# `logarchiver init-schema`

Create the ClickHouse archive-index database and table (idempotent).

```sh
logarchiver init-schema           # execute the DDL against index.address
logarchiver init-schema --print   # print the DDL instead of executing it
```

In-cluster the argocd bootstrap Job owns schema creation (a ClickHouse PostSync
hook, mirroring the logging stack's `clickhouse-schema` job). Use
`init-schema --print` to emit the exact `CREATE DATABASE` / `CREATE TABLE`
statements to embed in that Job, and `init-schema` (executing) for local/dev.

The statements are the source-of-truth DDL from `internal/index/ddl.go`, also
kept as [`schema/archive_index.sql`](../schema/archive_index.sql). Database and
table names come from `index.database` / `index.table` (defaults `logs` /
`archive_index`).
