by range (when need to query by range). Range-based sharding involves dividing data into contiguous ranges determined by the shard key values. In this model, documents with “close” shard key values are likely to be in the same chunk or shard. This allows for efficient queries where reads...

Relying on database constraints to ensure consistency across functional groups creates a coupling of the schema to a database deployment strategy. For constraints to be applied, the tables must reside on a single database server, precluding horizontal scaling as transaction rates grow. In many cases...
Through the sql that you execute, shardingsphere cannot determine whether did column has changed, so you need to specify value of did in where condition. By comparing did value in set clause with did value in where condition, shardingsphere can determine whether the data node has changed due ...
Data is uniformly distributed on all the nodes in the cluster by using a sharding algorithm applied to the primary key. The connector contains a connection pool for each node in the cluster. The connection pool has three responsibilities:
Sharding-JDBC Version: 4.0.0-RC2 org.apache.shardingsphere.core.execute.sql.execute.result.QueryResultUtil convert column data to crossponding java Object by ResultSetMetaData, but the target data type may be a compatible java type. Suggestion: ...

Zero Management: Installation and cluster setup can be done in seconds. Data partitioning and sharding are executed automatically. TDengine’s running status can be monitored via Grafana or other DevOps tools. Zero Learning Cost: With SQL as the query language, support for ubiquitous tools like Py...
