--------------------------------------
Summary: Ruby: Performance improvements for parsing
Key: AVRO-1260
URL: https://issues.apache.org/jira/browse/AVRO-1260
Project: Avro
Issue Type: Improvement
Components: ruby
Affects Versions: 1.7.3
Reporter: Martin Kleppmann
I've made a few performance improvements to the Ruby Avro decoder. In my tests
(decoding a complex record with many fields and nested records), I saw a 40%
speedup on MRI 1.8.7 and a 20% speedup on MRI 1.9.3. The improved code also
makes about half as many object allocations as before.
Main changes are:
* Using symbols instead of strings for the various schema types (there was
actually a FIXME in the code for this, now fixed)
* Added a few memoizations to avoid unnecessarily recomputing values
I've tried to keep the API unchanged — {{Avro::Schema#type}} still returns a
string, as users may be relying on the type ({{Avro::Schema#type_sym}} has the
symbolized version). So I don't think this patch introduces any compatibility
problems (as long as apps aren't relying on internals of the Avro library).
