Method Detail

keyspace

public CassandraStorage.Builder keyspace(String keyspace)

Keyspace to store span and index data. Defaults to "zipkin"

contactPoints

public CassandraStorage.Builder contactPoints(String contactPoints)

Comma separated list of hosts / IPs part of Cassandra cluster. Defaults to localhost

localDc

public CassandraStorage.Builder localDc(@Nullable
                                        String localDc)

Name of the datacenter that will be considered "local" for latency load balancing. When unset, load-balancing is round-robin.

maxConnections

public CassandraStorage.Builder maxConnections(int maxConnections)

Max pooled connections per datacenter-local host. Defaults to 8

ensureSchema

public CassandraStorage.Builder ensureSchema(boolean ensureSchema)

Ensures that schema exists, if enabled tries to execute script io.zipkin:zipkin-cassandra-core/cassandra-schema-cql3.txt. Defaults to true.

username

public CassandraStorage.Builder username(@Nullable
                                         String username)

Will throw an exception on startup if authentication fails. No default.

password

public CassandraStorage.Builder password(@Nullable
                                         String password)

Will throw an exception on startup if authentication fails. No default.

maxTraceCols

public CassandraStorage.Builder maxTraceCols(int maxTraceCols)

Spans have multiple values for the same id. For example, a client and server contribute to the same span id. When searching for spans by id, the amount of results may be larger than the ids. This defines a threshold which accommodates this situation, without looking for an unbounded number of results.

spanTtl

public CassandraStorage.Builder spanTtl(int spanTtl)

Time-to-live in seconds for span data. Defaults to 604800 (7 days)

indexTtl

public CassandraStorage.Builder indexTtl(int indexTtl)

Time-to-live in seconds for index data. Defaults to 259200 (3 days)

build

public CassandraStorage build()
