Hello all.

I have a splayed table with approximately 400m rows and I can’t work with this table after mapping(limitation by 32bit version of kdb).

Using ‘get’ at query got same error.

Does it any way to work with tables without loading it at memory?

At least simply export this table in csv.

PS this table was compressed.
