+# How to write fuzz tests
+
+This document introduces how to write fuzz tests in GreptimeDB.
+
+## What is a fuzz test
+Fuzz test is tool that leverage deterministic random generation to assist in finding bugs. The goal of fuzz tests is to identify inputs generated by the fuzzer that cause system panics, crashes, or unexpected behaviors to occur. And we are using the [cargo-fuzz](https://github.com/rust-fuzz/cargo-fuzz) to run our fuzz test targets. 
+
+## Why we need them
+- Find bugs by leveraging random generation
+- Integrate with other tests (e.g., e2e)
+
+## Resources
+All fuzz test-related resources are located in the `/tests-fuzz` directory.
+There are two types of resources: (1) fundamental components and (2) test targets.
+
+### Fundamental components 
+They are located in the `/tests-fuzz/src` directory. The fundamental components define how to generate SQLs (including dialects for different protocols) and validate execution results (e.g., column attribute validation), etc.
+
+### Test targets
+They are located in the `/tests-fuzz/targets` directory, with each file representing an independent fuzz test case. The target utilizes fundamental components to generate SQLs, sends the generated SQLs via specified protocol, and validates the results of SQL execution.
+
+Figure 1 illustrates the fundamental components of the fuzz test provide the ability to generate random SQLs. It utilizes a Random Number Generator (Rng) to generate the Intermediate Representation (IR), then employs a DialectTranslator to produce specified dialects for different protocols. Finally, the fuzz tests send the generated SQL via the specified protocol and verify that the execution results meet expectations.
+```

+
+## How to add a fuzz test target
+
+1. Create an empty rust source file under the `/tests-fuzz/targets/<fuzz-target>.rs` directory.
+
+2. Register the fuzz test target in the `/tests-fuzz/Cargo.toml` file.
+
+```toml
+[[bin]]
+name = "<fuzz-target>"
+path = "targets/<fuzz-target>.rs"
+test = false
+bench = false
+doc = false
+```
+
+3. Define the `FuzzInput` in the `/tests-fuzz/targets/<fuzz-target>.rs`.
+
+```rust
+#![no_main]
+use libfuzzer_sys::arbitrary::{Arbitrary, Unstructured};
+
+#[derive(Clone, Debug)]
+struct FuzzInput {
+    seed: u64,
+}
+
+impl Arbitrary<'_> for FuzzInput {
+    fn arbitrary(u: &mut Unstructured<'_>) -> arbitrary::Result<Self> {
+        let seed = u.int_in_range(u64::MIN..=u64::MAX)?;
+        Ok(FuzzInput { seed })
+    }
+}
+```
+
+4. Write your first fuzz test target in the `/tests-fuzz/targets/<fuzz-target>.rs`.
+
+```rust
+use libfuzzer_sys::fuzz_target;
+use rand::{Rng, SeedableRng};
+use rand_chacha::ChaChaRng;
+use snafu::ResultExt;
+use sqlx::{MySql, Pool};
+use tests_fuzz::fake::{
+    merge_two_word_map_fn, random_capitalize_map, uppercase_and_keyword_backtick_map,
+    MappedGenerator, WordGenerator,
+};
+use tests_fuzz::generator::create_expr::CreateTableExprGeneratorBuilder;
+use tests_fuzz::generator::Generator;
+use tests_fuzz::ir::CreateTableExpr;
+use tests_fuzz::translator::mysql::create_expr::CreateTableExprTranslator;
+use tests_fuzz::translator::DslTranslator;
+use tests_fuzz::utils::{init_greptime_connections, Connections};
+
+fuzz_target!(|input: FuzzInput| {
+    common_telemetry::init_default_ut_logging();
+    common_runtime::block_on_write(async {
+        let Connections { mysql } = init_greptime_connections().await;
+            let mut rng = ChaChaRng::seed_from_u64(input.seed);
+            let columns = rng.gen_range(2..30);
+            let create_table_generator = CreateTableExprGeneratorBuilder::default()
+                .name_generator(Box::new(MappedGenerator::new(
+                    WordGenerator,
+                    merge_two_word_map_fn(random_capitalize_map, uppercase_and_keyword_backtick_map),
+                )))
+                .columns(columns)
+                .engine("mito")
+                .if_not_exists(if_not_exists)
+                .build()
+                .unwrap();
+            let ir = create_table_generator.generate(&mut rng);
+            let translator = CreateTableExprTranslator;
+            let sql = translator.translate(&expr).unwrap();
+            mysql.execute(&sql).await
+    })
+});
+```
+
+5. Run your fuzz test target
+
+```bash
+    cargo fuzz run <fuzz-target> --fuzz-dir tests-fuzz
+```
+
+For more details, please refer to this [document](/tests-fuzz/README.md).

