[LUCENE-2701] Factor maxMergeSize into findMergesForOptimize in LogMergePolicy - Lucene - [issue]
|
|
...LogMergePolicy allows you to specify a maxMergeSize in MB, which is taken into consideration in regular merges, yet ignored by findMergesForOptimze. I think it'd be good if we take...
|
|
... that into consideration even when optimizing. This will allow the caller to specify two constraints: maxNumSegments and maxMergeMB. Obviously both may not be satisfied, and therefore we will guarantee...

LogMergePolicy.setUseCompoundFile/DocStore - Lucene - [mail # dev]

...Hi I find it very annoying that I need to set true/false on these methods whenever I want to control compound files creation. Is it really necessary to allow writing doc stores in non ...

[LUCENE-2331] Add NoOpMergePolicy - Lucene - [issue]

... to prevent merges, set mergeFactor to a high enough value". I think a NoOpMergePolicy is just as good, and can REALLY allow you disable merges (except for maybe set mergeFactor to Int...

....MAX_VAL).
As such, NoOpMergePolicy will be introduced as a singleton, and can be used for convenience purposes only. Also, for Parallel Index it's important, because I'd like the slices to never do any...

I have a patch ready. Waiting for LUCENE-2320 to go in, so that I don't need to change it afterwards.

[LUCENE-2320] Add MergePolicy to IndexWriterConfig - Lucene - [issue]

...Now that IndexWriterConfig is in place, I'd like to move MergePolicy to it as well. The change is not straightforward and so I've kept it for a separate issue. MergePolicy requires in its...

MergePolicy and IndexWriter methods argument - Lucene - [mail # dev]

...Hi While reading LogMergePolicy I noticed that it uses IndexWriter's member and method arg inconsistently: 1) Some methods that receive IW as a parameer, do: this.indexWriter index...

[LUCENE-2377] Enable the use of NoMergePolicy and NoMergeScheduler by Benchmark - Lucene - [issue]

Re: Index size and performance degradation - Lucene - [mail # user]
