How to increase array length? I have to store move then 20K records in array
What do you mean? you give limited info.
If you you mean you only see 1000 in debug sidecar, that is because the sidebar truncates for performance reasons the array is still there in memory.
e.g array size 25000

If you go to http://ip_of_node-red:1880/debug you will see the full array.
I have to store 10000-50000 items in array but seems like there is limit of adding element in that number? so is there any setting to increase this number
What makes you think there is a limit?
What do you mean by limit? Javascript arrays can contain up to 2^32 elements, so that should be more than enough. 
Here is some relevant info on the basics of arrays in Javascript:
Furthermore, JS is rather lenient regarding array size, you can push new elements or set indexes without explicitly increasing the size. Here's more info on the length property.
