=== Settings changes
|
|
|
|
|
|
|
|
|
|
==== Percolator
|
|
|
|
|
|
|
|
|
|
* The deprecated `index.percolator.map_unmapped_fields_as_string` setting has been removed in favour of
|
2018-04-18 09:18:08 -04:00
|
|
|
the `index.percolator.map_unmapped_fields_as_text` setting.
|
|
|
|
|
|
|
|
|
|
==== Index thread pool
|
|
|
|
|
|
|
|
|
|
* Internally, single-document index/delete/update requests are executed as bulk
|
|
|
|
|
requests with a single-document payload. This means that these requests are
|
|
|
|
|
executed on the bulk thread pool. As such, the indexing thread pool is no
|
|
|
|
|
longer needed and has been removed. As such, the settings
|
2018-04-19 16:59:58 -04:00
|
|
|
`thread_pool.index.size` and `thread_pool.index.queue_size` have been removed.
|
|
|
|
|
|
|
|
|
|
[[write-thread-pool-fallback]]
|
|
|
|
|
==== Write thread pool fallback
|
|
|
|
|
|
|
|
|
|
* The bulk thread pool was replaced by the write thread pool in 6.3.0. However,
|
|
|
|
|
for backwards compatibility reasons the name `bulk` was still usable as fallback
|
|
|
|
|
settings `thread_pool.bulk.size` and `thread_pool.bulk.queue_size` for
|
|
|
|
|
`thread_pool.write.size` and `thread_pool.write.queue_size`, respectively, and
|
|
|
|
|
the system property `es.thread_pool.write.use_bulk_as_display_name` was
|
|
|
|
|
available to keep the display output in APIs as `bulk` instead of `write`.
|
|
|
|
|
These fallback settings and this system property have been removed.
