Replica Set Primary Member :<\/h4>\n

\n
• In replica set Primary is the only member that receives write operations.<\/li>\n
• In replica set secondary member is to log and apply the operations to their data.<\/li>\n
• MongoDB applies write operations and records the operation on primary\u2019s oplog.<\/li>\n
• The primary member accepts all write operations in the following three-members replica set.<\/li>\n
• The secondary member replicates the primary\u2019s oplog to apply their data sets.<\/li>\n
• In replica sets all members can accept to read captions.<\/li>\n
• In replica sets, read preference describes how MongoDB clients route read operations to the members.<\/li>\n
• An election determines the new primary, If the current primary becomes unavailable.<\/li>\n
• Replica setsuse elections to determine which set member will become\u00a0primary.<\/li>\n
• The primary becomes unavailable, in the following 3-member replica set.<\/li>\n
• This triggers an election which selects one of the remaining secondaries as the new primary.<\/li>\n<\/ul>\n

  Replica set Secondary Member:<\/h4>\n

  \n
  • In replica sets secondary maintains a copy of the\u00a0primary’s data set.<\/li>\n
  • A secondary applies operations from the primary’s\u00a0oplog to its own data set in an asynchronous process, to replicate data.<\/li>\n
  • A replica set can have one or more secondaries.<\/li>\n
  • In replica sets, the following three-member has two secondary members.<\/li>\n
  • The secondaries replicate the primary’s oplog and apply the operations to their data sets.<\/li>\n
  • In replica set client cannot write data, but they can read data from secondary members.<\/li>\n
  • A secondary can become a primary.<\/li>\n
  • The replica set holds an\u00a0election to choose which of the secondaries becomes the new primary, If the current primary becomes unavailable.<\/li>\n<\/ul>\n
