There are three configuration files cn.toml, dn.toml and log.toml in the matrixone/etc/launch-tae-CN-tae-DN/ directory.
The parameters contained in each configuration file are explained as follows:
cn.toml
| Parameters | Description |
|---|---|
| service-type = “CN” | Node Type |
| data-dir = “./mo-data” | Default data directory |
| [log] | |
| level = “info” | Log level, can be modified to info/debug/error/faltal |
| format = “console” | Log format |
| max-size = 512 | Log default length |
| [hakeeper-client] | HAkeeper default address and port, not recommended to change |
| service-addresses = [ “127.0.0.1:32001”, ] | |
| [metacache] | Metadata Cache |
| memory-capacity = “512MB” | Set the cache size for metadata, default is 512MB. The data caching feature results in slower first-time queries, but subsequent queries will be faster. |
| [[fileservice]] | fileservice, not recommended to change |
| name = “LOCAL” | fileservice storage type, local storage |
| backend = “DISK” | fileservice backend, disk |
| [[fileservice]] | |
| name = “SHARED” | fileservice storage type, S3 |
| backend = “DISK” | fileservice backend, disk |
| data-dir = “mo-data/s3” | s3 storage data directory |
| [fileservice.cache] | |
| memory-capacity = “512MB” | cache memory size used by fileservice |
| disk-capacity = “8GB” | cache disk size used by fileservice |
| disk-path = “mo-data/file-service-cache” | fileservice disk cache path |
| disk-min-evict-interval = “7m” | Interval for disk cache recovery, in seconds (s) or minutes (m) |
| disk-evict-target = 0.8 | Target capacity for disk cache recovery, parameter is the ratio of template capacity to total capacity |
| [[fileservice]] | |
| name = “ETL” | fileservice storage type, ETL |
| backend = “DISK-ETL” | fileservice backend, DISK-ETL |
| [observability] | Observability parameter, disabled by default |
| disableTrace = true | |
| disableMetric = true | |
| [cn] | cn code number, cannot be modified |
| uuid = “dd1dccb4-4d3c-41f8-b482-5251dc7a41bf” | |
| [cn.Engine] | Storage engine of the cn node, distributed tae, cannot be modified |
| type = “distributed-tae” | |
| [cn.txn] | |
| enable-sacrificing-freshness = false | When set to true and push mode, this parameter does not guarantee that a transaction can see the latest committed data. Instead, it uses the latest Logtail commit timestamp received by the current CN as the transaction start time. This setting ensures that a transaction on the same database connection can see the data written by its previously committed transactions. |
| enable-cn-based-consistency = false | When the above parameter is set to true, it ensures external consistency on the same CN. When a transaction starts, it can see the data written by previously committed transactions. |
