How Can I Configure fillfactor

fillfactor is a parameter used to describe the page filling rate and is directly related to the number and size of tuples that can be stored on a page and the physical space of a table. The default page filling rate of Ustore tables is 92%. The reserved 8% space is used for page update and TD list expansion. For details about how to configure and modify fillfactor, see "SQL Reference > SQL Syntax > CREATE TABLE" in Developer Guide.

You can configure fillfactor after analyzing services. If only query or fixed-length update operations are performed after table data is imported, you can increase the page filling rate to 100%. If a large number of fixed-length updates are performed after data is imported, you are advised to retain or decrease the page filling rate to reduce performance loss caused by cross-page update.
