Iā€™m wondering if KDB has WORM (Write once and read many) function. We are trying to see if KDB can be used for some reporting purposes. We would like to have some table read/write and some table read only after write. Is that possible?
I want to create a KDB table with an array: - for a regular one, I would have t:([]time:`time$();price:`float$()); for each time, there is only price - I want to have a table with a price array for each time. should I create it using t:([]time:`time$...
when I query HDB, it is always faster using date>$date$? $date$ could be .z.d-10000, which is much larger than my earliest date in KDB.
1. how to push data to KDB using qpython? 2. is there any script to push data to HDB? assume I have lots of dated trade data, how can I push data to kdb by setting trade date as the data of HDB. thanks
