    Merge #148778 #148784 148778: geomfn: adjust two tests to work on s390x r=yuzefovich a=yuzefovich `angleFromCoords` function uses `atan` to compute some geometry functions. s390x system has architecture support for that trigonometric function which can produce slightly different result than when computing via math operations, which resulted in a false positive failure in a couple of tests. This commit teaches those tests to use our custom float comparison function that only checks 15 significant decimal digits. Fixes: #145985. Release note: None 148784: logictest: adjust a few of geo tests for s390x r=yuzefovich a=yuzefovich Similar to other patches, we need to do some rounding for a couple of geo logic tests. This is the case since s390x has architecture support for trigonometric functions which are used when computing `ST_Segmentize` and `ST_Rotate` builtins. Note that the "rounding" is performed via regexp replacement on top of the textual result. Relatedly, we have a couple of tests that print inverted index keys, and for some shapes / geographies we use s2 library which also uses trigonometric functions. Thus, this commit adjusts those tests to account for the minor differences. This behavior suggests another limitation for heterogeneous clusters - we cannot guarantee to correctly read inverted geo indexes when the SQL pod and the KV / storage node run on different architectures. I don't think there is any concern for "pure" s390x clusters since they will behave consistently within the cluster. This limitation is filed as #148783. Fixes: #146001. Fixes: #146007. Fixes: #146109. Release note: None Co-authored-by: Yahor Yuzefovich <yahor@cockroachlabs.com>

    CockroachDB is a cloud-native distributed SQL database designed to build, scale, and manage modern, data-intensive applications.

    What is CockroachDB?

    CockroachDB is a distributed SQL database built on a transactional and strongly-consistent key-value store. It scales horizontally; survives disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention; supports strongly-consistent ACID transactions; and provides a familiar SQL API for structuring, manipulating, and querying data.

    For more details, see our FAQ or architecture document.

    Docs

    For guidance on installation, development, deployment, and administration, see our User Documentation.

    Starting with CockroachCloud

    We can run CockroachDB for you, so you don’t have to run your own cluster.

    See our online documentation: Quickstart with CockroachCloud

    Starting with CockroachDB

    1. Install CockroachDB: using a pre-built executable or build it from source.
    2. Start a local cluster and connect to it via the built-in SQL client.
    3. Learn more about CockroachDB SQL.
    4. Use a PostgreSQL-compatible driver or ORM to build an app with CockroachDB.
    5. Explore core features, such as data replication, automatic rebalancing, and fault tolerance and recovery.

    Client Drivers

    CockroachDB supports the PostgreSQL wire protocol, so you can use any available PostgreSQL client drivers to connect from various languages.

    Deployment

    • CockroachCloud - Steps to create a free CockroachCloud cluster on your preferred Cloud platform.
    • Manual - Steps to deploy a CockroachDB cluster manually on multiple machines.
    • Cloud - Guides for deploying CockroachDB on various cloud platforms.
    • Orchestration - Guides for running CockroachDB with popular open-source orchestration systems.
