Data Pipeline
Series of processes that move and transform data between systems for analysis, storage, or further processing.
Root Causes
HTTP Path
RPC Method
Database Table
HTTP Path
Congested
The HTTP path is experiencing congestion, resulting in high latency for clients. This suggests that the system is unable to handle the current load efficiently, causing delays in response times.
Congestion often occurs when the service receives more requests than it can handle within its capacity, leading to bottlenecks in processing. This may be due to insufficient resources (for example, CPU, memory, or bandwidth), unoptimized code, or a surge in traffic (for example, due to a sudden increase in demand or DDoS attack).
Malfunction
The HTTP path is experiencing a high rate of errors, causing disruptions for clients. This can lead to degraded performance, failed requests, or complete service unavailability, significantly affecting the user experience.
RPC Method
Congested
The RPC method is experiencing congestion, resulting in high latency for clients. This suggests that the system is unable to handle the current load efficiently, causing delays in response times.

Malfunction
The RPC Method is experiencing a high rate of errors, causing disruptions for clients. This can lead to degraded performance, failed requests, or complete service unavailability, significantly affecting the user experience.
Database Table
Malfunction
The database table is experiencing performance degradation or errors, causing disruptions for client applications. This results in slow query response times, potential errors, and degraded service performance for systems that depend on this table.
Excessive Lock
The database table is experiencing an abnormally high rate of exclusive locks, preventing multiple transactions from accessing the table simultaneously. This creates a bottleneck that significantly degrades performance for all client applications depending on this table.
DDL Excessive Lock
The database table is experiencing an unusually high rate of Data Dictionary Lock(DDL), which block both read and write operations during schema modifications. This significantly impacts all client applications, causing service disruptions and performance degradation.
