Using OutbackCDX with pywb
|
||
|
|
==========================
|
||
|
|
|
||
|
|
The recommended setup is to run `OutbackCDX <https://github.com/nla/outbackcdx>`_ alongside pywb.
|
||
|
|
OutbackCDX provides an index (CDX) server and can efficiently store and look up web archive data by URL.
|
||
|
|
|
||
|
|
|
||
|
|
Adding CDX to OutbackCDX
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
To set up OutbackCDX, please follow the instructions on the `OutbackCDX README <https://github.com/nla/outbackcdx>`_.
|
||
|
|
|
||
|
|
Since pywb also uses the default port 8080, be sure to use a different port for OutbackCDX, eg. ``java -jar outbackcdx*.jar -p 8084``.
|
||
|
|
|
||
|
|
OutbackCDX can generally ingest existing CDX used in OpenWayback simply by POSTing to OutbackCDX at a new index endpoint.
|
||
|
|
|
||
|
|
For example, assuming OutbackCDX is running on port 8084, to add CDX for ``index1.cdx``, ``index2.cdx``, run:
|
||
|
|
|
||
|
|
.. code:: console
|
||
|
|
|
||
|
|
curl -X POST --data-binary @index1.cdx http://localhost:8084/mycoll
|
||
|
|
curl -X POST --data-binary @index2.cdx http://localhost:8084/mycoll
|
||
|
|
|
||
|
|
The contents of each CDX file are added to the ``mycoll`` OutbackCDX index, which can correspond to the web archive collection ``mycoll``.
|
||
|
|
The index is created automatically if it does not exist.
|
||
|
|
|
||
|
|
See the `OutbackCDX Docs <https://github.com/nla/outbackcdx#loading-records>`_ for more info on ingesting CDX.
|
||
|
|
|
||
|
|
|
||
|
|
(Re)generating CDX from WARCs
|
||
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
There are some exceptions where it may be useful to re-generate the CDX with pywb for existing WARCs:
|
||
|
|
|
||
|
|
- If your CDX is 9-field and does not include the compressed length, regnerating the CDX will result in more efficient HTTP range requests
|
||
|
|
- If you want to replay pages with POST requests, pywb generated CDX will soon be supported in OutbackCDX (see: `Issue #585 <https://github.com/webrecorder/pywb/issues/585>`_, `Issue #91 <https://github.com/nla/outbackcdx/pull/91>`_ )
|
||
|
|
|
||
|
|
|
||
|
|
To generate the CDX, run the ``cdx-indexer`` command (with ``-p`` flag for POST request handling) for each WARC or set of WARCs you wish to index:
|
||
|
|
|
||
|
|
.. code:: console
|
||
|
|
|
||
|
|
cdx-indexer /path/to/mywarcs/my.warc.gz > ./index1.cdx
|
||
|
|
cdx-indexer /path/to/all_warcs/*warc.gz > ./index2.cdx
|
||
|
|
|
||
|
|
|
||
|
|
Then, run the POST command as shown above to ingest to OutbackCDX.
|
||
|
|
|
||
|
|
The above can be repeated for each WARC file, or for a set of WARCs using the ``*.warc.gz`` wildcard.
|
||
|
|
|
||
|
|
If a CDX index is too big, OutbackCDX may fail and ingesting an index per-WARC may be needed.
|
||
|
|
|
||
|
|
|
||
|
|
Configure pywb with OutbackCDX
|
||
|
|
------------------------------
|
||
|
|
|
||
|
|
The ``config.yaml`` should be configured to point to OutbackCDX.
|
||
|
|
|
||
|
|
Assuming a collection named ``mycoll``, the ``config.yaml`` can be configured as follows to use OutbackCDX
|
||
|
|
|
||
|
|
|
||
|
|
.. code:: yaml
|
||
|
|
|
||
|
|
collections:
|
||
|
|
mycoll:
|
||
|
|
index_paths: cdx+http://localhost:8084/mycoll
|
||
|
|
archive_paths: /path/to/mywarcs/
|
||
|
|
|
||
|
|
|
||
|
|
The ``archive_paths`` can be configured to point to a directory of WARCs or a path index.
|
