Houston Putman commented on SOLR-14013:
---------------------------------------
I've created a patch that adds in [~noble.paul] 's test and fix (without the
large file), and reverts the conversion for indexing and deserializing
responses. I think I incorporated all of the places that you mentioned
[[email protected]]. The only issue in the tests was in the langid contrib
module, which was reverting a later-made fix.
Probably too close of a call to get it into 8.4. What do y'all think of
backporting this to 7.7.x, since it is such a serious regression?
The solr/lucene tests pass on 8x and master. I've used [~rrockenbaugh]'s
testing method mentioned above, for all branches that I could think would be
relevant. The results are below:
*patch (8.x)*
Ingest - 1.2 seconds
Sharded Query - 0.4 seconds
Non-Distrib Javabin Query - 0.17 seconds
Non-Distrib JSON Query - 0.13 seconds
*patch (master)*
Ingest - .87 seconds
Sharded Query - .3 seconds
Non-Distrib Javabin Query - 0.06 seconds
Non-Distrib JSON Query - 0.08 seconds
*7.6*
Ingest - 1.6 seconds
Sharded Query - 0.3 seconds
Non-Distrib Javabin Query - 0.12 seconds
Non-Distrib JSON Query - 0.15 seconds
*7.x*
Ingest - 1.3 seconds
Sharded Query - 36 seconds
Non-Distrib Javabin Query - 30 seconds
Non-Distrib JSON Query - 0.3 seconds
*8.x*
Ingest - 1.18 seconds
Sharded Query - 21 seconds
Non-Distrib Javabin Query - 20 seconds
Non-Distrib JSON Query - 0.07 seconds
*master*
Ingest - 2.6 seconds
Sharded Query - 35 seconds
Non-Distrib Javabin Query - 35 seconds
Non-Distrib JSON Query - .16 seconds
