A recent Mark Reinhold message announces six new "JEPs proposed to target JDK 14": JEP 345, JEP 361, JEP 363, JEP 364, JEP 365, and JEP 367. Assuming no objections are made by November 7, these JEPs will be targeted to JDK 14 along with previously targeted JEPs JEP 349 ("JFR Event Streaming"), JEP 352 ("Non-Volatile Mapped Byte Buffers"), and JEP 358 (" Helpful NullPointerExceptions"). This post summarizes each of these six JEPs proposed for targeting JDK 14.
JEP 345: NUMA-Aware Memory Allocation for G1
The succinct "Summary" of JEP 345 states, "Improve G1 performance on large machines by implementing NUMA-aware memory allocation." Two important "non-goals" of this JEP indicate that the JEP is only intended to add NUMA (non-uniform memory access) support to the G1 garbage collector and only for Linux. However, the JEP also points out that "the parallel collector, enabled by -XX:+UseParallelGC, has been NUMA-aware for many years."
Candidate JEPs: Records and Sealed Types
Mark Reinhold announced two new closely related candidate JDK Enhancement Proposals (JEPs) on the OpenJDK amber-dev mailing list this week with the posts "New candidate JEP: 359: Records (Preview)" and " New candidate JEP: 360: Sealed Types (Preview)." Both of these candidate JEPs are "preview features" (defined by JEP 12).

JEP 359: Records (Preview)
The JEP 359 "Summary" states, "Enhance the Java programming language with records. Records provide a compact syntax for declaring classes which are transparent holders for shallowly immutable data."
How to Share Your Redis Geek Story at RedisConf ’19
It's that time of year! No, I don't mean the seasons changing. It's RedisConf CfP time!
This is your opportunity to talk about Redis in front of a gathering of fellow geeks. RedisConf '19 will be held April 2-3 at San Francisco's Pier 27. That might seem like a long time from now, but we're already busy putting together a schedule of sessions to ensure that April will be great.
