模块配置项
自带配置元数据的模块的键：平台服务（各自是独立的 Spring Boot 应用），以及仅当 wow-cosid、wow-cocache 在类路径上时宿主才读取的 CosId、CoCache 键。每一节由对应模块的 spring-configuration-metadata.json 生成，说明取自源码，为英文；宿主的键见配置项。
Analytics catalog
wow.analytics.catalog
The analytics catalog service's settings, wow.analytics.catalog.*: the warehouse whose tables and views are the sources, the accounts trusted to describe them, how the catalog watches them, and its datasets.
| 键 | 类型 | 默认值 | 说明 |
|---|---|---|---|
wow.analytics.catalog.connection | String | default | The name of the warehouse connection, the first part of each source's id. |
wow.analytics.catalog.databases | List<String> | The databases whose tables and views are sources; wow.clickhouse.database when empty. | |
wow.analytics.catalog.refresh-interval | Duration | PT30S | How often the catalog compares system.tables and wow_catalog with what it saw last and brings each changed table's source up to date. |
wow.analytics.catalog.require-publication-approval | Boolean | false | Whether every publication takes an approver (ApproveDatasetPublication); a publication that computes from sensitive values or lowers a protection takes one either way. |
wow.analytics.catalog.require-source-approval | Boolean | false | Whether a dataset reads only the sources an approver approved (ApproveSource). |
wow.analytics.catalog.trusted-writers | Map<String,List<String>> | By warehouse account, the contexts whose tables the wow_catalog rows of that account are trusted to describe: the account each context's Sink inserts as. Nobody is trusted by default. |
wow.analytics.catalog.datasets
The datasets: where their views are created, how long a retired one is kept, and whether this node serves them.
| 键 | 类型 | 默认值 | 说明 |
|---|---|---|---|
wow.analytics.catalog.datasets.database | String | wow_datasets | The warehouse database the datasets' views are created in. |
wow.analytics.catalog.datasets.reconcile-interval | Duration | PT5M | How often this node reads every published dataset. |
wow.analytics.catalog.datasets.refresh-interval | Duration | PT5S | How often this node reads which published datasets changed. |
wow.analytics.catalog.datasets.retention | Duration | PT168H | How long a retired dataset's views are kept before they are dropped. |
wow.analytics.catalog.datasets.serving
Whether this node serves the published datasets' queries.
| 键 | 类型 | 默认值 | 说明 |
|---|---|---|---|
wow.analytics.catalog.datasets.serving.enabled | Boolean | true | Whether this node serves the published datasets' queries. |
wow.analytics.catalog.watch
How the catalog watches the warehouse for changed tables.
| 键 | 类型 | 默认值 | 说明 |
|---|---|---|---|
wow.analytics.catalog.watch.enabled | Boolean | true | Whether the catalog watches the warehouse for changed tables at all. |
View store
wow.view-store
The view store service's settings (wow.view-store, the 9.x starter's prefix).
| 键 | 类型 | 默认值 | 说明 |
|---|---|---|---|
wow.view-store.system-views | List<SystemViewProperties> | The read-only system views the service serves (ConfiguredSystemViews), each with its tenant-id and app-id (blank for every one), its id (not starting with system:), its definition-id, its title and its config, the engine's view configuration as JSON text. |
CosId
wow.cosid
wow-cosid's settings, wow.cosid.*: the one default of each key, and the class its configuration metadata comes from. The module imports no Spring Boot, so WowCosIdAutoConfiguration reads its key from Spring's Environment, falling back to the default here; the host knows the key from the metadata this module ships.
| 键 | 类型 | 默认值 | 说明 |
|---|---|---|---|
wow.cosid.aggregate-generator | String | default | The CosId generator, by its name in cosid.generators, of the aggregate types that wow.aggregates.[<context>.<aggregate>].id-generator does not name and that have no CosId generator named after them (<context>.<aggregate>): CosId's default generator when not set. It must be one of CosId's generators, or the node does not start. The node's own ids (request, command, wait ids) are never CosId's. |
CoCache
wow.cocache
wow-cocache's settings, wow.cocache.*: the one default of each key, and the class its configuration metadata comes from. The module imports no Spring Boot, so WowCoCacheAutoConfiguration reads its keys from Spring's Environment, falling back to the defaults here; the host knows the keys from the metadata this module ships. A reader's settings of each cache (its local copies, its negative caching, the lifetime of what it fills) are CoCache's own, cocache.caches.[wow.<context>.<aggregate>].*.
| 键 | 类型 | 默认值 | 说明 |
|---|---|---|---|
wow.cocache.publish | List<String> | The aggregate types, <context>.<aggregate>, whose states this service writes into their caches after each commit; each must be one of the service's own, with a state its contract publishes. None when not set: a state no one reads pays no write. | |
wow.cocache.ttl | Duration | How long a state this service writes lives in the cache, a deleted aggregate's tombstone too: the cache's own lifetime (cocache.caches.[wow.<context>.<aggregate>].ttl, else CoCache's default) when not set. A reader's fill lives by the reader's lifetime, so give both sides the same. |
