Announcing the release of Apache AGE 0.3.0
Posted on 2021-02-08 by Apache AGE
Apache AGE Team has released version 0.3.0 of Apache AGE.
Apache AGE is a PostgreSQL extension that provides graph database functionality. AGE is an acronym for A Graph Extension, and is inspired by Bitnine's fork of PostgreSQL 10, AgensGraph, which is a multi-model database.

- Trigonometric: e, sqrt, exp, log, log10, degrees, radians, pi, sin, cos, tan, asin, acos, atan, & atan2.
- String: replace, split, left, right, substring, rTrim, lTrim, trim, toUpper, toLower, reverse, & toString.
- Numeric: rand, abs, ceil, floor, round, & sign.
Added user defined functions of the form:
- Currently working on aggregate function support.

- min, max, stDev, stDevP, percentileCont, percentileDisc & count.
- avg & sum are added but may need to be reworked.
