Re: Apache Drill - Read Java Objects

Based on how I understand your questions, you have serialized java objects with a field you want to query. How are the java objects serialized? -- Jacques Nadeau CTO and Co-Founder, Dremio On Thu, Feb 18, 2016 at 6:48 PM, jorge gonzalez wrote: > Hello, > The company I currently work for stores
