Does es`current compression algorithm suppot only lz4 and deflate?Whether it supports other open source algorithms,or custom algorithms?
I do believe those are the only two options.
Is there only two algorithms in Lucene, so es can only use lz4 and deflecte？
It is what Elasticsearch exposes. Why would you need another algorithm? Given that these only apply when compressing the document source, using an even more compressing algorithm might not save as much space as you think but still impact performance.
yes,just try another algorithm to improve performance.
What performance problems are you facing? How would a different compression option help address this? I suspect there could be other optimisations that would have much more impact.
How do I change the File system storage types?
I tested the scroll, the hot spot function is compression, so I want to try another compression algorithm. Is there a replacement method here?
Not that I know of.
