------------------------------------------
Summary: Performance issue with big message deserialization using
php extension
Key: THRIFT-3839
URL: https://issues.apache.org/jira/browse/THRIFT-3839
Project: Thrift
Issue Type: Improvement
Components: PHP - Library
Affects Versions: 0.9.3, 1.0
Reporter: Myroslav Kosinskyi
Fix For: 1.0
I have found performance issue when tried to deserialize big thrift binary
message with enabled thrift_protocol php extension.
Messsage size was 10 mb and it took about 30 seconds to deserialize it.
When i have done debug of php extension and php library i have found that issue
is because small read buffer is used in TBufferedTransport and i cannot change
it from TBinarySerializer::deserialize method.
So i have added parameter $buffer_size to function thrift_protocol_read_binary
from php extension.
And also this parameter i have added to method TBinarySerializer::deserialize
from php library.
And i extended class Thrift\Transport\TMemoryBuffer by method putBack, so this
class will be used for desearilization without TBufferedTransport warapper.
