Noble Paul commented on SOLR-16812:
-----------------------------------
Let's be clear about the objectives of this ticket.
We use JSON to index/query Solr because we do not use java. So we need a more
efficient method to interact with Solr(especially indexing, because we are
write heavy). I wanted to pick up a format that has libraries in as many
languages as possible (Go, python, C# etc)
{quote}What does the CBOR performance look like generally?
{quote}
Here is a [benchmark|https://ugorji.net/blog/benchmarking-serialization-in-go]
from the wild. The point is most of these binary formats are much better than
JSON.
{quote}"films.json" feels a little small to be testing this.
{quote}
It has 1100 docs. How often do we index/fetch more than 1100 docs?
{quote}Can you elaborate at all on why you chose CBOR over other alternatives?
{quote}
I have done benchmarks and it concurs with the numbers we see in the wild. Avro
is not considered because there is no jackson support and I didn't find a good
Go support too.
{quote}if we introduce a new binary format, then it should come with a plan to
deprecate or replace javabin.
{quote}
I wish to see it happening. javabin must go(if possible). We need to do a lot
of refactoring on our Solr/SolrJ code before it is possible. It's a non-trivial
task.
