Mined Opinions For API: cassandra

This tab contains all the opinions collected from Stack Overflow about the API. The other tabs present summaries of the opinions using different algorithms.
  • Thank you so much man you are always so thorough in your answers and explanations.. details
  • My use cases : I use jackson as serialization when I need to save blobs to storage systems (Redis, Cassandra, Mongo, ... sometime mysql too).. details
  • In Cassandra, writes are much more efficient than reads so it is beneficial to avoid reads before writes if possible.. details
  • In conclusion, there could be significant performance advantages to using separate columns if you have to update your data or if you only want to read parts at once.. details
  • In Cassandra, writes are much more efficient than reads so it is beneficial to avoid reads before writes if possible.. details
  • I am actually tempted to do this to all of my data.. details
  • Cassandra is adding support for JSON-like maps, lists, and sets in 1.2: URL_https://issues.apache.org/jira/browse/CASSANDRA-3647 [ URL_https://issues.apache.org/jira/browse/CASSANDRA-3647 ] .. details

  • Thanks in advance.. details
  • My question is, is there a Java API that persists such big objects in Cassandra?After searching, MongoDB seems to perform this very well, but I want to know if it can be made in Cassandra via some API.. details
  • Why would the database care abount the contents of the string.. details
  • Given that you have the key-val pairs grouped in JSON, they presumably belong to the same entity and are related, so this is unlikely to be useful, but I mention it for completeness.. details
  • This method would let you retrieve individual values, and use secondary indexes to retrieve rows with particular values.. details
  • You could split up the JSON before storage, so that key1, key2 are column names and val1, val2 are the corresponding column values.. details
  • Anybody know which is the easy way to insert a json string in cassandra.Suppose I have a json string like this: {'key1':'val1','key2':'val2'} In MongoDB we can insert directly a json string like dbobj.insert(jsonstring);So is there any way to do like this in Cassandra?. details
  • Suppose you have some complex JSON like: CODESNIPPET_JAVA1 .. details
