title: Columnstore Clustered Index - Deadlock issue ( SQL Server )
body: <p>I am working on ingesting data into TABLE A in SQL Server [ with a columnstore clustered index ]. There are 4 parallel threads of "INSERT BULK"
  writing into table, I am getting a deadlock error:</p>
  
  <blockquote>
    <p>Transaction (Process ID) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.</p>
  </blockquote>
  
  <p>After researching, I found out that clustered columnstore index usually get deadlock issues, but could not figure out the resolution. Can you please suggest
  what could be done?</p>
