creates the schema needed to read the data
+- files 06_enable_hash_sharded_indexes.sql and 07_events_table.sql must run in the same session
+  - 06_enable_hash_sharded_indexes.sql enables the [hash sharded index](https://www.cockroachlabs.com/docs/stable/hash-sharded-indexes.html) feature for this session
+  - 07_events_table.sql creates the table for eventsourcing