 # How to use
 
+## `greptimedb.json`
+
 Open Grafana Dashboard page, choose `New` -> `Import`. And upload `greptimedb.json` file.
+
+## `greptimedb-cluster.json`
+
+This cluster dashboard provides a comprehensive view of incoming requests, response statuses, and internal activities such as flush and compaction, with a layered structure from frontend to datanode. Designed with a focus on alert functionality, its primary aim is to highlight any anomalies in metrics, allowing users to quickly pinpoint the cause of errors.
+
+We use Prometheus to scrape off metrics from nodes in GreptimeDB cluster, Grafana to visualize the diagram. Any compatible stack should work too.
+
+__Note__: This dashboard is still in an early stage of development. Any issue or advice on improvement is welcomed.
+
+### Configuration
+
+Please ensure the following configuration before importing the dashboard into Grafana.
+
+__1. Prometheus scrape config__
+
+Assign `greptime_pod` label to each host target. We use this label to identify each node instance.
+
+```yml
+# example config
+# only to indicate how to assign labels to each target
+# modify yours accordingly
+scrape_configs:
+  - job_name: metasrv
+    static_configs:
+    - targets: ['<ip>:<port>']
+      labels:
+        greptime_pod: metasrv
+
+  - job_name: datanode
+    static_configs:
+    - targets: ['<ip>:<port>']
+      labels:
+        greptime_pod: datanode1
+    - targets: ['<ip>:<port>']
+      labels:
+        greptime_pod: datanode2
+    - targets: ['<ip>:<port>']
+      labels:
+        greptime_pod: datanode3
+
+  - job_name: frontend
+    static_configs:
+    - targets: ['<ip>:<port>']
+      labels:
+        greptime_pod: frontend
+```
+
+__2. Grafana config__
+
+Create a Prometheus data source in Grafana before using this dashboard. We use `datasource` as a variable in Grafana dashboard so that multiple environments are supported.
+
+### Usage
+
+Use `datasource` or `greptime_pod` on the upper-left corner to filter data from certain node.

+//! [`SecretBox`] wrapper type for more carefully handling secret values
+//! (e.g. passwords, cryptographic keys, access tokens or other credentials)
+//!
+//! # Goals
+//!
+//! - Make secret access explicit and easy-to-audit via the
+//!   [`ExposeSecret`] and [`ExposeSecretMut`] traits.
+//! - Prevent accidental leakage of secrets via channels like debug logging
+//! - Ensure secrets are wiped from memory on drop securely
+//!   (using the [`zeroize`] crate)
+//!
+//! Presently this crate favors a simple, `no_std`-friendly, safe i.e.
+//! `forbid(unsafe_code)`-based implementation and does not provide more advanced
+//! memory protection mechanisms e.g. ones based on `mlock(2)`/`mprotect(2)`.
+//! We may explore more advanced protection mechanisms in the future.
+//! Those who don't mind `std` and `libc` dependencies should consider using
+//! the [`secrets`](https://crates.io/crates/secrets) crate.
+//!
+//! # `serde` support

+//!
+//! To prevent exfiltration of secret values via `serde`, by default `SecretBox<T>`
+//! does *not* receive a corresponding [`Serialize`] impl. If you would like
+//! types of `SecretBox<T>` to be serializable with `serde`, you will need to impl
