Ideas List

id	project title	skills required	possible mentors	expected size of project	difficult rating	detailed description
1	Adjustment of the number of data replicas	datanode/master	Leon Chang	175	intermediate	Currently support 3 copies instead of 2 copies, and 2 copies are reduced to single copies.The current demand is: single copy can be upgraded to two copies, and two copies can be upgraded to 3 copies.
2	Modification and write optimization	client	Whale Tang	90	easy	When a small file extent is overwritten and modified, the extent is re-created. This part is not necessary. You can consider modifying it directly to improve efficiency.
3	Network communication protocol merging	metanode/datanode	Victor1319	90	intermediate	File deletion is asynchronous, and the actual executor is the metadata system. The deletion from mp to dp is currently a single request. In fact, merging optimization can be done to solve the pressure and efficiency problems of large-scale deletion.
4	Statistical service	metanode/datanode	Leon Chang	90	easy	Currently provide statistics by the master service. We can also consider supporting metanode and datanode.
5	Panic mp and dp try to reload	metanode/datanode	Leon Chang	90	intermediate	Currently some panics are caused by communication with the master and other scenarios. For better service, you can consider following up on the problem classification, such as abnormal communication with the master, or abnormal disk reading, and you can consider reloading
6	Hierarchical flow control	metanode/master	Whale Tang	350	difficult	Build Hierarchical flow control in replica storage subsystem, data reading and writing > data repair > data migration > data balancing > data migration across clusters > data self-checking
7	MP node memory automatic balancing	metanode/master	Victor1319	175	intermediate	Automatically triggers metadata partition migration within the cluster to ensure balanced usage
8	Atomic support for mp migration	metanode/master	AmazingChi	350	difficult	The migration process is managed by the master and metanode participates. Because it is a distributed system, mp migration involves multi-step operations. Abnormalities in some steps will cause some to take effect and some to fail. As a result, the system has no control over the metadata copy. Inconsistency occurs
