Deprecated.

ENDPOINT_SNITCH_NAME

static final ConfigKey<java.lang.String> ENDPOINT_SNITCH_NAME

Deprecated.

SEED_SUPPLIER

USE_VNODES

NUM_TOKENS_PER_NODE

static final ConfigKey<java.lang.Integer> NUM_TOKENS_PER_NODE

Deprecated.

num_tokens will automatically be reset to 1 for each node if USE_VNODES is false.

DELAY_BEFORE_ADVERTISING_CLUSTER

static final ConfigKey<Duration> DELAY_BEFORE_ADVERTISING_CLUSTER

Deprecated.

Additional time after the nodes in the cluster are up when starting before announcing the cluster as up.

Useful to ensure nodes have synchronized.

On 1.2.2 this could be as much as 120s when using 2 seed nodes, or just a few seconds with 1 seed node. On 1.2.9 it seems a few seconds is sufficient even with 2 seed nodes

UPDATE

static final MethodEffector<java.lang.Void> UPDATE

Deprecated.

EXECUTE_SCRIPT

static final Effector<java.lang.String> EXECUTE_SCRIPT

Deprecated.

DEFAULT_SEED_QUORUM

static final int DEFAULT_SEED_QUORUM

Deprecated.

Sets the number of nodes used to seed the cluster.

Version 1.2.2 is buggy and requires a big delay for 2 nodes both seeds to reconcile, with 1.2.9 this seems fine, with just a few seconds' delay after starting.

DELAY_AFTER_FIRST

static final Duration DELAY_AFTER_FIRST

Deprecated.

Can insert a delay after the first node comes up.

Reportedly not needed with 1.2.9, but we are still seeing some seed failures so re-introducing it. (This does not seem to help with the bug in 1.2.2.)

DELAY_BETWEEN_STARTS

static final Duration DELAY_BETWEEN_STARTS

Deprecated.

If set (ie non-null), this waits the indicated time after a successful launch of one node before starting the next. (If it is null, all nodes start simultaneously, possibly after the DELAY_AFTER_FIRST.)

When subsequent nodes start simultaneously, we occasionally see schema disagreement problems; if nodes start sequentially, we occasionally get "no sources for (tokenRange]" problems. Either way the node stops. Ideally this can be solved at the Cassandra level, but if not, we will have to introduce some restarts at the Cassandra nodes (which does seem to resolve the problems.)

WAIT_FOR_FIRST

static final boolean WAIT_FOR_FIRST

Deprecated.

Whether to wait for the first node to start up

not sure whether this is needed or not. Need to test in env where not all nodes are seed nodes, what happens if non-seed nodes start before the seed nodes?
