To be fair, I didn’t fully understand the services or microservices at that point - that made me skeptical of its use for something like data fetching. I brushed it away - not realizing the problems I was going to face in the next year. Because the database access was finely ingrained into the rest of the codebase, it was not possible to optimize or load balance properly.Ībout a year ago, I was asked if we should convert that library to a service.

Similarly, different types of securities (Future, Option, Stock etc.) were stored in different locations. Intraday market data was stored differently in a cassandra cluster, while the daily/monthly data was in a MySQL database. I was writing a bunch of ML training scripts as well as several production scripts.ĭata was spread across multiple tables and multiple datastores. gRPC vs Thrift vs RP圜 comparison matrix.This means that it is possible to define a service and change the protocol and transport without recompiling the code.RPC Frameworks: gRPC vs Thrift vs RP圜 for python The protocol and transport layer are part of the runtime library. Processor : Reads data from the input, processes the data throught the Handler specified by the user and then writes the data to the output.Transport layer : provides is responsible for IPC communication.Protocol layer : provides serialization and de-serialization support.

UserLoginRequest user=new userLoginRequest() TProtocol protocol = new TBinaryProtocol(transport) Transport = new TSocket("localhost", 7914) thrift file with which we define the UserLogin RPC is as follows The Thrift compiler generates fully functional client and server stubs that implement the interface.Ī service consists of a set of named functions, each with a list of parameters and a return type.Ī simple. Definition of a service is semantically equivalent to defining an interface (or a pure virtual abstract class) in object oriented programming.
THRIFT IDL GENERATOR
A Thrift IDL file is processed by the Thrift code generator to produce code for the various target languages to support the defined structs and services in the IDL file. The Thrift interface definition language (IDL) allows for the definition of Thrift Types. The Thrift compiler will read this file and generate source code to be used from the servers and clients you will write.

thrift file you can define the services that your server will implement and that they will be called by any clients.
