Blockchain database tends to grow over time, depending e.g. on block speed and transaction amount. For qubetics, we are talking about close to 100GB of disk usage in first two weeks. There are few configurations that can be done to reduce the required disk usage quite significantly. Some of these changes take full effect only when you do the configuration and start syncing from start with them in use. ### Indexing If you do not need to query transactions from the specific node, you can disable indexing. On `config.toml` set ```toml indexer = "null" ``` If you do this on already synced node, the collected index is not purged automatically, you need to delete it manually. The index is located under the database directory with name `data/tx_index.db/`. ### Configure pruning By default every 500th state, and the last 100 states are kept. This consumes a lot of disk space on long run, and can be optimized with following custom configuration: ```toml pruning = "custom" pruning-keep-recent = "1000" pruning-interval = "10" ``` Configuring `pruning-keep-recent = "0"` might sound tempting, but this will risk database corruption if the `qubeticsd` is killed for any reason. Thus, it is recommended to keep the few latest states. ### Logging By default the logging level is set to `info`, and this produces a lot of logs. This log level might be good when starting up to see that the node starts syncing properly. However, after you see the syncing is going smoothly, you can lower the log level to `warn` (or `error`). On `config.toml` set the following ```toml log_level = "warn" ``` --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://qubetics.gitbook.io/qubetics-docs/getting-started/publish-your-docs-5.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
