- "sliding window" time filters, e.g drop all documents older than 2 years (aka: who uses old libraries?)
Is "document" the same as "maven artifact" here? Perhaps an additional condition could be added, "older than 1 year _and_ there are newer versions of this artifact in the cache". -- Eirik -----Original Message----- From: Michael Bien <[email protected]> Sent: Friday, March 17, 2023 8:26 PM To: [email protected]; Antonio <[email protected]> Subject: Re: maven indexing tweaks On 17.03.23 22:38, Antonio wrote: > Hi, > > These are impressive savings! yeah I am pretty happy about the results too. Esp the removal of the sha1 field had a great effect. Technically we do actually offer this as query through the public API, however, it doesn't appear as anything is using it - i have to take another look just to be sure. Even if something does we could make it an option in the settings. > > > Out of curiosity, we don't build the index incrementally using Maven's > IndexReader, do we? That's why we download the whole index, right? first use will download the whole copy, weekly updates are incremental. And yes it uses DefaultIndexReader (and the updater) of the maven-indexer project. Which is the reason why we have to make some tweaks upstream to get more flexibility (and filtering). For example some time in future we might want to change where the temp extraction storage is, which maven-indexer uses, which is also part of the proposed PR upstream right now. https://repo1.maven.org/maven2/.index/ has the compressed data for central, (apache etc have their own locations but those indices are smaller so you barely notice anything) Currently the lucene index isn't moved into new NetBeans config from old caches. This is something we could take a look at too but things like this are super annoying to test + risky since someone will find a way to import an index from a 10 year old backup and report that something fails (just like users who try to import nb-javac from NB 12.x which which breaks pretty much everything). -mbien > > Thanks, > Antonio > > > [1] > > https://maven.apache.org/maven-indexer/indexer-reader/apidocs/org/apac > he/maven/index/reader/IndexReader.html > > > On 17/3/23 11:06, Michael Bien wrote: >> Hello everyone, >> >> I experimented a bit with the maven index extraction process and got >> some pretty good results (I think). >> >> There might be a way to filter the index during extraction without >> noteworthy overhead, which allows the following: >> >> - "sliding window" time filters, e.g drop all documents older than >> 2 years (aka: who uses old libraries?) >> >> - we can drop fields we don't need from the index.
