Synapse

Open Telemetry based Tracing for Apache Synapse

Currently, Apache Synapse does not have sophisticated support for modern tracing standardized. Therefore this new feature is intended to implement OpenTelemetery based tracing implementation for apache synapse.


This feature will include request-response training and inbound/outbound tracing at the transport level and the orchestration layer. Further, this also needs a really good investigation on Opentelemetry specification[1] and the Apache synapse transport component [1].


Relevant Skills

  1. JAVA language
  2. Understanding about observability 
  3. Integration and Synapse configuration language.

ShardingSphere

Apache ShardingSphere: Proofread the SQL definitions for ShardingSphere Parser

Apache ShardingSphere

Apache ShardingSphere is a distributed database middleware ecosystem, including 2 independent products, ShardingSphere JDBC and ShardingSphere Proxy presently. They all provide functions of data sharding, distributed transaction, and database orchestration.
Page: https://shardingsphere.apache.org
Github: https://github.com/apache/shardingsphere

Background

ShardingSphere parser engine helps users parse a SQL to get the AST (Abstract Syntax Tree) and visit this tree to get SQLStatement (Java Object). At present, this parser engine can handle SQLs for `MySQL`, `PostgreSQL`, `SQLServer` and `Oracle`, which means we have to understand different database dialect SQLs.
More details: https://shardingsphere.apache.org/document/current/en/features/sharding/principle/parse/

Task

This issue is to proofread the DML(SELECT/UPDATE/DELETE/INSERT) SQL definitions for Oracle. As we have a basic Oracle SQL syntax definitions but do not keep in line with Oracle DOC, we need you to find out the vague SQL grammar definitions and correct them referring to Oracle DOC.

Notice, when you review these DML(SELECT/UPDATE/DELETE/INSERT) SQLs, you will find that these definitions will involve some basic elements of Oracle SQL. No doubt, these elements are included in this task as well.

Relevant Skills

1. Master JAVA language
2. Have a basic understanding of Antlr g4 file
3. Be familiar with Oracle SQLs

Targets files

1. DML SQLs g4 file: https://github.com/apache/shardingsphere/blob/master/shardingsphere-sql-parser/shardingsphere-sql-parser-dialect/shardingsphere-sql-parser-oracle/src/main/antlr4/imports/oracle/DMLStatement.g4

SkyWalking

Apache SkyWalking: Python agent collects and reports PVM metrics to backend

Apache SkyWalking [1] is an application performance monitor (APM) tool for distributed systems, especially designed for microservices, cloud native and container-based (Docker, K8s, Mesos) architectures.

Tracing distributed systems is one of the main features of SkyWalking, with those traces, it can analyze some service metrics such as CPM, success rate, error rate, apdex, etc. SkyWalking also supports receiving metrics from the agent side directly.

In this task, we expect the Python agent to report its Python Virtual Machine (PVM) metrics, including (but not limited to, whatever metrics useful are also acceptable) CPU usage (%), memory used (MB), (active) thread/coroutine counts, garbage collection count, etc.

To complete this task, you must be comfortable with Python and gRPC, otherwise you'll have a hard time coming up to speed.

Apache SkyWalking: Python agent supports profiling

Apache SkyWalking [1] is an application performance monitor (APM) tool for distributed systems, especially designed for microservices, cloud native and container-based (Docker, K8s, Mesos) architectures.

SkyWalking is based on agent to instrument (automatically) monitored services, for now, we have many agents for different languages, Python agent [2] is one of them, which supports automatic instrumentations.

The goal of this project is to extend the agent's features by supporting profiling [3] a function's invocation stack, help the users to analyze which method costs the most major time in a cross-services call.

To complete this task, you must be comfortable with Python, have some knowledge of tracing system, otherwise you'll have a hard time coming up to speed..

APISIX

Apache APISIX: Support Nacos in a native way

Apache APISIX is a dynamic, real-time, high-performance cloud-native API gateway, based on the Nginx library and etcd.

Page: https://apisix.apache.org
Github: https://github.com/apache/apisix

Background

To get the upstream information dynamically, APISIX need to be integrated with other service discovery systems. Currently we already support Eureka, and many people hope we can support Nacos too.

Nacos is a widely adopted service discovery system: https://nacos.io/en-us/index.html

Previously we try to support Nacos via DNS. Nacos provides a CoreDNS plugin to expose the information via DNS: https://github.com/nacos-group/nacos-coredns-plugin

However, this plugin seems to be unmaintained.

