Hoss Man commented on SOLR-445:
-------------------------------
bq. . The errors are managed by an UpdateRequestProcessor that must be added
before other processors in the chain.
Off the cuff: this sounds like a great idea.
The on piece of feedback that occurred to me though would be to tweak the
response format so that there is a 1-to-1 correspondence of documents in the
initial request to statuses in the response -- even if the schema doesn't use
uniqueKey...
{code}
<lst name="responseHeader">
<int name="numErrors">10</int>
<lst name="results">
<!-- if schema has uniqueKeys, they are the names of the response -->
<lst name="42" /> <!-- success so empty -->
<lst name="1"> <!-- 2nd doc in update, with uniqueKey of 1 had this failure
-->
<str name="message">ERROR: [doc=1] Error adding field 'weight'='b'
msg=For input string: "b"</str>
</lst>
<lst name="60" /> <!-- success so empty -->
<lst name="3"> <!-- 4th doc in update, with uniqueKey of 3 had this failure
-->
<str name="message">ERROR: [doc=3] Error adding field 'weight'='b'
msg=For input string: "b"</str>
</lst>
...
<int name="status">0</int>
<int name="QTime">17</int>
</lst>
{code}

> Has anyone run into the problem of handling bad documents / failures mid
> batch. Ie:
> <add>
> <doc>
> <field name="id">1</field>
> </doc>
> <doc>
> <field name="id">2</field>
> <field name="myDateField">I_AM_A_BAD_DATE</field>
> </doc>
> <doc>
> <field name="id">3</field>
> </doc>
> </add>
> Right now solr adds the first doc and then aborts. It would seem like it
> should either fail the entire batch or log a message/return a code and then
> continue on to add doc 3. Option 1 would seem to be much harder to
> accomplish and possibly require more memory while Option 2 would require more
> information to come back from the API. I'm about to dig into this but I
> thought I'd ask to see if anyone had any suggestions, thoughts or comments.
