Re: Size of an Object

You can serialize the object and check the length of the byte array: byte[] arr = ignite.configuration().getMarshaller().marshal(new Person(10L, "first", "last")); System.out.println(arr.length); Then refer to this page to calculate the total cache capacit: https://apacheignite.readme.io/docs/cap

Presently the community plans to release 2.0 in Feb. If it’s shifted there is a chance that 1.9 will be released instead and earlier. However, someone still needs to take care about this ticket. — Denis > On Jan 6, 2017, at 1:36 PM, zshamrock wrote: > > Hi, Denis. > Thank you for creating the

Hi, Denis. Thank you for creating the issue. I will keep an eye on it. If nobody picks it up, and I find free time, then I will pick up it myself. When do you plan to release 1.9.0 version (is there a roadmap)? (as I've not seen you've been releasing minor versions like 1.8.1 including some of the
