How to read tlog

[Subhajit Das]

Hi There,

I faced a issue, on a core, in multicore standalone instance.
Is there any way to read tlog contents as text files. This might help to 
resolve the issue.
Thanks in advance.

What guarantees does solr have for keeping commit deadlines?

[Nándor Mátravölgyi]

Hi!

I'm working on building a NRT solr instance. The schema is designed so
documents can be partially updated. Some documents will need to
receive or lose filter tags in a multi-valued field.

I have to be able to query already existing documents to add tags to
them or remove tags from them. Obviously if I (soft-)commit after each
document is added or removed the serializable consistency would
guarantee that I can see all documents that I might want to change.
However this is not desirable in terms of performance.

I've come up with a potential solution: If I can track document
updates that I make and only call commit before I would query
documents that have been changed recently, the performance is not
sacrificed and I will get the strict consistency where I need it. For
this to work reliably the soft-auto-commit interval and the times
specified through commit-within must strictly comply with the config
and the requests.

I have auto-commit interval of 60 seconds with open-searcher false and
auto-soft-commit interval of 15 seconds. Documents will be submitted
through the REST API where some of them will also have commit-within
2-3 seconds specified.

My questions:
 - After a document indexing request has returned with success, what
level of guarantee do I have that the document will be available after
the configured soft-commit-interval?
 - After a document indexing request with commit-within has returned
with success, what level of guarantee do I have that the document will
be available after the requested commit timeout?
 - Alternatively if I could query solr when the last soft-commit was
done I could ensure to call a soft-commit myself. Is there an API to
see when or how long ago was the last (soft-)commit?

I'm primarily interested in answers regards to solr in standalone mode.

Thanks,
Nandor
