Big Data pipeline challenges

Reliability of Kafka

v 3 Brokers

v 3 Zookeeper instances

v default.replication.factor=2

v Mainly with Default Configurations

v 5 Brokers

v 5 Zookeeper instances

v unclean.leader.election.enable=false

v min.insync.replicas=2

BEFORE AFTER

Big Data pipeline challenges

Spark Streaming Checkpointing

v Spark checkpointing

v All RDD serialized and stored at HDFS

v Custom kafka checkpointing

(Only latest offset stored at kafka)

BEFORE AFTER

Big Data pipeline challenges

Elasticsearch indexing big data

v Default mapping

v index.refresh_interval = 1s

v Indices.memory_index_buffer_size= 10%

v Custom mapping with disabled norms

v Mapping using simple analyzer

v index.refresh_interval = 30s

v Indices.memory_index_buffer_size= 30%

v spark.streaming.kafka.maxRatePerPartition=10000
