Indexing is a useful tool that provides more types of queries on your tables. In principle, columns we wish to be queryable should be declared when the table is created, as part of a table’s primary key. Secondary Indexing is a neat way of making other columns queryable, but it comes with a cost of additional storage space and processing power to maintain the secondary index data coherent with the primary index information.

Racing the Red Queen

“Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!” — The Red Queen to Alice, Alice Through the Looking Glass In the world of Big Data, if you are not constantly evolving you are already falling behind.

We will discuss the differences between the old and new formats, and demonstrate use cases in which the new format has significant advantages, and others where the advantages are much smaller. This is truly a situation of “Your Mileage May Vary.” For example, in one test result below, we were able to show a 53% reduction in table size. Other use […]

Also note that schemas are still enforced for all operations — one cannot just insert random JSON documents into a table. The new API is simply a convenient way of working with JSON without having to convert everything back and forth client-side. JSON support consists of CQL statements and functions, described here, one by one, with examples. You can use the following code […]