Therefore, it would be good if we can support Nacos natively via its API, which is expected to be maintained.


Task

Integrate Nacos with APISIX via Nacos's HTTP API.


Relevant Skills

1. Master Lua language and HTTP protocol
2. Have a basic understanding of APISIX / Nacos


Targets files

1. https://github.com/apache/apisix/tree/master/apisix/discovery

Apache APISIX Dashboard: Enhancement plugin orchestration

The Apache APISIX Dashboard is designed to make it as easy as possible for users to operate Apache APISIX through a frontend interface.

The Dashboard is the control plane and performs all parameter checks; Apache APISIX mixes data and control planes and will evolve to a pure data plane.

This project includes manager-api, which will gradually replace admin-api in Apache APISIX.

Background

The plugin orchestration feature allows users to define the order of plugins to meet their scenarios. At present, we have implemented the plugin scheduling feature, but there are still many points to be optimized.

Task

1. develop a new plugin, conditional judgment card style.

2. Add arrows for connecting lines.

3. Limit plugin orchestration operations. For example, only one connection line is allowed between points.

Relevant Skills

1. Basic use of HTML, CSS, and JavaScript.

2. Basic use of  React Framework.

Apache APISIX: Enhanced verification for APISIX ingress controller

Apache APISIX

Apache APISIX is a dynamic, real-time, high-performance API gateway, based on the Nginx library and etcd.

APISIX provides rich traffic management features such as load balancing, dynamic upstream, canary release, circuit breaking, authentication, observability, and more.

You can use Apache APISIX to handle traditional north-south traffic, as well as east-west traffic between services. It can also be used as a k8s ingress controller.

Background

We can use APISIX as kubernetes ingress.Use CRD (Custom Resource Definition) on kubernetes to define APISIX objects, such as route/service/upstream/plugins.

We have done basic structural verification of CRD, but we still need more verification. For example, plug-in schema verification, dependency verification between APISIX objects, rule conflict verification, etc. All these verifications need to be completed before CRD is applied.

Task

1. Implement a validating admission webhook.
2. Support plugins schema verification.
3. Support object dependency verification.

Relevant Skills

1. Golang
2. Be familiar with Apache APISIX's admin API
3. Be familiar with kubernetes

Apache APISIX: support apply certificates from Let’s Encrypt or any other ACMEv2 service

Apache APISIX

Apache APISIX is a dynamic, real-time, high-performance API gateway, based on the Nginx library and etcd.

APISIX provides rich traffic management features such as load balancing, dynamic upstream, canary release, circuit breaking, authentication, observability, and more.

You can use Apache APISIX to handle traditional north-south traffic, as well as east-west traffic between services. It can also be used as a k8s ingress controller.

Background

The data plane of Apache APISIX supports dynamic loading of ssl certificates, but the control plane does not have the support of ACME.
Although users can use other tools to obtain ACME certificates, and then call the admin API to write them into Apache APISIX, this is not convenient for many users.

Task

In the Apache APISIX dashboard (https://github.com/apache/apisix-dashboard) project, add support for ACME, which can automatically obtain and update certificates

Apache APISIX: supports obtaining etcd data information through plugin

Apache APISIX

Apache APISIX is a dynamic, real-time, high-performance API gateway, based on the Nginx library and etcd.

APISIX provides rich traffic management features such as load balancing, dynamic upstream, canary release, circuit breaking, authentication, observability, and more.

You can use Apache APISIX to handle traditional north-south traffic, as well as east-west traffic between services. It can also be used as a k8s ingress controller.

Background
 
When we get the stored data of etcd, we need to manually execute the URI request method to get each piece of data, and we cannot monitor the changed data in etcd. This is not friendly to issues such as obtaining multiple etcd stored data and monitoring etcd data changes. Therefore, we need to design a method to solve this problem.

Related issue: https://github.com/apache/apisix/issues/2453

Task

In the Apache APISIX (https://github.com/apache/apisix) project, implement a plug-in with the following functions:

1.Find route based on URI;
2.Watch etcd to print out the object that has recently changed;
3.Query the corresponding data based on ID (route, service, consumer, etc.).

Relevant Skills

1. Master Lua language;
2. Have a basic understanding of API Gateway or Web server;
3. Be familiar with ETCD.
