TLDB:high performance distributed database [中文]

  • Tldb has the features of high availability, high performance, no data loss, excellent horizontal expansion ability and so on。
  • With its own web management platform, cluster status monitoring, parameter modification, data management operations can be completed in the management platform
  • Support MQ. The implementation mechanism and network characteristics of tldb itself have all the features of MQ from the bottom
  • Easy to maintain. Cluster status and node status are automatically adjusted, no network islanding occurs.
  • When the disk of a node is fully written or incorrectly written, the node enters the proxy mode, which does not affect the operation of the client
  • Tldb supports basic operations such as creating tables, indexes, and table fields through client operations.
  • Tldb supports a large number of concurrent client operations, and can well support big data writing and reading.

TLDB:application scenes

  • Suitable for scenarios where the business query logic is not complicated, such as orders, logistics,IM message bodies, and wallets
  • Suitable for data warehouse
  • Suitable for scenarios with a large number of MQ requirements
  • Suitable for scenarios that require fast data entry and reading

Problems that TLDB can solve

  • Solve the problem of concurrent read and write performance of large amounts of data
  • Solve the problem of large amounts of MQ information subscription publishing
  • Solves problems that require rapid cluster horizontal scaling
  • Solves problems where data needs to be checked back at different points in time

TLDB:technical feature

  • tldb logs record data change trajectories and supports data restoration to any point in time
  • The data engine uses leveldb currently;leveldb has efficient read and write performance and stability; In a specific configuration environment, it even has the advantage of millions of data seconds into the database
  • Supports data compression, greatly optimizing storage space
  • tldb uses the consensus mechanism, two-stage commit confirmation, and binlog to ensure data consistency among all nodes
  • The node proxy mechanism ensures that abnormal nodes do not affect data operations
  • The cluster uses the consensus algorithm to hash data for storage, and the number of storage node can be specified by parameters.
  • Compression protocol, aggregation protocol sending and receiving, object pool optimization, tldb has excellent performance, and supports a large number of client connection concurrent operations.
  • tldb supports MQ from the design of the architecture, and cluster MQ data is consistent without loss
  • tldb MQ solves the problems of MQ message loss, repeated consumption, and message backlog

TLDB:characteristics of data

  • Support field index
  • Field indexing is supported and the data table automatically generates a 64-bit self-growing uniquely identified ID key
  • MQ data is essentially tldb data and also automatically generates ID keys

Advantages and disadvantages of TLDB compared to other distributed databases

  • tldb is easy to use, requires no installation, and has almost no maintenance costs
  • tldb cluster environment is simple to use and no different from the single-node environment
  • tldb data is not lost, and it is automatically split and compressed for backup
  • Backup, compression, and synchronization of tldb data are automatically completed. To restore imported data, you only need to import data files on the management platform
  • tldb search function is relatively weak and does not support joint indexes
  • tldb data types are not as rich as relational databases

TLDB Startup Overview

Take linux as an example

Single-machine startup

  • ./tldb -clus=0 When the startup parameter clus is 0, tldb is enabled in single-node mode (cluster mode by default)
  • ./tldb -clus=0 -mq=:5000 -admin=:4000 -dir=_data -cli=:7000Binding mq port (-mq), management background port (-admin), database client port (-cli), and data file address (-dir)

Cluster startup: The following uses starting three nodes as an example

  • ./tldb -cs=:6001 -mq=:5001 -admin=:4001 -dir=_data1 -cli=:7001
  • ./tldb -cs=:6002 -mq=:5002 -admin=:4002 -dir=_data2 -cli=:7002
  • ./tldb -cs=:6003 -mq=:5003 -admin=:4003 -dir=_data3 -cli=:7003

Cluster node connection

  • login in Management platform of any node, from cluster env -> Add cluster nodes Enter the cluster service addresses of other nodes:e.g. :6003 or
  • After adding other node addresses in the Management platform of a node, all the cluster nodes will automatically synchronize information with each other (there is no need to add cluster nodes to each other repeatedly).

parameter description:

  • -cs Cluster node interconnection address
  • -mq MQ service address of the node
  • -admin Management platform service address of a node
  • -dir Data file address of the node
  • -cli Client connection address of the node

format of service address:

  • There are four parameters that can be bound the service address: -cs, -mq, -admin, and -cli
  • The address format is: domain(or IP)+":"+ port, where the domain(or IP) is the domain(or IP) bound to access, that is, if the domain(or IP) is bound, other domain(or IP) cannot be accessed. For example,
  • You can use ":"+port without binding the domain(or IP), for example, -admin=:4000

other main parameters description:

  • -clitls=1 Enable the TLS service for client. The default is 0, which means disabled
  • -mqtls=1 Enable the TLS service for MQ. The default is 0, which means disabled
  • -admintls=1 Enable the TLS service for Management platform. The default is 0, which means disabled
  • For other parameters, see Management Background or

Other operating systems: windows, macos, freebsd, solaris use tldb

The above operating systems use tldb no different from linux, for example:

The following uses windows single-node operation as an example:

tldb.exe  -clus=0 -mq=:5000 -admin=:4000 -dir=_data -cli=:7000
