-### Complete Feature Set Overview
+#### Custom Data Processing
 
-While the above examples cover basic usage, `@push.rocks/smartclickhouse` offers a wide range of functionalities, including but not limited to:
+To handle complex data structures or to perform custom data processing before insertion, you might need to modify the `addData` method. Below is an example of extending the `SmartClickHouseDb` method:
 
-- Robust error handling and reconnection strategies
-- Efficient bulk data insertion mechanisms
-- Support for ClickHouse specific features like materialized views and aggregating MergeTree engines
-- Techniques for managing and querying large time-series datasets
+```typescript
+class CustomClickHouseDb extends SmartClickHouseDb {
+  public async addCustomData(tableName: string, data: any) {
+    const table = await this.getTable(tableName);
+    const customData = {
+      ...data,

+      customField: 'customValue',
+    };
+    await table.addData(customData);
+  }
+}

+const customDbInstance = new CustomClickHouseDb({
+  url: 'http://localhost:8123',
+  database: 'yourDatabase',
+});
+
+await customDbInstance.start();
+
+await customDbInstance.addCustomData('customTable', {
+  message: 'Test message',
+  randomField: 123456,
+});
+```
+
+### Bulk Data Insertion
+
+`@push.rocks/smartclickhouse` supports efficient bulk data insertion mechanisms. This feature is useful when you need to insert a large amount of data in a single operation.
+
+```typescript
+const bulkData = [
+  { timestamp: Date.now(), message: 'Message 1', temperature: 20.1 },
+  { timestamp: Date.now(), message: 'Message 2', temperature: 21.2 },
+  // Additional data entries...
+];
+
+await table.addData(bulkData);
+```
+
+### Querying Data
+
+Fetching data from the ClickHouse database includes operations such as retrieving the latest entries, entries within a specific timestamp range, or streaming new entries.
+
+#### Retrieving the Last N Entries
+
+To retrieve the last `N` number of entries:
+
+```typescript
+const latestEntries = await table.getLastEntries(10);
+console.log('Latest Entries:', latestEntries);
+```
+
+#### Retrieving Entries Newer than a Specific Timestamp
+
+To retrieve entries that are newer than a specific timestamp:
+
+```typescript
+const timestamp = Date.now() - 60000; // 1 minute ago
+const newEntries = await table.getEntriesNewerThan(timestamp);
+console.log('New Entries:', newEntries);
+```
+
+#### Retrieving Entries Between Two Timestamps
+
+To retrieve entries between two timestamps:
+
+```typescript
+const startTimestamp = Date.now() - 120000; // 2 minutes ago
+const endTimestamp = Date.now() - 5000; // 5 seconds ago
+const entriesBetween = await table.getEntriesBetween(startTimestamp, endTimestamp);
+console.log('Entries Between:', entriesBetween);
+```
+
+### Managing and Deleting Data
+
+The module provides functionality for managing and deleting data within the ClickHouse database.
+
+#### Deleting Old Entries
+
+You can delete entries older than a specified number of days:
+
+```typescript
+// Ensure there are entries before deletion
+let entries = await table.getLastEntries(1000);
+console.log('Entries before deletion:', entries.length);
+
+// Delete all entries older than now
+await table.deleteOldEntries(0);
+
+// Verify the entries are deleted
+entries = await table.getLastEntries(1000);
+console.log('Entries after deletion:', entries.length);
+```
+
+#### Deleting the Entire Table
+
+To delete the entire table and all its data:
+
+```typescript
+await table.delete();
+
+// Verify table deletion
+const result = await dbInstance.clickhouseHttpClient.queryPromise(`
+  SHOW TABLES FROM ${dbInstance.options.database} LIKE '${table.options.tableName}'
+`);
+console.log('Table exists after deletion:', result.length === 0);
+```
+
+### Observing Real-Time Data
+
+To observe new entries in real-time, you can stream new data entries using the RxJS Observable:
+
+```typescript
+const stream = table.streamNewEntries();
+
+const subscription = stream.subscribe((entry) => {
+  console.log('New entry:', entry);
+});
+
+// Simulate adding new entries
+let i = 0;
+while (i < 10) {
+  await table.addData({
+    timestamp: Date.now(),
+    message: `streaming message ${i}`,
+  });
+  i++;
+  await new Promise((resolve) => setTimeout(resolve, 1000)); // Add a delay to simulate real-time data insertion
+}
+
+subscription.unsubscribe();
+```
+
+This method allows continuous monitoring of data changes and integrating the collected data into other systems for real-time applications.
+
+### Comprehensive Feature Set
+
+While the examples provided cover the core functionalities of the `@push.rocks/smartclickhouse` module, it also offers a wide range of additional features, including:
+
