The alert attribute in the "sequence" of a dashboard in a bi system can be manually populated with fixed values, or you can set the alert range from the data set to enable dynamic alerts. Where the "range" property is manually entered a fixed value should be a percentage (0-1), while the drop-down selection of the binding column value is numeric. The "Color" and "text" can also be taken from the dataset, and when the attribute "sequence-range-text" is

Introduction: Krist óf kolács is a software architect and consultant who recently published an article comparing various nosql databases. Article by agile translation-Tang YuhuaCompile. For more information, see post-Article declaration. Although SQL database is a very useful tool, after 15 years of outstanding performance, the monopoly will be broken. This is only a matter of time: I was forced to use relational databases, but I finally found that I could not meet my needs. However, the differe

Cassandra, as a NOSQL database, selects AP in the CAP principle, which can be used for sex and partition tolerance, and is guaranteed by final consistency in data consistency, using an extension of final consistency--tunable consistency. For any read-write operation, the client application determines the level of conformance for the requested data, Cassandra then responds to the request based on the request

9 can I speed up my large number of writes through bulk submissions? No, using a bulk commit only leads to a deferred spike, replaces it with an asynchronous insert, or uses a true "bulk load"Batch update for the same partition key is an exception, as long as a batch size is maintained within a reasonable range, there is still good, but remember not to blindly use the bulk. 10. In Red Hat Enterprise Edition (RHEL), nodes cannot be added to the cluster. Check to see if the SELinux is turned on a

as an application developer, database applications are already extensive. You may have used relational data, such as MySQL, PostgreSQL, or you might have used document storage, such as MongoDB, or Key-value databases, such as Redis. Each database has its merits, and perhaps you are considering using a distributed database, such as Cassandra, to solve the work you have on hand.The use of these data products is not to replace the original data products,
