Matrixdb V4.5.0 was launched with a new mars2 storage engine!

After nearly 4 Months of hard work , all-new MatrixDB v4.5.0  Official release .

this  MatrixDB v4.5.0 Welcome many major updates , Include ： Launch a new storage engine MARS2, Add query information statistics component 、 New support sliding window And MatrixDB on Kubernetes Deployment and other functional features ,Mxbench 、MatrixGate Upgrade both , And fixed some problems encountered in production practice .MatrixDB In terms of functionality and stability , Continuous and stable improvement .

01  New launch MARS2 Storage engine

MARS2 Storage engine in  MARS1 Develop on the basis of , It's solved  MARS1 The problem of guiding tables . In order to achieve the effect of dynamic sorting ,MARS2 The internal of storage draws lessons from LSM TREE The concept of , Implemented by a two-tier class LSM structure . Classes at each level LSM The structure consists of two sorting units （ Logical tape set or tapesets） form , Each sorting unit consists of several logical tapes （tape） form . Finally, dynamic sorting is realized , The effect of dynamic compression .

02 Add query statistics mxstat

Add query statistics component （mxstat）, By aggregating the same queries , To count query execution times 、 Time consuming 、 Resource occupancy information, etc . Through this function , Users can perform on the database SQL Statistics and monitoring , And better understand the resource consumption of various queries , Then we can locate and analyze slow queries .

03  Support sliding window flow calculation

Sliding window is a common function of flow computing scene . In the scenario of stream computing data , Through the sliding window, the data in the recent period of time can be continuously analyzed and calculated . Unlike scrolling windows, non overlapping , Time windows of sliding windows can be overlapped . Sliding windows are usually used in conjunction with monitoring alarms , When the data in the latest period of time meets the preset conditions , The data server will send an alarm message to the client .

MatrixDB v4.5.0 Add sliding window flow calculation , It can realize real-time analysis and monitoring of convection data , And support the subscription and publication of monitoring data , When the data is abnormal, you can get the alarm message through subscription .

04 Mxbench Optimize upgrade , Support flexible configuration

Mxbench yes MatrixDB Pressure test tool for data loading and query , According to the number of devices given by the user 、 Time range 、 The indicator quantity configuration can quickly generate random data , Automatically create data tables , Load and query data serially or concurrently .

this   Mxbench  It's upgraded , Support users to flexibly configure indicator types 、 Acquisition frequency 、 Null rate 、 Randomness, etc , Users can also specify the number of threads to query 、 Custom query statements, etc .Mxbench  You can run... From the command line , You can also run through the configuration file .

05 MatrixGate Upgrade again

MatrixGate abbreviation mxgate, yes MatrixDB Built in high-performance data loading tool . This upgrade ,mxgate newly added ：

• Support for CSV Any column of the file , perhaps JSON Any of the files Value, Perform timestamp type conversion （timestamp）, The conversion accuracy supports second level , millisecond , Microsecond and nanosecond ;

• newly added Watch function , Can be in mxgate In operation , see mxgate Real time indicators and historical indicators of data loading , The data loading performance is clear at a glance , At the same time, it also greatly reduces the difficulty of troubleshooting problems related to data loading ;

• Upsert Support boolean data type .

06  Support MatrixDB on K8s Deploy

MatrixDB v4.5.0 New support through Operator Pattern , Realize in Kubernetes Rapid deployment on a cluster MatrixDB The function of . Users can use the Kubernetes Install in cluster matrixdb-operator The way , Implement multiple MatrixDB Rapid deployment of clusters .
