## NOTE: Binds on every interface.

## The options to pass to the Solr JVM. Non-standard options,
|

## i.e. -XX, may not be portable across JVM implementations.

## E.g. -XX:+UseCompressedStrings

## The minimum batch size, in number of Riak objects. Any batches that
|

##
|
|
## Acceptable values:

## - an integer
|
|
## search.queue.batch.minimum = 10
|
|
|
|
## The maximum batch size, in number of Riak objects. Any batches that are
|
|
## larger than this amount will be split, where the first
|
|
## search.queue.batch.maximum set of objects will be flushed to Solr, and
|
|
## the remaining objects enqueued for that index will be retained until the
|
|
## next batch is delivered. This parameter ensures that at most
|
|
## "search.queue.batch.maximum object" will be delivered into Solr in any
|
|
## given request.

## Default: 500

## Acceptable values:

## - an integer
|
|
## search.queue.batch.maximum = 500
|
|
|
|
## The maximum delay between notification to flush batches to Solr. This
|
|
## setting is used to increase or decrease the frequency of batch delivery
|
|
## into Solr, specifically for relatively low-volume input into Riak. This
|
|
## setting ensures that data will be delivered into Solr in accordance with
|
|
## the "search.queue.batch.minimum" and "search.queue.batch.maximum"
|
|
## settings within the specified interval. Batches that are smaller than
|
|
## "search.queue.batch.minimum" will be delivered to Solr within this
|
|
## interval. This setting will generally hav no effect on heavily loaded
|
|
## systems.

## Default: 500ms

## Acceptable values:

## - the text "infinity"
|

## search.queue.batch.flush_interval = 500ms
|
|
|
|
## The queue high watermark. If the total number of queued messages in a
|
|
## Solr Queue Worker instance exceeds this limit, then the calling vnode
|
|
## will be blocked until the total number falls below this limit. This
|
|
## parameter exercises flow control between Riak and the Riak
|
|
## Search batching subsystem if writes into Solr start to fall behind.
|
|
##
|
|
## Default: 1000

## The strategy for how we handle purging when we hit the
|
|
## search.queue.high_watermark.
|
|
## - purge_one -> Removes the oldest item on the queue from an
|
|
## erroring (references to fuses blown in the code) index in
|
|
## order to get below the search.queue.high_watermark.
|
|
## - purge_index -> Removes all items associated with one random
|
|
## erroring (references to fuses blown in the code) index in
|
|
## order to get below the search.queue.high_watermark.
|
|
## - off -> purging is disabled
