-[YCQL]((../api/ycql/)) is a SQL-based flexible-schema API that is best fit for internet-scale OLTP apps needing a semi-relational API highly optimized for write-intensive applications as well as blazing-fast queries. It supports distributed transactions, strongly consistent secondary indexes and a native JSON column type. YCQL has its roots in the Cassandra Query Language.

 {{< note title="Note" >}}
 The YugabyteDB APIs are isolated and independent from one another today. This means that the data inserted or managed by one API cannot be queried by the other API. Additionally, there is no common way to access the data across the APIs (external frameworks such as [Presto](../develop/ecosystem-integrations/presto/) can help for simple cases).

-Note that we also set the [`--leader_failure_max_missed_heartbeat_periods`](../../../reference/configuration/yb-master/#leader-failure-max-missed-heartbeat-periods) option to `10`. This option specifies the maximum heartbeat periods that the leader can fail to heartbeat before the leader is considered to be failed. Since the data is geo-replicated across data centers, RPC latencies are expected to be higher. We use this flag to increase the failure detection interval in such a higher RPC latency deployment. Note that the total failure timeout is now 5 seconds since it is computed by multiplying [`--raft_heartbeat_interval_ms`](../../../reference/configuration/yb-master/#raft-heartbeat-interval-ms) (default of 500ms) with [`--leader_failure_max_missed_heartbeat_periods`]((../../../reference/configuration/yb-master/#leader-failure-max-missed-heartbeat-periods) (current value of `10`).
