Andrzej Bialecki commented on NUTCH-907:
-----------------------------------------
That's very good news - in that case I'm fine with the Gora API as it is now,
we should change Nutch to make use of this functionality.
> DataStore API doesn't support multiple storage areas for multiple disjoint
> crawls

> Key: NUTCH-907
> URL: https://issues.apache.org/jira/browse/NUTCH-907
> Project: Nutch
> Issue Type: Bug
> Reporter: Andrzej Bialecki
> Fix For: 2.0
>
>
> In Nutch 1.x it was possible to easily select a set of crawl data (crawldb,
> page data, linkdb, etc) by specifying a path where the data was stored. This
> enabled users to run several disjoint crawls with different configs, but
> still using the same storage medium, just under different paths.
> This is not possible now because there is a 1:1 mapping between a specific
> DataStore instance and a set of crawl data.
> In order to support this functionality the Gora API should be extended so
> that it can create stores (and data tables in the underlying storage) that
> use arbitrary prefixes to identify the particular crawl dataset. Then the
> Nutch API should be extended to allow passing this "crawlId" value to select
> one of possibly many existing crawl datasets.
