original_language_ididentifier of the initial language on the movie in case it truly is dubbed into a new language.
It really is made and optimized for OLTP purposes on relational structured info, however its shared-nothing framework also supports OLAP programs.
OceanBase supports each vertical and horizontal parallelism, which will increase throughput and lessens latency.
OceanBase adopts regular non-blocking checkpoint mechanism. Their staff is currently engaged on the development of fuzzy non-blocking checkpoint system carried out in LSM tree structure. They want to launch that in future Variation.
OceanBase employs column compression. It implements a number of encoding algorithms and it immediately chooses the most suitable one particular for every column. It adopts column compression to leverage data similarity, for example exact same facts sort, very same benefit assortment, and many others.
@TomJMuthirenthi I do not Consider Explain suits into any of the two. It just returns It is very own representation of how a Desk/DB is structured. You 跨平台数据库对象迁移 can reach a similar point with e.g. Produce although not as "human-readable"
OceanBase works DDL迁移/转换 by using column compression. It implements quite a few encoding algorithms and it routinely chooses the most suitable one particular for each column. It adopts column compression to leverage details similarity, for example very same facts type, identical value variety, etc.
The momentary desk comprising The brand new clustered index is renamed While using the title of the initial desk, and the initial desk is dropped from your database.
For index selection, as OceanBase splits desk into partitions, it supports regional indexing for local partitions and worldwide indexing for international partitions.
Since the table structure is carefully tied to the primary critical, redefining the first key nonetheless involves copying the info.
Enhanced responsiveness and availability in fast paced output environments, in which building a desk unavailable for minutes or hrs will not be functional.
When you choose the info in several formats, you modify the presentation using表达式优化 of the info for that query, instead of the information by itself.
OceanBase utilizes column compression. It implements quite a few encoding algorithms and it quickly chooses the most fitted one particular for each column. It adopts column compression to leverage information similarity, for example identical info variety, exact same price vary, etc.
OceanBase also supports secondary index. It combines index keys and table Key essential for secondary index.
