zipkin.storage.cassandra

Class CassandraStorage

java.lang.Object

zipkin.storage.guava.GuavaStorageComponent

zipkin.storage.guava.LazyGuavaStorageComponent<CassandraSpanStore,zipkin.storage.cassandra.CassandraSpanConsumer>

zipkin.storage.cassandra.CassandraStorage

All Implemented Interfaces:

Closeable, AutoCloseable, Component, StorageComponent

public final class CassandraStorage
extends LazyGuavaStorageComponent<CassandraSpanStore,zipkin.storage.cassandra.CassandraSpanConsumer>

CQL3 implementation of zipkin storage.

Queries are logged to the category "com.datastax.driver.core.QueryLogger" when debug or trace is enabled via SLF4J. Trace level includes bound values.

Redundant requests to store service or span names are ignored for an hour to reduce load. This feature is implemented by DeduplicatingExecutor.

Schema is installed by default from "/cassandra-schema-cql3.txt"
