If I were to add this to the Solr wiki as potential options under
postingsFormat, would it be correct?
“Appending” works with append-only filesystems (such as Hadoop DFS)
“Memory” writes the entire terms+postings as an FST read into RAM
“Pulsing” inlines the postings for low-frequency terms into the term
dictionary
“SimpleText” writes all files in plain-text for easy debugging/transparency
“Bloom” uses a bloom filter to sometimes avoid disk seeks when looking
up terms
“Direct” holds all postings as simple byte[] and int[] for very fast
performance at the cost of very high RAM consumption
“Block” use a new index layout and compression scheme for improved
performance
Thanks,
Shawn
