Ben Johnson, autor NoSQL \u00falo\u017eiska BoltDB, predstavil projekt Litestream, ktor\u00fd poskytuje nadstavbu na organiz\u00e1ciu replik\u00e1cie d\u00e1t v SQLite. Litestream nevy\u017eaduje zmeny v SQLite a m\u00f4\u017ee pracova\u0165 s ak\u00fdmiko\u013evek aplik\u00e1ciami, ktor\u00e9 pou\u017e\u00edvaj\u00fa t\u00fato kni\u017enicu. Replik\u00e1ciu zabezpe\u010duje samostatne vykon\u00e1van\u00fd pozadov\u00fd proces, ktor\u00fd sleduje zmeny v s\u00faboroch s datab\u00e1zou a pren\u00e1\u0161a ich do in\u00e9ho s\u00faboru alebo extern\u00e9ho \u00falo\u017eiska. K\u00f3d projektu je nap\u00edsan\u00fd v jazyku Go a je distribuovan\u00fd pod licenciou Apache 2.0. <\/p>\n
V\u0161etky interakcie s datab\u00e1zou prebiehaj\u00fa prostredn\u00edctvom \u0161tandardn\u00e9ho API SQLite, t.j. Litestream priamo nezasahuje do \u010dinnosti, neovplyv\u0148uje v\u00fdkon a nem\u00f4\u017ee po\u0161kodi\u0165 obsah datab\u00e1zy, \u010do v\u00fdhodne odli\u0161uje Litestream od rie\u0161en\u00ed, ako s\u00fa Rqlite a Dqlite. Zmeny sa sleduj\u00fa prostredn\u00edctvom zapnutia WAL \u017eurn\u00e1lu (\"Write-Ahead Log\") v SQLite. Na \u00fasporu miesta v \u00falo\u017eisku syst\u00e9m pravidelne agreguje pr\u00fad zmien do sn\u00edmok (snapshotov) datab\u00e1zy, na ktor\u00e9 sa potom za\u010d\u00ednaj\u00fa hromadi\u0165 \u010fal\u0161ie zmeny. \u010cas vytvorenia sn\u00edmok je ur\u010den\u00fd v nastaveniach, napr\u00edklad sn\u00edmky je mo\u017en\u00e9 vytv\u00e1ra\u0165 raz za de\u0148 alebo raz za hodinu. <\/p>\n
Ako hlavn\u00e9 oblasti pou\u017eitia Litestream sa spom\u00ednaj\u00fa organiz\u00e1cia bezpe\u010dn\u00e9ho z\u00e1lohovania a rozdelenie za\u0165a\u017eenia na \u010d\u00edtanie na viacero serverov<\/a>. Podporuje sa prenos toku zmien do \u00falo\u017e\u00edsk Amazon S3, Azure Blob Storage, Backblaze B2, DigitalOcean Spaces, Scaleway Object Storage, Google Cloud Storage, Linode Object Storage alebo na ak\u00fdko\u013evek extern\u00fd hostite\u013e, ktor\u00fd podporuje protokol SFTP.
