# تاتر-کپی {#clickhouse-copier}
|
||
|
||
کپی داده ها از جداول در یک خوشه به جداول در یکی دیگر از (یا همان) خوشه.
|
||
|
||
شما می توانید چند اجرا `clickhouse-copier` نمونه بر روی سرور های مختلف برای انجام همان کار. باغ وحش برای همگام سازی فرایندها استفاده می شود.
|
||
|
||
پس از شروع, `clickhouse-copier`:
|
||
|
||
- قابلیت اتصال به باغ وحش و دریافت:
|
||
|
||
- شغل کپی.
|
||
- دولت از مشاغل کپی.
|
||
|
||
- این کار را انجام می دهد.
|
||
|
||
هر فرایند در حال اجرا را انتخاب “closest” سفال از خوشه منبع و کپی داده ها را به خوشه مقصد, تغییر شکل داده ها در صورت لزوم.
|
||
|
||
`clickhouse-copier` تغییرات باغ وحش را دنبال می کند و در پرواز اعمال می شود.
|
||
|
||
برای کاهش ترافیک شبکه توصیه می کنیم در حال اجرا `clickhouse-copier` در همان سرور که داده های منبع واقع شده است.
|
||
|
||
## در حال اجرا تاتر-کپی {#running-clickhouse-copier}
|
||
|
||
ابزار باید به صورت دستی اجرا شود:
|
||
|
||
``` bash
|
||
$ clickhouse-copier copier --daemon --config zookeeper.xml --task-path /task/path --base-dir /path/to/dir
|
||
```
|
||
|
||
پارامترها:
|
||
|
||
- `daemon` — Starts `clickhouse-copier` در حالت شبح.
|
||
- `config` — The path to the `zookeeper.xml` فایل با پارامترهای اتصال به باغ وحش.
|
||
- `task-path` — The path to the ZooKeeper node. This node is used for syncing `clickhouse-copier` پردازش و ذخیره سازی وظایف. وظایف در ذخیره می شود `$task-path/description`.
|
||
- `task-file` — Optional path to file with task configuration for initial upload to ZooKeeper.
|
||
- `task-upload-force` — Force upload `task-file` حتی اگر گره در حال حاضر وجود دارد.
|
||
- `base-dir` — The path to logs and auxiliary files. When it starts, `clickhouse-copier` ایجاد `clickhouse-copier_YYYYMMHHSS_<PID>` زیرشاخه در `$base-dir`. اگر این پارامتر حذف شده است, دایرکتوری ها در دایرکتوری که ایجاد `clickhouse-copier` راه اندازی شد.

`clickhouse-copier` پیگیری تغییرات در `/task/path/description` و اونا رو تو پرواز بکار میبره برای مثال, اگر شما ارزش تغییر `max_workers` تعداد فرایندهای در حال اجرا وظایف نیز تغییر خواهد کرد.
