Splitting & Duplicating Data

💡 Shard, EK, "KITAAB, KE, CHAPTERS" mein, BAANTNE, jaisa, hai, (data, split), aur, Replica, HAR, CHAPTER, ki, "PHOTOCOPY" jaisi, hai, (backup, copy, dusre, server, par).

Shard, EK, Collection, ka, EK, HISSA, hai — DATA, ko, MULTIPLE, shards, mein, SPLIT, karne, se, INDEXING, aur, SEARCH, LOAD, MULTIPLE, servers, mein, SPREAD, ho, jaata hai.

Replica, EK, shard, ki, EK, COPY, hai, EK, DIFFERENT, node, PAR — agar, EK, replica, ka, node, CRASH, ho, jaaye, TO, DOOSRI, replicas, TRAFFIC, HANDLE, karti, RAHTI, HAIN, koi, DOWNTIME, nahi.

# 2 shards, har shard ki 2 replicas = 4 total nodes
bin/solr create -c mycollection -shards 2 -replicationFactor 2
